Retargeting: How brands stay top of mind after you bounce

Retargeting is a digital marketing strategy that uses display advertising to re-engage people who have shown interest in your brand but haven’t converted into a sale. 

(Yes, it’s also why you feel like Big Brother is watching when that pair of shoes you clicked on once follows you around the internet.)

It works by tracking user behavior, such as site visits or clicks, and then serving customized ads to each user across platforms like websites, social media, mobile apps, or email. 

Is retargeting the same as remarketing?

Not exactly–retargeting is considered a subset of remarketing. It primarily uses ad-based channels and third-party data, whereas remarketing is a broader strategy that primarily uses owned channels and first-party data.  

Remarketing strategies often incorporate retargeting channels and data sources. For example, a CRM-based remarketing campaign may trigger social ads (retargeting) in addition to personalized emails. The idea is to reach your target audience at multiple points along the buyer’s journey.

Here’s a quick breakdown:

Term	Scope	Channels Used	Data Types Used
Remarketing	Broader strategy; supports retention	Email, SMS, push, CRM ads, retargeting	First-party: Website behavior, email and CRM lists, app activity, user account info, onsite conversions
Retargeting	Ad-specific strategy (subset of remarketing)	Display ads, social ads, video ads, mobile in-app ads	Third-party: purchased audience lists, third-party cookies, site visits from publisher networks*with the phasing out of third-party cookies, retargeting is becoming more reliant on first-party data

Traditionally, remarketing focused on existing customers, while retargeting was used to re-engage prospects. But today, both strategies are used more interchangeably across audience types, as customer journeys have become more fragmented and multi-channel.

But more important than strict definitions is understanding that both remarketing and retargeting share the same goal: to re-engage people who have already interacted with your brand and move them closer to conversion.

A step-by-step look at retargeting

Businesses use retargeting to increase the effectiveness of their marketing spend by re-engaging people who showed interest but didn’t convert. 

For example, it’s more cost-effective to target someone who has already browsed your website or even added an item to their cart but didn’t purchase, versus targeting a brand new prospect who is just learning of your brand. The first user is already past the brand awareness stage, so you need fewer resources and budget to move them further down the funnel. 

The process involves four key steps:

1. Tracking
   When someone visits your website or app, a pixel or tag (a small piece of code) is deployed and captures their behavior. This behavior includes everything from the pages they view, what they click, and which actions they take. That information is stored for future reference by a cookie that gets dropped into their browser.

2. Segmentation
   Once users have been tracked, they need to be segmented (or organized) into audiences based on certain behaviors or intent. For example, someone who viewed a product page might go into one segment, while a repeat customer belongs in another. Typically, you will create these segmentations in either your CRM, email marketing tool, or ad platform (like Facebook or Google Ads).
   
3. Personalization
   You can then tailor messages or offers to each group to fit their stage in the customer journey. This makes your ads feel more relevant and timely, whether it’s a discount, a reminder, or a nudge toward a product they showed interest in. This is done by linking your audience segments to specific ad creatives or dynamic templates within your ad or email platform.

4. Channel targeting
   Lastly, your retargeting ads are delivered across the right platforms and devices, like social media, apps, organic search, or websites your audience frequents. You’ll choose these channels during campaign setup in tools like Google Ads or Meta Ads Manager, depending on where your audience spends the most time.

An example of retargeting in action: 

Let’s say that the pair of shoes “following” you around the internet is doing so because you added them to your cart but didn’t check out. A tracking pixel captured your visit, added you to a segment of cart abandoners in the company’s ad platform, and is now strategically appearing on platforms you use.

One day later, you visit a news site and see a personalized display ad featuring the exact pair of shoes, accompanied by other similar styles. The tracking pixel has revealed that you spend lots of time on this news site, which is why you’re seeing the ad there. It’s timed just right to nudge you back to their site to complete the purchase. This exemplifies the power of retargeting: using data and timing to turn intent into action. 

How tracking works (pixels, cookies, and data types)

A pixel is a small snippet of code that sends data (like page views or clicks) to a server. Think of it as a tiny messenger that lives on your website, where it tracks a user’s behavior on your site and then sends that information back to your ad platform, so you can use it to inform your retargeting strategy later. 

A cookie is the file that stores that information, and it lives in the user’s browser. It can recall information like which pages on your site they visited or which products they added to their cart. If they later visit another site that also has a pixel from the same ad platform (like Meta or Google), that platform can recognize the user and display retargeting ads for your brand.

Retargeting only works across sites using the same pixel

For example, you browse running shoes on a website that uses the Meta Pixel. Later, you visit a news site that also has the Meta Pixel installed. Because both sites use Meta’s pixel, Meta recognizes you and shows you an ad for those same running shoes while you’re reading the news.

This highlights how pixels and cookies work together: the pixel tracks the behavior, and the cookie stores the behavior data. 

First-party vs. third-party data

First-party data is any information that comes from your own website, app, or CRM. Third-party data comes from outside sources, like data brokers or ad networks.

As third-party cookies fade out due to privacy laws, marketers should double down on first-party and zero-party data (see below).

Segment your audience for smarter follow-up

Once you’ve captured user behavior, the next step is to break your audience into groups based on what they’ve done (or what they seem to want). This is what turns a generic ad campaign into something that actually resonates.

Be strategic about how you segment. Get granular with how you decide to divide users (but not so granular that your audience lists are very small, which will prevent you from accurately tracking their effectiveness). 

Example: Targeting runners vs hikers with customized follow-up

Let’s say a user browses running shoes and hiking boots on your website. Instead of putting them into a general “shoe shopper” group, they are put into two separate groups: one for runners and one for hikers. This allows you to re-engage them with messaging that speaks directly to their interests, while also helping you test out which messaging will be most effective (e.g., did they click on the running shoes ad, or the hiking boots ad?). 

But keep in mind: if your segments are too narrow, your audience lists may become too small to deliver ads consistently or generate meaningful performance data. As a rule of thumb, aim for at least 1,000 users per segment to ensure your campaign can run and produce reliable metrics, especially on platforms like Meta or Google Ads. 

---

Note: You can add a contact to more than one audience segment. Since users might show multiple interests or behaviors, adding them to multiple tests helps you figure out what will resonate best with them. However, adding them to lists without applying any exclusions can result in wasted ad spend if you’re retargeting the same prospect repeatedly. Learn more about how exclusions work and their benefits.

A few common ways to segment:

• First-time vs. repeat visitors
• Product page viewers vs. pricing page browsers
• Abandoned cart users vs. recent customers

Each group needs something different to move forward. For example:

• Someone who visited your pricing page might need a side-by-side comparison or a solid testimonial to feel confident
• Someone who bounced from a product page might respond better to a quick reminder or a small discount

The point is that when your follow-up feels relevant, it works. When it feels random, it gets ignored. Smart segmentation not only improves campaign performance but also helps you build trust by showing users that you understand what they actually care about.

Personalization: messaging that resonates 

Segmentation gets your audiences into the right buckets, but personalization is what makes your retargeting actually resonate.

Tailoring your messaging based on user behavior, funnel stage, or preferences turns generic ads into helpful nudges.

Get started with

Here are a few ways to personalize retargeting ads:

• Behavior-based: Show the exact product they viewed (dynamic retargeting), or recommend similar items
  
• Funnel-aware: Push testimonials to pricing page visitors or offer discounts to abandoned cart users
  
• Customer status: Serve loyalty perks to existing customers or invite repeat buyers to join referral programs

The more aligned your messaging is to a user’s needs or journey, the more likely it is to drive action.

Take these two ads in the “Sponsored” section of a Facebook feed, for instance:

Both ads are coming from sites the user recently visited.

The top ad promotes an upcoming beach volleyball camp—a smart move, since the user attended a similar camp from that same company just a few weeks ago. The company used that information to retarget them with relevant upcoming events. This is an example of retargeting to an already existing customer (you don’t have to limit retargeting outreach to just prospects). 

The other ad uses dynamic retargeting (showing users the exact product they previously viewed). In this case, it’s the same swimsuit the user had been browsing. It’s a subtle reminder designed to reignite interest and nudge the user toward a purchase.

Types of retargeting campaigns (and when to use them)

No two retargeting strategies are the same, and that’s exactly what makes retargeting such a powerful tool for converting your audience. Depending on your goals, audience, and where someone is in the customer journey, different types of retargeting campaigns offer unique advantages.

Let’s review the key types of retargeting campaigns, how they work, and when to use each one to get the most impact from your strategy.

Site-based retargeting (standard pixel-based)

This is the most common form of retargeting that’s used by both site owners and advertising platforms. It uses a small piece of code (typically a pixel) on your website to track visitors and show them ads after they leave your site.

Best for: Reminding users about your brand, re-engaging abandoned cart visitors, or nudging return visits from high-intent traffic.

Email-based retargeting (CRM-based)

This method (also thought of as traditional “remarketing”) uses email addresses from your CRM or customer lists to serve ads on platforms that support custom audiences (like Facebook, Google, or LinkedIn).

Best for: Re-engaging known leads, past customers, or blog/update subscribers with personalized ad messaging.

Dynamic retargeting (product-focused)

Dynamic retargeting automatically shows ads for the specific products or services a user viewed on your site. It pulls from your product catalog to tailor the ad experience on platforms the user frequents, such as social media, mobile apps, and organic searches. 

Example: This user browsed products on Men’s Wearhouse and was later served retargeting display ads of those exact products on the news site, Daily Mail:

Daily Mail was not subtle about its ad placement, but that’s the point. Dynamic retargeting puts the right products in front of the right users, exactly where they’re likely to see them. This level of personalization not only boosts relevance but also increases the likelihood of re-engagement and conversion.

Best for: ecommerce or SaaS sites looking to drive conversions through highly personalized ads based on individual browsing behavior.

Social retargeting (platform-based)

Platforms like Facebook, Instagram, LinkedIn, TikTok, and even community-driven networks like Reddit allow you to build retargeting audiences based on platform engagement or your own site data.

Example: An American Express (Amex) customer browsed the Amex website to explore high-yield savings account options. Later that day, they were served a retargeting ad in their Reddit feed promoting that exact account: 

The ad featured a woman looking at ultrasound photos, subtly reinforcing the theme of saving for a growing family. Amex likely used customer data and behavioral signals to tailor the creative to the user’s life stage and financial goals, making the message feel more relevant and timely.

In this case, Reddit may have provided the right mix of demographic targeting and intent signals, especially if the user had engaged with threads related to personal finance, parenting, or major life events.

Best for: Staying top-of-mind with users who spend more time on social media and increasing brand awareness with engaging ad formats (e.g., video or ad carousel).

Emerging methods

Programmatic retargeting

Programmatic platforms use AI and real-time bidding to buy ad space across thousands of websites, apps, and channels, including Connected TV (CTV) and audio. They help you deliver smarter, more precise retargeting based on user behavior, context, and intent.

Example: A brand uses a programmatic platform to target the decision makers of a B2B SaaS company who viewed its pricing page. It serves each of them customized ads across platforms like business news sites and LinkedIn, featuring client testimonials and a demo sign-up. The ads are optimized in real time based on industry and company size.

Best for: Brands looking to scale across digital touchpoints, especially in brand-building or higher-consideration campaigns.

Connected TV (CTV)

Serve retargeted video ads on smart TVs and streaming devices through platforms like Hulu (now owned by Disney), Roku, or YouTube TV.

Example: A user browses hiking boots on your website, then later sees your ad while watching Hulu on their smart TV.

Best for: Visually engaging brands that want to stay top-of-mind in a lean-back, non-scroll environment.

Audio/podcast retargeting

Re-engage listeners through platforms like Spotify or programmatic audio networks that support real-time ad bidding (note: not currently supported by Apple Podcasts).

Example: A user visits your product page, then hears your brand’s audio ad later that day while streaming a podcast on iHeartRadio.

Best for: Brands with a strong storytelling angle or those targeting multitasking users during workouts, commutes, or errands.

US spending on AI-powered search ads is projected to grow from just over $1 billion in 2025 to nearly $26 billion by 2029—a strong sign that you should start familiarizing yourself with AI-enabled retargeting (if you haven’t already). 

What retargeting can do for your brand

Retargeting empowers brands to make the most of their marketing budgets. It allows them to stay top of mind for users who have already interacted with their brand, versus spending that same budget on brand awareness campaigns for cold prospects that will take longer to convert (and at a lower conversion rate). 

Whether you’re looking to increase conversions, reduce acquisition costs, or deepen customer relationships, retargeting helps you make the most of your existing traffic. 

Here’s how it delivers real impact across the customer journey:

Improve conversion rates

Retargeting doesn’t just boost conversion rates by targeting people who have already shown interest—it also reinforces your brand awareness campaigns and makes them more effective.

Enhance ROI through targeted spend

Retargeting uses audience segmentation to reach the right people (versus just more people). This means less wasted ad spend and a much better chance that every dollar you invest moves someone closer to buying. 

Lower cost per acquisition (CPA)

Since retargeting re-engages people already familiar with your brand, it typically costs less to turn them into a customer, versus a “cold” prospect exposed to your brand for the first time. These “warmer” leads are quicker to convert, resulting in a lower average cost per conversion.

Increase customer lifetime value (CLTV)

Customers are far more likely to buy again compared to cold prospects buying for the first time. Retargeting takes advantage of this by presenting customers with upsells, cross-sells, or loyalty programs. This helps strengthen the overall value of each customer relationship over time. 

Strengthen brand recognition and credibility

Industry standards suggest it takes seven to eight exposures and/or engagements with a brand before a purchase happens. Retargeting helps reinforce your brand message and build familiarity, even if prospects aren’t quite ready to convert. 

Pro-level retargeting tactics to increase your ROI

Once the foundation of your retargeting strategy is established, it’s time to explore more advanced strategies. The most effective campaigns take a data-driven approach and factor in everything from audience signals, behavioral context, and user intent insights to focus on the users most likely to convert, and serve them the most relevant ads. Explore the expert-level strategies below to help you fine-tune your strategy. 

Get specific with your audience

Avoid just targeting everyone who visited your site. The best retargeting campaigns understand each of their visitors and what will resonate with them best. Try breaking your audience into groups based on a few key signals:

• Behavioral (what they did): Maybe they watched most of your video, checked out the pricing page, or chatted with support. Each of these behaviors hints at where they are in their journey. 
  
  If you notice they spent five minutes on your pricing page and then chatted with support, that indicates high conversion likelihood. You could retarget them with a testimonial ad that positions you against a competitor. This saves them the research and potentially nudges them to book a demo or make a purchase.
  
  On the flip side, if they left your page just as soon as they landed on it, don’t spend valuable ad dollars trying to retarget them. It will likely be a waste of time and money in the long run.
  
• Contextual (where they came from): Segment users based on whether they found you through social, email, a blog post, or any other channel. Each source usually indicates a different user goal.
  
  For example:
  
  A user who came through Instagram might just be browsing and looking for entertainment. You could target them with a brand awareness ad that uses appealing lifestyle imagery (versus a hard sell) to catch their attention. A blog reader is likely researching a specific problem or topic—retarget them with a related, more in-depth article or content that moves them further down the funnel.
• Intent-driven (how serious they are): Someone who came back multiple times or compared products is probably closer to converting than someone who bounced quickly.
  
  Factor this insight into your strategy. Don’t waste your budget on the quick bouncer. Instead, put it towards the user who has shown more intent. Target them over the span of a few days or more with high-intent ads, such as limited-time deals, free trials, or a product demo video.

Avoid annoying your audience (AKA ad fatigue)

More is not necessarily better when it comes to retargeting. You don’t want to inundate users with ads and risk wasting ad dollars on uninterested people or worse, drive interested people away with desperate or pushy efforts that feel invasive. 

A few general rules of thumb: 

• Start with a handful of daily ad impressions and tweak depending on performance
• Rotate ad creatives so users don’t see the same repeat ad
• Give users a breather from ads who have recently converted in some way (whether by a purchase or a form fill) so you don’t irritate new, happy customers 

Match your message to where they are in the journey

Use funnel-specific messaging to reach each person in a way that resonates best with where they’re at in their customer journey.

• Awareness (just learned of your brand): Show them something light, like a helpful blog post, a testimonial, or a video that tells your story. 
  
  For example, this banner ad from Korn Ferry appears at the top of the Forbes homepage:
  
  
  
  At first glance, you can’t be sure what Korn Ferry does. It shows a brief video slideshow of scientists in a lab and farmers in a field, with a title that reads, “Powering the people” and copy below, “Who power the performance of organizations worldwide.” The goal here isn’t to sell—it’s to spark curiosity and build initial brand recognition without overwhelming the viewer.
  
  This is a prime example of a brand awareness ad, where it gives you just enough to make you wonder, “What is this company about?” The vagueness is intentional and often compels users to click so they can learn more. 
• Consideration (sizing up your brand with competitors): Highlight what makes you different, such as benefits, case studies, or a product demo.
  
  For example, this promoted ad from Fireblocks appeared in a user’s LinkedIn feed: 
  
  
  
  It combines an eye-catching visual with a featured asset (case study), plus a testimonial from a well-known customer, Revolut. Since LinkedIn is a platform built around credibility and professional trust, using social proof here is especially powerful. It’s a strong example of content crafted to build confidence in your brand and move users closer to a decision.
• Decision (just about to convert): Create a sense of urgency to help them make the leap. This could be a flash sale, promo code, limited-time offer, or abandoned cart reminder. 
  
  In this example, the user was browsing the /Pilates thread on Reddit and was immediately served a pilates-related ad from a news site via display retargeting shortly after:
  
  
  
  The ad stands out by using bold red, all-caps lettering with time-sensitive messaging like “TOMORROW MORNING” to convey urgency. This kind of visual intensity and time-based language works well at the decision stage by tapping into the fear of missing out (FOMO) and encouraging the user to take action. 

Privacy-compliant retargeting (in a cookie-less future)

From cookie-consent pop-ups on every website to tracking-permission prompts in every app, you’ve likely noticed privacy regulations tightening everywhere.

Governments worldwide are stepping in to give people more control over how their data is collected and used. Laws like the GDPR in Europe and CCPA in California require businesses to be upfront about tracking and get clear permission before collecting personal information. These regulations are a direct response to growing concerns about online privacy, data misuse, and a lack of transparency.

At the same time, tech platforms are making their own privacy changes—many of which directly impact retargeting: 

• Cookie deprecation: Browsers like Safari, Firefox, and Chrome are ending support for third-party cookies, making cross-site tracking and retargeting harder.
• iOS tracking limits: Apple’s App Tracking Transparency forces apps to ask for tracking permission. Most users say no, reducing mobile attribution.

Are third-party cookies completely going away?

They’re being phased out, not completely gone yet. Most major browsers (Safari, Firefox) have already ended cookie use, with Chrome expected to finish its phase-out by the end of 2025. 

Even after full deprecation, third-party cookies may still technically exist because the underlying web technology (HTTP and JavaScript) still supports the ability to create cookies. However, modern browsers will render them useless by blocking or completely ignoring them. 

What about user consent?

User consent does not override browser restrictions on third-party cookies. Even if users opt in via a consent banner, browsers may block third-party cookies from being set or accessed anyway.

Basically, browsers will have the final call on privacy settings, regardless of user opt-ins.

How to implement consent-first retargeting 

Consent-based retargeting means you only collect and use data from users who have explicitly agreed to tracking. That includes everything from cookie consent banners to opt-ins for email or SMS marketing.

This approach sets you and your visitors up for success: effective retargeting that respects privacy and gives users a sense of control over their own data.

Let’s review the steps to build a consent-first retargeting strategy.

Add a cookie consent banner to your site

There are four different ways to do this: 

• Website builders/ CMS tools: Platforms like Wix, WordPress, and Squarespace often include built-in cookie consent features, making basic compliance easy to set up
• Third-party consent management platforms (CMPs): For more complex needs—such as managing third-party cookies, offering multilingual support, or customizing banner design—consider dedicated CMPs like CookieYes, Cookiebot, or Osano
• Google Tag Manager (GTM): If you’re already using GTM, you can add a custom HTML tag with a trigger to manage cookie consent behavior
• Manual JavaScript implementation: Developers can build a fully custom consent banner using HTML and JavaScript (more technical, but ideal for teams that need full control)

---

Note: Check out Google’s CMP Partner Program if you want a CMP that’s verified by Google and seamlessly integrates with its tools, like AdSense and Google Analytics 4 (GA4). 

---

Include an “opt-in” checkbox in your email and SMS marketing 

Follow these steps in whichever CMS or email marketing tool you use to ensure you’re only targeting users who have explicitly opted in to data tracking: 

• Add a clear checkbox at signup for personalized emails (set it to unchecked by default)
• Explain how their data will be used (e.g., personalized product recommendations)
• Tag users who consent in your email platform (creating a segmented list of just consenting users)
• Only send behavior-based emails (like cart reminders) to that segmented list
• Include an obvious opt-out or preference link in every email

Zero-party data tactics for a cookie-less future

Zero-party data is information that people have intentionally and proactively shared with your brand. 

Examples include quiz responses, chat support pop-up conversations, loyalty programs, surveys, SMS polls, account settings, or user profile updates. Unlike first- or third-party data, zero-party data doesn’t require tracking pixels or cookies, making it ideal as privacy regulations tighten.

For example, this retargeting email from Liquid I.V. uses a one-time discount code to help entice users to take their survey: 

By offering a small incentive, the brand collects valuable zero-party data (e.g., flavor preferences, hydration habits, or shopping motivations) directly from the user.

This data is incredibly powerful because it’s both voluntary and accurate. Since the user chooses to share it, it’s more likely to reflect their actual preferences while respecting privacy. It also allows the brand to build more relevant and effective retargeting campaigns without using third-party data or tracking pixels. This could translate to showing more personalized product suggestions, sending reminders based on past responses, or segmenting audiences by their responses.

As privacy expectations take front seat, zero-party data is more than a workaround; it’s a competitive advantage that helps brands build trust and deliver better experiences.

How to use zero-party data in retargeting:

• Sync it with your CRM or customer data platform (CDP): Tools like Meta’s Conversions API and Google’s Customer Match now make it easier to activate CRM/CDP audiences using custom attributes. Other popular platforms that allow zero-party data syncing include: Amazon ads, TikTok ads, LinkedIn ads, Pinterest ads, and Snapchat ads.
  
  While this may all sound like a lot to process, rest assured, the payoff will be worth it. Not only will you be completely privacy-compliant, but campaigns based on zero-party data almost always perform better because they’re based on declared, high-intent information rather than observed behavior.
• Use it to customize messaging across channels: For example, use loyalty member data to send a “VIP-only” early access offer to a high-level loyalty member across email and SMS. Or show exclusive discount ads across social media channels to loyalty members who recently earned enough points for a reward.
• Build dynamic segments with it: Use data such as survey or poll answers to create segmented audiences. These audiences can trigger personalized email flows and retargeting ads, resulting in more relevant experiences and higher conversion rates across channels.

While the road to a cookie-less world has already proven long, it’s a win for both brands and customers in the big picture. You’re building deeper, more transparent relationships with your audience.

And the best part is that the more your audience shares with you, the smarter and more effective your marketing will become.

Optimizing retargeting and attribution for better results

Like most things in marketing, a “set it and forget it” mindset won’t cut it if you want a truly successful retargeting strategy. 

You want to understand what’s working, why it’s working, and how you can make it work even better. This requires a data-driven approach.

Here’s how to approach the full cycle:

1. Accurate measurement of incremental lift and ROI from retargeting

It’s easy to overestimate the ROI of retargeting (and not give other elements in the customer’s journey more credit) since it’s often the final step before a conversion. But to really understand its effectiveness: 

• You need to measure its incremental lift: This involves using holdout groups (who are not exposed to retargeting ads) to determine how many conversions would have happened without the ads.
  
  For example, let’s say you’re running a retargeting campaign for a makeup brand targeting visitors who viewed a product but didn’t buy. You only serve ads to half of the group (the test group) and don’t serve any ads to the other group (the holdout group). 
  
  After, say, two weeks, the test group resulted in 200 conversions and the holdout group resulted in 110 conversions. This means that your incremental lift was 90 conversions (200-110)–meaning those 90 conversions were directly influenced by your retargeting efforts. 
  
  Rather than assuming all 200 conversions to your retargeting, you now know that 45% of those would’ve happened anyway, allowing you to better assess ROI and refine your strategy.

Use A/B testing frameworks (like audience segmentation or creative assets) to better understand how retargeting performs, especially with people at different stages of interest or intent.

2. Recommended tools and attribution models to measure and optimize performance

There are lots of powerful analytics tools you can use to help evaluate the full user journey and optimize ad delivery. Such as: 

• Tools: GA4, Meta Ads Manager, Kissmetrics, Rockerbox, and Adobe Analytics offer event tracking, conversion modeling, and cross-channel visibility.
• Attribution models:
  • Multi-touch attribution (MTA) distributes credit across all touchpoints, helping you more accurately gauge the role of retargeting in each customer journey. It also helps shine a light on which marketing efforts are most effective for new customer acquisition and long-term engagement.
  • Data-driven attribution (DDA) models (available in GA4 or Meta) use machine learning to assign credit based on real performance.
    
    Example:
    If a user first sees a display ad, then clicks a search ad, and then converts via a retargeting ad, DDA might assign: 10% credit to the display ad, 40% to the search ad, and 50% to the retargeting ad
    
    Just make sure to feed it enough data so it can run these reports accurately. For example, Google Ads usually requires at least 300 conversions and 3,000 ad interactions in the past 30 days to enable DDA.
  • Post-click vs. post-view attribution: Post-click attribution assigns conversion value when a user clicks an ad, whereas post-view attribution also credits users who only saw an ad. 
    
    You should compare the two attribution metrics to avoid over-crediting view-based interactions that didn’t actually influence the user’s decision. Relying only on post-view can exaggerate the perceived impact of your retargeting campaign and result in wasted allocated budget. 

3. Common pitfalls in retargeting attribution (and how to resolve them)

Attribution can be misleading if not handled carefully. Here are typical errors and how to address them:

• Last-click bias: As mentioned above, it’s easy to overemphasize the impact of retargeting when it’s the last click before a conversion. You can avoid this by adopting multi-touch or data-driven attribution.
• Retargeting overlap with other campaigns: When users are exposed to multiple channels, it’s hard to tell which one deserves credit. Use deduplication logic (which ensures a conversion isn’t counted across multiple channels) and platform integrations to map holistic user journeys. The stronger your integrations are, the more accurate and seamless your attribution will be.
• Ignoring view-through conversions: While post-view data can be informative, avoid assuming it caused the conversion. Validate with incremental lift studies or probabilistic modeling (which estimates the likelihood of conversion from a specific touchpoint based on the analysis of large sets of user behavior data). 
• Measurement gaps due to privacy changes (e.g., iOS 14+): To regain visibility, use solutions like:
  • Server-side tracking: Instead of relying just on browser pixels, this method sends data straight from your server. That means more accurate tracking—and it’s less likely to break when browsers tighten up privacy rules.
  • Enhanced conversions (Google): If pixel data goes missing, Google can help fill in the gaps by securely matching hashed details (personal info that’s been scrambled to keep it unidentifiable) like an email or phone number with user activity. 
  • Aggregated event measurement (Meta): Meta’s solution to iOS privacy changes—it lets you track and prioritize your most important website events in a way that still respects user privacy.

With only 41% of marketing teams using attribution modeling to measure ROI, there’s a huge opportunity for brands to stand out by getting retargeting attribution right.

Laying the groundwork for high-impact retargeting

Success with retargeting comes down to smart strategy, seamless tracking, and understanding the tools that help you stay visible (without overstepping privacy boundaries). Build your campaign on a strong foundation with these resources:
