Link Building Tool Review: Ahrefs

Ahrefs is a suite of tools that contains “the largest index of live links.” There is a free version and a premium version, an API, and an affiliate program. They have their own index, putting them into the same arena as SEO Moz and Majestic, and they post some useful stuff on their internal blog digest.

Pricing starts at $79 a month and goes as high as $499 a month for more advanced plans. All plans offer a nice discount if you pay for a year upfront.

Now that the basics are out of the way I have to say that I absolutely love the Ahrefs tool. It’s fast and the graphical representations are very easy to understand (even for a novice I imagine.) In this suite you’ll find a Site Explorer, Keywords Analysis, Backlinks Report, Domain Comparison, Batch Analysis, and Competition Analysis tools.

For our purposes here, I’ll be going through the Site Explorer, Backlinks Report, and Competition Analysis sections.

1.  Site Explorer

The Site Explorer gives you an overview of a domain. You can find technical site information and social signal info here as well. Once you’ve run a report you can access it again in the History area, which is right beside the box where you enter the URL. You get the following information on the Overview tab:

  • Referring Pages
  • Total Backlinks
  • Referring IPs
  • Referring Subnets
  • Referring Domains (broken down into .gov, .edu, .com, .net, and .org)
  • Backlinks Types (broken down into text, dofollow, nofollow, sitewide, not sitewide, redirect, image, frame, form, .gov, and .edu)

Each of the above metrics has a clickable number so that you can see more details. There is also plenty of information about your anchors here, represented in bar charts. For a chart-happy person, this overview tab is fantastic.

Take a look at just one of the reports you’re given:



Up top on the Overview navigation bar, you can view the following:

  • External
  • New/Lost
  • Anchors
  • Pages
  • Referring Domains
  • Linked Domains
  • Site Issues
  • Raw Export

As I’ve mentioned before in a review, having the raw data to export is critical for me with any backlinks tool.

Let’s take a look at the Site Issues tab for a minute because this is the kind of thing I’d usually consult a separate tool for. You get a list of your errors like HTTP Timeouts, a list of warnings (your title text is too short, you’re missing descriptions, 302 issues, etc.) and a list of notices (permanent redirects, overly long URLS.)

Considering the amount of times I’ve seen site problems affect a site’s performance online (it’s not always links, remember) I think this type of information is necessary in a link tool.

The Pages tab is also nice because of the social information you’re given. Beside each page’s URL, you can also access organic keywords for the page. However, in testing this section, I didn’t always get social data, which was a bit disappointing.

Still, when it’s working, you get information like this:

social data

The Anchors tab allows you to see a breakdown of the number of referring domains, backlinks, and percentage for each anchor. You can click on the + button beside the anchor and it brings you to a list of the referring domains for it. You can also filter the anchors by how many words are in the anchor.

The New/Lost tab graphically shows you how many links you’ve lost and gained. If you click on a date on the calendar, you’ll see a list of the links that you lost and/or gained. However, as is the case with any system, sometimes you’ll see something that needs to be double-checked.

In my case, a link was shown to be lost but I double-checked and sure enough, it was actually still there, so don’t freak out about lost links. There could be various reasons why a link is reported as lost. It’s very cool to be able to see your new links by date as well.

2.  Backlinks Report

The Backlinks Report is also graphics-heavy and very easy to understand at a glance. You’re brought to an overview screen initially so you can see your subdomains, referring domains, anchors, target pages, and TLDs broken down nicely here, and some of the sections list out the top values which have corresponding links to other reports, so the potential for almost getting lost in analysis is high if you’re a data junkie.

Let’s click on the Backlinks tab and go through that. Each of your links is listed out with an Ahrefs Rank (their proprietary metric), social information for Google Plus/Facebook/Twitter, target page, anchor used, the type of link, and when the link was last updated in their system.

Again, much of this information has links that can lead you to more detailed reports. Your list of links is listed by Ahrefs Rank from highest to lowest but the whole report is very sortable depending upon how you want to view it. It’s also exportable.

Here’s what you’ll see, and note the filtering capacity up top:

Ahrefs Backlinks

While we’re on the subject of Ahrefs Rank, let’s point out what that metric is. It’s kind of like Google’s PR (or any other tool set’s proprietary metric for evaluating pages) but you can read more about it on their FAQs page, which also lists some other great information.

What I really like here is seeing the social data for the sites linking to my site. Obviously, you can have some great older links that have no social love going on because when those links were placed, we weren’t Twitter-happy for example (like the Sphinn link in my above example), but I do think this is very valuable information for your newer links.

The Pages view is nice and lists all your site’s pages along with the Ahrefs rank, social information, number of backlinks, how many nofollowed links, number of linking domains, IPs, and subnets.

If you click on a page you see more information about the links coming to it, including the anchor, types of links, and when the system last updated the information. I love this for finding social mentions of pages because in digging through those, there were some that I had not seen for Google Plus.

The Domains tab lists your referring domains and is set to list them alphabetically by default, but you can change how they’re sorted. In using this, I would always sort by another metric whether it’s Ahrefs or the number of backlinks but to be honest, seeing your domains listed alphabetically may cause you to notice some that you hadn’t always paid as much attention to. You can click on a domain and then be directed to a link report for it, so if you’re interested in that, this is a good section for you.

The IPs and Subnets sections may not be ones that everyone uses, but when you’re dealing with a massive link account, this is fantastic information.

3.  Competition Analysis

This section is currently in Beta but it’s too interesting to pass up. You enter a keyword and a URL and choose which version of Google you want to run the tool on, whether it’s .com or one of about 20 country-specific versions.

For example, I ran a test on the keyword “link building” for my site, in Here’s what I got:



This shows the URLs ranking for that term along with valuable data about them, such as the number of referring domains to those pages, the number of referring domains to the root domain, and social information. You also get a small graph that charts their backlinks.

After the top 10 are listed, you’ll see the information for the URL that you entered so you can compare it to the top 10. You then get a great little section of charts that sum up your competition compared to you.

This tool took the longest of any to run, but again, it’s in beta, and it’s still faster than some tools. As mentioned before about social data, I couldn’t always load that information. Google Page Rank wasn’t working at one point either.


  1. The graphical representations that you see on each dashboard are fantastic and are a quick way to get a good overview. If you’re a person who likes to see a lot of visual data, you’re going to love this.
  2. It’s fast. If I’m doing an on-the-fly check for a client who’s just called, I need speed.
  3. It’s intuitive and well laid-out, with almost every piece of data linking to more information. You could literally loop around in the data for hours. It’s so well laid out that even someone who has never used a link tool should be able to figure out what to do pretty quickly.
  4. I could not find a single feature that I wanted in a tool that was not present here already.


My only issue with this tool was that I did not always get social data the first time I ran a report, and at one point I couldn’t pull any Google Page Rank information either.


In case you couldn’t tell, I love this tool. I was not asked to review it (sometimes that happens) but instead chose to simply because I use it and think it’s that good. They have live support in case you need it but as I said, it’s incredibly intuitive. I think this tool is poised to become a massive player in the market.

    I have no opinion on your analysis of AHREFS as a tool but I do have an opinion of their bots policy, the execution of their bots activity and their response to the robots.txt protocol.


Namely, they are a bunch of site-spammers.

Their bot was constantly hitting my modest two-page site, up to 40 times per 24 hour period, and I wrote to them requesting that they diminish or cease their visiting practices. They responded suggesting I use the robots.txt protocol to control their bot, but I disagreed, saying it is/was their problem, not mine.

    When they did not do anything I wrote again threatening “dire consequences”, and received a response saying they would stop their bot visiting my site.

    Three days on and there had been virtually no change in the visitations from their crawler, so I used my robots.txt file to hopefully send them away.

    Another three days on and the visits had decreased but not stopped.

    Now after two weeks, the visits are down to a few per day, but obviously they do NOT respect the robots.txt protocol.

    So what can I say – they are spammers and they don’t respect the robots.txt protocol, so I take with a grain of salt any opinion you may have of their value.

    From their website: “We use data gathered by AhrefsBot web crawler. If you ever decide to block it – see instructions at (consider dropping a note to us if you think there is a problem with the bot).” Maybe you can point out that there does seem to be a problem.

  • Alan

    Wow nice ad for how much they pay for it?

  • JulieJoyce

    They did not pay for it nor did they ask for a review. I simply think it’s a fantastic tool.

  • AnilValvi

    Thanks Julie, Very informative post and very well represent about I like the professional plan. Usually am familiar with the seomoz pro tools but atleast one time i will use it aherfs. Keep continue blogging. Have a great day !!!

  • Andy Roberts

    Hi, maybe I’ve missed the point but the title of your post was link building tool, shouldn’t it have been link analysis tool?

  • Rajesh Magar

    “I think this tool is poised to become a massive player in the market.”

    That’s completely true and as per their survive and they charging for that is quite adjustable too.

    I am in love with this tool as well, Thanks for you clarification!

  • sharithurow


    I really have to say/write this. These SEO software companies REALLY need to hire usability/interface firms. Their interfaces are rather awful. I like the tool, but I am a search expert. You have no idea how difficult it is for me to train people to use these tools.

    I tend to test on newbies rather than expert users. An added feature might make the experts happy, but it likely will confuse the heck out of newbies. Whereas if you make the software easier to use for newbies? You also make it easier to use for experts.

    Yeah, the “spam/bots” thing is a problem.

    PUH-LEEZ convince them to hire a good usability/interface firm!

  • JulieJoyce

    I don’t think you can properly build good links without good analysis, so that’s the reason for the title.

  • JulieJoyce

    Excellent point…they tend to make sense to me but I’ve never tried to train a client to use one.

  • Cody Sharp

    In my experience, Ahref’s is a good tool. I’m not sure if it is worth spending the money on when compared to similar tools like Raven, Majestic and SEOMoz. That would be an interesting article to compare all of them.

  • JulieJoyce

    Rob Kerry did a good job on an SEO Book post…

  • Cody Sharp

    Awesome. Thanks!

  • jonathan

    and it wont hurt to bring in some rogue clicks for people looking for actual link building tools :D

  • Alan

    I agree it is a good tool, I actually use them. fantastic? no. but now I really know they paid for this. Most content marketing is paid for and Google knows this. Hopefully they do something about it sooner rather than later.

  • Alan

    As much as I think ahrefs is a good tool I do block your robot. I have a standard robot blocking list in my htaccess and ahrefs bot is a part of it. Quite frankly I get nothing from your bot hitting my site. What I use ahrefs for is analysing backlinks of my competitors and for that you don’t need access to a site anyway.

  • JulieJoyce

    I can assure you they did not pay for this review. I’ve been using it, I love it, and I thought I’d review it since I’ve been so impressed by it. If they’d paid me to review it I would disclose that information. None of the other tools I’ve reviewed have been paid for either, but occasionally people will ask for a review. In this case no one asked, and certainly no one paid me to review anything.

  • P.T

    I really like Ahrefs as well. However, Ahrefs, please get some UI going and if you offer tools like SEOMoz, you have them beat and my money :-)

  • Henley Wing

    Ahrefs is definitely a tool I will look into. Just curious, how long did the competitive analysis part take roughly? A day, or just a few hours?


    The matter is with the help of robots.txt you are blocking site indexation, but even if you do this, crawlers will still access robots.txt.
    It is done to check whether there were any changes in rules for your domain crawling.
    The query you show was done by our crawler, but it is request to robots.txt. We don’t see any errors on our side in this situation.

  • HackneyMick

    Please make up your mind about whether you observe the robots.txt protocol or not.
    You wrote to me on 22 Oct saying “”Hello! We’ve blocked your site and our bot won’t visit it any more. Sorry for this inconvenience. Regards, Anna (”.
    Today you write, above, referring to my website’s robots file, “with the help of robots.txt you are blocking site indexation, but even if you do this, crawlers will still access robots.txt.”
    Please make up your mind whether you do, or do not, observe the protocols or whether, as I suggested two weeks ago, you are essentially a spamming organisation operating in the world of “bad link building practices”.

  • RedAlkemi

    Wow…some great ideas for sure. Will definitely be implementing some for my own clients…just goes to show that there is such a variety of ways to accomplish the same goal.
