71 Technical Factors For Backlink Analysis (From 30 Link Building Experts) – Part 2
Welcome to part 2 of our 3-part group interview series on backlink profile analysis. Part 1 covered backlink analysis for link building campaign design. Part 2 covers the more technical aspects of analysis, and what elements that link building experts look at to gauge the overall strength of a backlink profile.
14 URL factors in backlink profile analysis
The URLs of linking pages can tell you a great deal about a given site’s backlink profile. The URLs themselves can shed some light too when evaluating the quality of a given link prospect. Some of the link builders interviewed didn’t place value in URL analysis when investigating backlink profiles. Some did. Often, this comes down to differences in style and process.
- TLD (if .govs or .edus have been linking it can indicate high-trust, high-value content)
- Target keywords in the URL
- Target keywords in the hostname
- Number of URL parameters
- Depth of the page on the site (as measured by /’s)
- Iterations of ? and other extraneous characters
- Excessive hyphens in a URL can indicate over-SEO’d content
- URLS on blogspot or wordpress
- Avoid https:// and ftp://
- “links4free,” “getfreelinks,” etc…
- The words “review” or “advertorial” (can indicate paid posts)
- The linked-to site mentioned by name in the URL (can indicate a paid review)
- Words that indicate content types (ie: “blog,” “news,” “forum,” etc…)
- Excessive amounts of links.html and links.php indicates a weak profile
Key comments on URL factors
“Anything that indicates a news and information site is high on my list.”
-Ken McGaffin, of WordTracker
“It is not something I spend time on. It is nice if their URL has keywords in it, but the link is valuable with or without that being the case. Other factors matter much, much more.”
–Eric Enge, Stone Temple Consulting
“When reviewing URLs, one strict but useful criteria is to scrutinize any website that uses hyphens in conjunction with keyword phrases in their domain name. A little SEO knowledge can sometimes be like a sharp stick in the hands of a child. Hyphenated domain names can be an indicator that a webmaster is running around with a sharp stick.”
-Roger Montti, aka MartiniBuster
“I’m looking for the presence of target keywords in file paths and names and at TLDs. I’m also looking to see if there’s an opportunity to purchase a similar domain name (in the case of exact match), with an alternate TLD.”
-Ken Lyons, of Wordstream
“Even an ugly URL can get indexed, but you want to make sure that it’s the canonical URL for that page and that your link didn’t wind up on some duplicate page. It’s also preferable when the URL structure is clean and uses descriptive phrases.”
-Jennifer Van Iderstyne of Search Slingshot
“To me, if a page is quality (i.e. relevant, has PR, dofollow, ranks well etc), then I don’t really care what the URL is.”
-Melanie Nathan, Canadian SEO
“I look for things like keywords in the URL (more is good), URL parameters (fewer is good), and the depth of the directory (fewer slashes is good).”
-Jeremy Bencken, of WebSimple
29 on-page factors in backlink profile analysis
When investigating backlink profiles, it’s vital to look at the pages that contain (or will contain) the link. Link builders consistently cited on-page analysis as a crucial element of backlink profile analysis.
- Link embedded within relevant content that discusses link target
- Title, headers, and content to see if the theme of the page is on topic
- Text surrounding the link
- Does the link appear paid or given freely, by editorial choice?
- Does the page rank for its title?
- Spam content in comments
- The anchor text of the link
- Page linked from other external websites
- Proximity of the page to the root location
- How well the page is linked to from within the website
- The URL being Linked To (home page or deep)
- Location of the link (on the page)
- Number of outbound links on the page
- Page Content (topic and amount)
- Page back links
- Page cache date
- Quality of outbound links
- Logical, appealing page layout
- Page is bot-readable
- Title and HX tags present?
- Important page on the site vs. a “throw-away” blog post
- Can you add directly to the discussion
- Excessive advertising
- Excessive links from link directories or blogrolls
- Excessive links from links.php pages
- Duplicate links on the same page (what is the first link’s anchor text?)
Key thoughts regarding on-page factors
“On page criteria is integral to the backlink analysis process. Outbound links are critical. It’s important to do a double backlink analysis. Analyze the backlinks of the sites your link candidate is linking to. This will help determine exactly what kind of link clique you are going to be associated with. Building a link clique independent from established link cliques is a way of combatting the established 800 pound gorillas that are entrenched in the top three. When you study the backlink of established sites you will generally see a relevancy pattern. Poaching from their backlinks only makes you a part of their sphere of influence. In my way of doing things, I aim to establish my own, and it has worked in overtaking websites that are a part of multi-million dollar networks for important two word keyword phrases. On page criteria is a key part of this process.
The ideal web page, in terms of on page factors, is a web page that has zero SEO fingerprints. Zero.”
“In general, I prefer to see a fairly decent pagerank (1-3 depending on how far down the page is in the site architecture) with a good amount of both external and internal links (can’t stress this point enough). Obviously relevancy is a must, but a more telling signs of a pages’ authority is its cache date; within one week is great, 1-2 weeks is average, 2-3 weeks is just OK, and anything 3+ weeks isn’t very powerful.”
-Paul Teitelman, of Search Engine People
“The page must be closely geared towards my client’s target term or I don’t even bother. I want prospects where I don’t have to convince them to link; they just do it because it’s a logical fit. ”
“A neat tool for quickly analyzing the value of getting a link once you’re on a page is Foxy Rank”
-Tom Demers, of WordStream
“Is the link in the middle of content on the middle of the page, if not, take that into account. What other links are around it? Where do all the external links point out to on the page as a whole, are they relevant destinations to your site? Was this link added to the page after the fact or did it show up when the page was created?”
-Brian Chappell, of Adapt Marketing

Key insights regarding on-site factors
“I look for evidence of human activity. I’ll want to see who writes the content and how dedicated to the task they are. I’ll also look at evidence of audience participation – do people leaves comments on articles for example. Once I’ve established in my head that it’s a quality site, I’ll look for opportunities such as ‘write for us’, ‘submit an article’, ‘editorial guidelines’, etc. I’ll also look for partnership opportunities with sites I’m really taken with.”
“We look at the website’s linking profile and overall strength of backlinks. Specifically, we look at deep links within a website we’re trying to acquire a link from for our client. If the homepage is very strong and the site has no deep links, then the value is typically lessened. The structure of the website and how strongly focused it is to the client’s business is the next best indicator for us. Is it easily spidered and indexed by Google. A quick way to see this would be to type in “site:widgetsite.com,” then look at not only the pages indexed, but also pay attention to the diversity of the title tags, descriptions, and URLs being indexed in Google. Stronger websites nearly always have a wider and more clear diversity while previewing the indexed pages from the website.”
-Brian Gilley, of Social SEO
“A lot of the link stuff is recursive. So when you look at an individual page or site that someone is getting a link from sometimes you can also see where that site is getting links from and come up with new link building ideas based on that.”
