How to Conduct a Link Audit

How to Conduct a Link Audit Like Sherlock Holmes


Feeling the pain of poor SEO efforts in the past? Thanks to Penguin 2.0 andHummingbird, the search game has changed. It’s now more important than ever to find and root out bad links to your site.

Most links are great. But the wrong kinds of links could end up hurting your search ranking. Google Webmaster Tools distinguishes between natural links (inbound links that have evolved organically) and unnatural links (those that have probably resulted from an old link building campaign.)

If you’ve ever helped to create links, they aren’t natural. You have to get rid of them.

What Do Bad Links Look Like?

You need to be able to find these unnatural links. If you can, export the data from your backlink checker into a spreadsheet and look for:

  • links with the same anchor text coming from multiple sites.
  • links from sites that are unrelated to your niche.
  • links from sites with a low pagerank or low traffic.
  • links from article directories or sites that look like link farms.
  • links from link exchanges.
  • paid links (whether in sponsored posts, bios, the sidebar or wherever).
  • links from sites with malware warnings.
  • links from sites that aren’t in the Google index (search for site:YOUR DOMAIN NAME).
  • spammy links in blog comments.

Now that you know what you’re looking for, here are some tools to help you find them.

Here are some tools to help you identify bad links.

  1. Google Webmaster Tools – Google Webmaster Tools is the place where you might first get a warning about the presence of unnatural links to your site. It’s also a great tool for getting more detail on those links. Go to the section of the web interface which shows links to your site (it’s under “traffic”) and you can see and download a sample of the data on inbound links.
  2. The free version of Open Site Explorer will tell you the title, URL, page authority and domain authority of your links. There’s an analysis of top pages, linking domains and recently discovered links. However, this is limited to the first few results. You’ll have to upgrade to the paid version of Moz Tools for unlimited use of the tool.
  3. Ahrefs gives a good breakdown of inbound links according to IP, domain, type of site (such as government or educational), and TLD suffix. There’s also a good breakdown of the types of links (sitewide or not, nofollow/dofollow, redirects, forms and so on). In each case you can click for more information. Data is limited in the free version.
  4. Majestic SEO is another popular link profile analysis tool, showing you types of links,anchor text and even assigning a trust score. It has a free plan for personal use, as well as paid plans.
  5. The SEO Gadget Excel tool works with exported data from Open Site Explorer, enabling you to categorize links.
  6. Pick your own – backlink checking is such an important part of managing your site that there are dozens around, some of them built on the tools listed above, as well as those designed for enterprise users like Link Research Toolsand Raven Tools. Matthew Woodward has a good comparison of some of the key ones and so does SEO Hacker.

WordPress site owners have a range of tools for eliminating bad links. These include:

  • Broken Link Checker – for finding both internal and outbound links that don’t work. These also hurt SEO and are worth eliminating.
  • Wordfence Security – a security plugin that runs a regular scan, identifying links out to sites identified as triggering malware warnings. You can edit those links from within the WordPress dashboard.
  • CommentLuv Link Cleaner – a plugin to get rid of all those dubious outbound links if you’re using CommentLuv on your site.

The Next Step – Remove and Disavow

When you’ve found the links you want to get rid of, you have a few options. First, you can request that site owners remove the links that you no longer want pointing to your site.

Search Engine Watch has a good tutorial on creating link removal requests. It suggests that you send a polite request to the on-site contact email and to the WHOIS contact (unless they’re the same) and that you include a link to the page which has the offending link. This will increase your chance of getting the link removed. Try a service like TaskBullet to help administer your link removal campaign.

Another option is to use a link removal tool like these:

  • Remove ’em, which finds bad links and includes a webmaster contact database for link removal requests. There’s a self-service option priced at $249, as well as a full-service option.
  • Rmoov works with an imported list of links to find webmaster contact information and run and report on a link removal campaign.

In both cases, you should keep track of your link removal efforts, because if your site has suffered a penalty because of bad links, it’s good to be able to show that you really tried to have those links removed.

As a last resort, you should try to Google Disavow Links tool. If you have exhausted all other methods and still have a few questionable links, then hit the red button and upload a spreadsheet with those links. It may take a while, but eventually you should see an improvement in your ranking.

Final Thoughts: Be Patient

The process of removing links is not for the faint of heart. It may take some time for you to hear back from website owners. Depending on the extent of the damage, you may not see results as soon as you would like.

Be patient, and be persistent. Ultimately, this is one of the best decisions you can make for the health of your online marketing.
