How to Use Semrush Toxic Backlinks Checker & Disavow Tool

Google has introduced many algorithmic updates to filter out web pages that build spam backlinks (or toxic links) to increase SERP rankings for keyword positions.

The sad part is toxic backlinks can occur for any website, even on yours unknowingly. Some competitors use shady methods such as automated websites and PBNs (Private Blog Networks) to build backlinks to other sites so that their authority sites outrank them.

As a webmaster, the solution here for you is to find those toxic backlinks and use the Disavow tool in Google Search Console to maintain the quality of your website’s link profile in great shape. (so no matter how others try to build toxic links to your site, your site’s SERP ranking will not impact)

Among many Toxic link checkers, the Semrush Toxic Backlinks finder is one the best.

Semrush is equipped with one of the largest backlinks databases in the world while new backlinks are added every 15 minutes.

  • 17,280,000,000 URLs crawled per day
  • 40,309,000,000,000 total backlinks
  • 1,145,000,000 total referring domains

So, they have got records of every link to your site.

When you audit your site’s backlinks, Semrush categorizes them according to their methods. There are many ways a toxic backlink could occur.

(Note: If you want to analyze backlinks and track their progress you need to use Semrush’s Backlink checker)

Note: You must have an active Semrush subscription in order to audit your website. Open your Semrush free Pro account by clicking the button below. (Semrush Pro normally costs $119.95)

Enter your website domain name and click on the ‘Start Backlink Audit‘ button.

Depending on the size of your site, the auditing timing may vary. Once it’s done, you will get to the Backlink Audit report, where you can see Semrush Toxic backlinks-related details.

As you can see, 4.2% of backlinks are considered toxic domains, and 10.0% are regarded as potentially toxic domains.

Since now you have discovered toxic links, you will have three options:

  1. Whitelist
  2. Move to remove list
  3. Move to disavow list

The Whitelist option lets you whitelist any good backlink you are sure of.

Remove list saves toxic links and helps you contact the webmaster or the website admin to request them remove backlinks from their sites.

Disavow list tells Google directly to remove specified backlinks from your Google Search Console account.

If your site has got a massive number of toxic backlinks, it is not worth your time contacting webmasters to remove links. Sometimes it works, sometimes it does not.

Since toxic backlinks are harmful to your site, the obvious, fastest, and easiest method is disavowing low-quality backlinks from the Google index.

Semrush toxic backlinks checker makes it so easier.

Click on the ‘Disavow’ button and select the domain type. You will have two options: Domain and URL. If you see a pattern of many link farms, it’s better to choose the Domain option.

In the Disavow tab, you can see all the domains you chose to disavow.

Click on the ‘Export to TXT‘ button to download a text file.

Now go to Google Disavow Tool and upload the exported file. If you already have uploaded a disavow file, you need to download the previous file and add its toxic links to the new file.

If you wish to follow the ‘moderate‘ path by requesting the removal of backlinks from website owners, Semrush has facilities for it too.

Select backlinks you want to request removals. Click the ‘Remove‘ and then the ‘Move to Remove‘ buttons.

Semrush broken link checker allows you to find dead internal and external links via Semrush Site Audit. But, the Semrush toxic backlinks tool finds all harmful links from other sites to yours.

Although both (broken links and toxic links) are harmful, you can easily find and fix broken links, even with a free plugin like Broken Link Checker for WordPress. However, it is not the same with toxic links.

Semrush’s Toxic links checker is equipped with many features, and here are the benefits I found on it.

  • A complete toxic link checker tool — Unlike other tools, Semrush has it all. Automated Link audit functionality (A project-based system where you can re-crawl backlinks periodically), domain analysis mechanism, and email outreach setup (no need to use email outreach tools like NinjaOutreach, MailShake, and Lemlist)
  • Download TXT file for Google Disavow tool — Semrush generates a disavow text file based on your selection. No need to manually add data.

Final Words

Maintaining a good link profile, particularly inbound links, is very important in search engine optimization because Google has released many updates (i.e., Google Penguin) to punish websites that have spam link profiles.

Link building is a business nowadays. So is a weapon of competitors to harm your site’s organic performance. A good incoming link can increase traffic and keyword rankings. Also, a bad link can ruin existing rankings too.

If SEO is a big part of your business, you need to clean up low-quality backlinks altogether with the help of a link management tool.
