If you’re searching for the best SEO audit tools, you’ve stopped at the right page.

Google uses several algorithms and ranking factors to retrieve data for a particular search query and rank the most relevant pages on the SERPs. Things get even more complicated when Google Algorithms changes 500 to 600 times per year — meaning that most of these tweaks are so minor that the users may overlook them.

When Google makes thousands of algorithm changes and uses more than 200 ranking factors, SEO tools become essential to keep up with these updates and maintain top keyword rankings.

Meanwhile, SEO auditing plays a significant role as it crawls your websites and pinpoints technical SEO issues such as broken links and slow page load — everything that harms SEO health.

After all, SEO audits give you actionable insights into improving the search rankings and save you from battling the intricate SEO mechanisms.

Some of the best SEO audit tools you should not miss are Semrush, Serpstat, and Seobility.

In this article, we’ll walk you through 10 of the best SEO audit tools.
