The destination is continuously moving, and just when you think you are nearly there, cue an algorithm update that adds 20 miles of unknown terrain to your journey that then have begin understanding and navigating, all while keeping your frustration under wraps.

So, ensuring you’re on top of your SEO and reviewing it regularly to keep it at its best is crucial.

In this blog, I’ll take you through some of the best SEO audit tools you can use to audit your existing SEO strategy:

What is an SEO audit tool and what is its purpose?

An SEO audit tool is software that provides you with a snapshot of your SEO efforts and the competitive landscape.

Key information about your website’s overall standing can be uncovered within minutes, highlighting areas that are hindering your rankings as well as uncovering areas for improvement.

All of the information from SEO audit tools allows businesses to make informed decisions based on the generated data.

SEO audits are crucial to businesses and help them avoid:

  • Loss of traffic due to a site’s health issues
  • Loss of sales or loss of competitive edge
  • Indexing issues
  • Toxic backlinks

The goal of an SEO audit:

  • Highlight whether your SEO efforts are effective
  • Data comparison of past and present website performance
