As crucial as it is to monitor your SEO efforts, doing it manually can take a lot of time and resources. That’s why, sometimes, it can be wise to leave some of the heavy lifting to SEO audit tools designed to automate tedious tasks. With them, you can save precious hours in the day!

However, I know that finding the perfect tool for your website is no easy feat. There are dozens upon dozens available out there, and each one promises to be the greatest. That’s why I decided to compile a list of the 20 best SEO audit tools for you to choose from! There’s a mix of free tools with paid features and paid ones with free trials, so you can pick the one that best adapts to your budget and needs.

Now, without further ado, let’s jump right in!


Why You Need an SEO Audit Tool

Before I begin listing the best SEO audit tools, I want to focus on why you might need one.

These tools allow you to see your website the way Google sees it, so you can detect any problems that may potentially affect your ranking in the SERPs.

Any good audit tool will thoroughly assess all elements that play a part in your website’s ranking, from its content and structure to off-page factors such as backlinks and domain authority.

Additionally, you might know already that Google tweaks its algorithm about 500 times per year. At that pace, it’s impossible for any of us to keep up with the changes and also stay on top of any SEO issues that a website may have. In the long run, choosing an audit tool is an investment that’ll take a weight off your shoulders and save up a lot of time and resources!

It’s time for the fun part! Here’s my list of the best free audit tools (as I mentioned earlier, remember that some of them offer paid plans to get upgrades and more comprehensive features).
