A website audit can be an overwhelming and tedious task, but it’s important to conduct this process on a regular basis. Regular website audits allow you to ensure that your website is following best practices for SEO and overall performance.
There are so many tools out there for auditing your website. It can be tricky choosing the right tools for you. Below is a brief description of the best free website audit tools that I have found over the past number of years.
MySiteAuditor
MySiteAuditor is by far my favorite website audit tool for a combination of reasons. The main reason is that we can embed it on our agency site and generate way more leads than our contact form. So it’s great for agencies. What’s also very impressive is that if I can get a page to score over 85%, there’s a good chance it will be ranked on page #1 of Google for the key phrase I’m targeting. So the audit really works well and is in direct alignment with Google’s ranking algorithm.
Another reason I love this tool so much is that it audits specific web pages or landing pages for any targeted key phrase. Many SEO audit tools make the mistake of trying to audit the entire site only, and Google ranks web pages, not websites. Here are a few other reason why I love MySiteAuditor.
• Embed Options (for agencies to generate leads): Yes
• White-label your audits: Yes
• Free version: Yes (unlimited audits)
• Can you audit specific web pages? Yes
• Amount of data: Very good!
• Key phrase analysis: Yes
• Comparison audits: Yes
• Export to PDF option: Yes

Sitechecker
Last but not least, and probably my favourite of the bunch is Sitechecker.pro. You can’t export your results to PDF, but you can run 300 audits per month, and they tell you how to fix your errors. There is a limit to 100 urls pe month, but for most purposes you should be ok.
A really clean interface, and UX makes it a joy to use.

Screaming Frog SEO Spider
Unlike most of the SEO audit tools in this space, Screaming Frog SEO Spider is not really a cloud-based software. Instead, it comes in the form of an installable tool, which then proceeds to crawl through your website while extracting on-site data, auditing SEO problems, and analyzing the results in real-time.
Both digital marketers and website owners can comfortably use it to scrape data from their web pages’ HTML, track their server errors and broken links, analyze meta descriptions and page titles, flag up blocked URLs, as well as identify temporary and permanent redirects.

Marketing Grader
Marketing Grader has been around for a while and is owned by the very reputable company, HubSpot, Inc.

It looks at your blog, social media channels, SEO, lead generation ability. and your mobile site. To me this all still has very much to do with your website’s performance, but I do understand why they went more general with their name.
