Get an exhaustive website analysis

Site Audit crawls all the pages it finds on your website – then provides an overall SEO health score, visualises key data in charts, flags all possible SEO issues and provides recommendations on how to fix them.

Have a huge website? Not an issue. Crawl it fast by verifying your domain and tuning the speed settings. Or skip crawling unrelated sections entirely by setting parameters to exclude and/or include certain website sections.

Explore your data any way you want

If you’re a skilled technical SEO who wants to go deeper than pre-defined issues, our powerful Data Explorer puts you in full control of over hundreds of different data points on each of your pages.

Make anything you want out of the data from our crawler – starting with creating custom filters based on numerous parameters, or adding custom issues.

Then tell Site Audit what you want to see. From displaying data on a specific property for a segment of pages to screening it out entirely across every crawled page, Data Explorer does it all.

Note: Ahrefs’ backlink and organic traffic metrics are all integrated and can be enabled for display. No more cross-referencing data; you’ll have all the SEO metrics that you care about in one place.
