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.

Watch the crawl of your website in real time.
See all relevant data at a glance with multiple charts.
Check against 160+ pre-defined SEO issues with your domain and get recommendations on how to fix each one.
Clicking on any issue shows you a list of the URLs affected.

Check your website for 160+ pre-defined SEO issues

Site Audit automatically groups issues by type and pulls printable reports – all fully visualized with colored charts.

Check for issues related to:

  • Performance: slow pages, too-large CSS or HTML

  • HTML tags: missing, duplicate or non-optimal length of title tags, meta descriptions and H1 tags

  • Social tags: incomplete or missing Open Graph tags and Twitter cards

  • Content quality: low word counts, unconsolidated duplicate pages

  • Localization: all issues with Hreflang

  • Incoming links: detecting orphan pages, issues with nofollow links

  • Outgoing links: detecting links to redirects, broken pages

  • Resources: issues with images, JavaScript, CSS

  • External pages

  • And more!

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 a hundred 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.

With Data Explorer, you’re a simple click away from seeing every detail of each specific URL. This includes incoming and outgoing links, hreflang, pagination, duplicates and resources.

Ahrefs’ Site Audit is entirely cloud based. That means:

  • No need for installation

  • Mobility of data – log in anytime for access, wherever you are

  • No processing costs on your end

  • Automatic save of each crawl

  • Automatic software updates

Execute JavaScript while crawling

Ahrefs’ Site Audit can render JavaScript-generated content on any website page (depending on your pricing plan)

JavaScript execution lets Site Audit analyze pages and links that depend on JavaScript, resulting in the most accurate audit. This is especially valuable for sites using JavaScript frameworks such as Angular or React. Learn why this is important.

Crawl a mobile website
