What do you check for?

    Each time we crawl your website, we look for:

    • <strong>Health Score:</strong> The overall performance of your website based on the number of errors.

    • <strong>Performance issues:</strong> How long your website takes to load, and if it’s slower than it should be.

    • <strong>Technical problems:</strong> If anything’s stopping your pages from appearing and ranking in search engines.

    • <strong>SEO errors:</strong> If you’re facing issues with missing meta tags, duplicate content and more.

Check your website health score, performance issues, technical problems and more.

Frequently asked questions

  • How many websites can I use AWT for?

    You can use AWT on an unlimited number of verified websites.

  • Is there a limit on how many pages I can crawl?

    Yes, you get 5,000 crawl credits per project per month. These credits are only used up when you crawl an HTML page with status code 200, so other URLs like broken URLs, redirects or any non-HTML resources aren't counted.

  • Can I see all my website’s backlinks with AWT?

    Yes, and you can even export up to 1,000 rows per report and 10,000 rows per month. Add to that our vast number of sorting and filtering options, and you should be able to easily distill the most important backlink data.

  • Can I see all my website’s keywords with AWT?

    Yes, we show you all keywords in our index. You can also export 1,000 rows per report and 10,000 rows per month.

  • Can I later upgrade my AWT account to a premium Ahrefs subscription?

    Yes. From your AWT account you can sign up for a premium Ahrefs package (see our <a>Plans & Pricing</a> page).

  • Do I get this as a paying customer of Ahrefs?

    The features in AWT are included in all Ahrefs' subscription packages. For verified websites, you'll get an additional 5,000 crawl credits per month in Site Audit, and some limitations lifted in Site Explorer. <a>Learn more on our Product Blog</a>

  • Are the tools (or data) in AWT any different from those in Ahrefs?
