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?

    The tools and data are the same. However, Ahrefs' subscribers will have higher data allowances and access to all of our premium tools. In addition, Ahrefs' subscription plans allow you to analyze competing websites (unverified websites).
