How Does AhrefsBot Work?

AhrefsBot operates as a web crawler, similar to other search engine bots like Googlebot or Bingbot. As per the Bot Traffic Report from Imperva Incapsula, AhrefsBot stands out as a highly active web crawler employed by businesses for website crawling and data retrieval in the realm of digital marketing.

Its continuous operation is dedicated to providing online marketers with an enhanced understanding of search engine indexing and ranking algorithms, including those of Google, Yahoo, and Bing. This persistent effort enables marketers to refine their websites and optimize SEO campaigns more effectively. Here’s an overview of how AhrefsBot works:


AhrefsBot starts by crawling the web, visiting websites, and requesting pages from their servers. The AhrefsBot crawls more than 6 billion web pages every 24 hours and updates the link index every 15-30 minutes. During the crawling process, it follows links on pages to discover new content. The goal is to build a comprehensive index of web pages.

Discovering New Pages:

AhrefsBot identifies new pages by following links from known pages in its index. This allows it to discover and index fresh content as it becomes available on the web.

Data Collection:

As AhrefsBot crawls pages, it collects data on various SEO-related metrics, including but not limited to:

      • Backlinks: AhrefsBot identifies and records information about backlinks to a particular page, such as the linking domain, anchor text, and more.
      • Keywords: It analyzes the content of pages to understand the keywords they are targeting.
      • On-Page SEO Elements: AhrefsBot may also collect data on on-page elements like meta tags, headers, and other factors that contribute to SEO.

Site Audit:

AhrefsBot is involved in site audits, where it systematically analyzes websites for common SEO issues such as broken links, duplicate content, missing meta tags, and other on-page and technical SEO issues.


The data collected by AhrefsBot is then processed and indexed in the Ahrefs database. This indexed data is what Ahrefs users can access through the Ahrefs platform to gain insights into their own websites and those of their competitors.

Regular Updates:

Ahrefs Bot regularly revisits websites to update its index with new data. This ensures that Ahrefs users have access to the most recent information about their site’s performance and that of others in their industry.

Respect for Robots.txt and Noindex Meta Tags:

AhrefsBot, like other web crawlers, respects the rules set by websites through the robots.txt file and meta tags like “noindex” and “nofollow.” If a website instructs AhrefsBot not to crawl certain pages or sections, it will adhere to those directives.

It’s important to note that Bot is a tool used by the Ahrefs platform to gather data for SEO analysis, and it is not a search engine itself. The data it collects is made available to users through the Ahrefs interface, helping them make informed decisions about their website’s SEO strategy.

Managing AhrefsBot Access on Your Site

AhrefsBot is the web crawler used by Ahrefs, a popular SEO tool, to index and analyze web pages. If you want to manage AhrefsBot’s access to your site, you can do so by using the robots.txt file on your server. The robots.txt file is a standard used by websites to communicate with web crawlers and other web robots.

Managing AhrefsBot Access on Your Site

Here’s how you can manage AhrefsBot access:

Create or Edit robots.txt:

Open your website’s root directory on the server.

Look for a file named robots.txt. If it doesn’t exist, you can create one.

If it already exists, open it in a text editor.

Allow AhrefsBot:

To allow Ahrefs Bot access, add the following lines to your robots.txt file:

User-agent: AhrefsBot
Allow: /

This indicates that AhrefsBot is allowed to crawl all parts of your site.

Disallow AhrefsBot:

If you want to disallow Ahrefs Robot from crawling certain parts of your site, you can use the Disallow directive. For example:

User-agent: AhrefsBot
Disallow: /private/

This would prevent AhrefsBot from crawling any URLs that begin with “/private/.”

Wildcard Usage:

You can use the wildcard * to apply rules to all bots. For example, to disallow all bots from crawling a specific directory:

User-agent: *

Disallow: /restricted/


After making changes to the robots.txt file, it’s a good practice to test it using Google’s robots.txt Tester in Google Search Console or other online tools. This helps ensure that the syntax is correct and that it will be properly interpreted by web crawlers.

Regularly Update:

Keep in mind that search engine bots may update their user-agent strings or behaviors. It’s a good idea to check Ahrefs’ documentation for any changes and update your robots.txt accordingly.

Remember that the robots.txt file relies on the honor system, and well-behaved bots will generally respect the rules you set. However, it’s not foolproof, and malicious bots may ignore these directives. If you have more advanced needs or concerns, you may want to consider other access control methods, such as using meta tags or HTTP headers.
