Abisola Tanzako | Feb 21, 2025

Many professionals rely on tools like Ahrefs for search engine optimization (SEO) and digital marketing. Over 60% of SEO experts use backlink analysis tools like Ahrefs to improve website rankings. Ahrefs offers valuable insights into a website’s online performance with its strong capabilities for backlink analysis, keyword research, site audits, and more.

However, some webmasters worry about its crawling impact on their sites, raising questions about whether to restrict Ahrefs. This article explores the benefits of allowing Ahrefs to access your site, reasons to consider blocking it, and the potential consequences of doing so.

Understanding Ahrefs and its function in SEO.

Digital marketers, content producers, and businesses all use Ahrefs, a comprehensive collection of SEO toolsets. Among other things, it aids in evaluating backlinks, keyword rankings, competitor analysis, and content gaps. Ahrefs has a sizable crawler known as “AhrefsBot,” which scans webpages to collect information for their search engine database.

This is how Ahrefs operates:

  • Backlink indexing: AhrefsBot collects backlink information from websites, which is essential for SEO analysis.
  • Keyword research: It provides information on keyword performance and potential by indexing websites’ keywords.
  • Competition analysis: By crawling rival websites, AhrefsBot provides users with information on their backlink profiles, strategies, and best-performing content.
  • Site audits: By crawling your website, the bot can find SEO problems and recommend fixes that raise your search engine rankings.

One of the most popular tools for people trying to boost their internet visibility through organic search is Ahrefs. This tool collects data about a site’s backlink profile, which SEO experts use to find high-performing content, monitor changes in competition strategies, and locate quality backlinks that could boost search ranks.

However, many website owners wonder if allowing Ahrefs to crawl their sites is worth it. While some consider it a great advantage, others are concerned that it could lead to unwelcome competition or severe stress. This brings up the central question: Should AhrefsBot be blocked?

The reason why some website owners block AhrefsBot.

Although many SEO experts consider AhrefsBot essential, there are several situations in which it could make sense to restrict it. A website owner may decide to restrict AhrefsBot for the following reasons:

  • Server load Issues: If your website is large, AhrefsBot’s regular crawling may strain your server. If your server is not set up to manage many crawlers, your website’s user experience and SEO rankings may suffer. Frequent AhrefsBot crawls can also load bandwidth for websites with limited server resources, mainly if their material is changed often.
  • Privacy concerns: Even if it is done for study and enhancement, some website owners might not want their site data, backlinks, or keyword strategy made public. Blocking Ahrefs is a good idea if you value privacy and do not want other people to access the information on your website. Furthermore, competitors may use the Ahrefs data to identify your strategies, so some prefer to keep that information off-limits.
  • Duplicate content problems: AhrefsBot indexes all content accessible to the public, including blogs, articles, and other content intended for a broad audience. If your website has duplicate content or you are worried about competitors scraping it, you should ban AhrefsBot from accessing it.
  • Competitors analysis: Ahrefs offers comprehensive information on rival websites, including backlink profiles and content tactics. Some webmasters may choose to ban AhrefsBot to prevent competitors from examining their backlink profiles and rankings. Blocking AhrefsBot is a means to protect your brand if you are actively trying to increase your web presence and are worried about competitors copying your tactics.
  • Bandwidth issues: If your hosting plan is limited, letting a bot like AhrefsBot crawl your website often may use up bandwidth and increase your hosting expenses. You can avoid more costs by blocking the bot.

The consequences of blocking Ahrefs.

The consequences of blocking Ahrefs are as follows:

  • Loss of helpful backlink information: Ahrefs’s indexing capability is one of its primary advantages. Blocking Ahrefs stops it from collecting information about your backlinks, which may impact how your website’s link profile is analyzed. Blocking it also prevents others from seeing your Ahrefs backlinks, which may affect your website’s reputation and ranking potential. The backlinks pointing to your website play a crucial role in your search engine rankings, and blocking AhrefsBot means missing out on opportunities to measure and improve this aspect of SEO.
  • Reduced visibility in Ahrefs database: SEO experts utilize Ahrefs’ extensive database to evaluate the online competitive environment. If you block your website, it will not be listed in AhrefsBot’s database. Thus, you cannot use their data for competitive analysis, link-building chances, and keyword rankings. Being visible in Ahrefs’ database is crucial for backlink research, benchmarking, and competitor tracking in the SEO space.
  • Diminished competitor insights: You lose access to competitor data when you block AhrefsBot. The ability to view the keyword ranks and backlink methods of your competitors is one of Ahrefs’ primary benefits. You may lose access to this data if you block the bot, which could affect your SEO strategy. You can improve your tactics to rank higher by learning what works for your competition, including which websites connect to them.
  • Limited insights on SEO performance: Ahrefs is frequently used to perform site audits and find problems that could lower your rankings. However, Ahrefs cannot perform these audits if it cannot crawl your website, which could cause you to miss important information about possible SEO issues.
    Site audits are essential for optimal SEO because they can spot problems impacting rankings, such as broken links, missing meta tags, or slow-loading pages. Blocking AhrefsBot means sacrificing the convenience of regular audits by a trusted SEO tool.

The advantages of letting Ahrefs crawl your website.

There are good reasons to let AhrefsBot crawl your website and good reasons to ban it. Allowing Ahrefs access to your website has the following advantages:

  • Better SEO performance: AhrefsBot assists SEO experts in identifying and resolving website problems. During site crawling, it can identify areas that require repair, such as broken links, sluggish loading speed, or missing meta tags.
  • Essential backlink data: AhrefsBot collects information about backlinks that lead to your website. You can acquire this information by letting AhrefsBot crawl your website, which is crucial for enhancing your link-building tactics. Ahrefs provides information about which websites link to you and which you can use to guide your content production and outreach tactics. Developing a solid backlink profile is essential for SEO success, and AhrefsBot assists in spotting possible dangers and possibilities within your backlink ecosystem.
  • Competitor analysis: You can use AhrefsBot to collect competitor data and analyze competitors’ SEO tactics, backlink profiles, and content performance.
  • Keyword research and insights: AhrefsBot crawls web pages to provide keyword rankings and performance information. By letting AhrefsBot crawl your website, you can gain insight into your keywords’ performance and possible chances to rank for more terms.
  • Finding content gaps: By indexing your website’s content, AhrefsBot helps you identify gaps where you may miss out on keyword opportunities. By examining this data, you can produce more pertinent and focused content to satisfy your audience’s demands.

How to turn AhrefsBot on or off.

If you have made that decision, you should know how to appropriately restrict or allow AhrefsBot on your website. You can control AhrefsBot’s access to your website in the following ways:

  • To enable AhrefsBot, leave your robots.txt file empty of any blocking restrictions. This will give the bot unrestricted access to your website.
  • To disable AhrefsBot from crawling your website, add ‘disable’ to your robots.txt file.

The question is, is it wise to block Ahrefs?

No, Blocking Ahrefs is generally not wise because it offers valuable SEO insights, including backlink data, keyword rankings, and competitor analysis, which help improve your website’s performance. However, yes, if you are concerned about data privacy, server load, or competitors analyzing your site, restricting AhrefsBot might be beneficial.

Before deciding, consider the trade-offs; blocking Ahrefs means losing access to critical SEO metrics that could impact your ranking strategy. On the other hand, allowing it can provide essential data to refine your digital marketing efforts. Ultimately, the best choice depends on your website’s objectives, security concerns, and SEO priorities.
