AhrefsBot is a <a1>web crawler</a1> that powers the database for both <a2>Ahrefs</a2>, an online data toolset, and <a3>Yep</a3>, a revenue-sharing web search engine. It’s the third most active crawler after Google’s and Bing's, visiting over 8 billion web pages every 24 hours and updating its index every 15–30 minutes.

Our bot indexes fresh, accurate information about websites and their content, and how they link to each other. This data is incredibly useful and can be harnessed in many ways:

• Search with Yep to find top-quality content and all the information you need, all while supporting an alternative search engine that aims to put money in the pockets of your favorite content creators.

• If you’re a website owner, use Ahrefs to analyze your website's structure, content, and backlinks to provide insights into its performance – then optimize it to improve user experience, rank higher in search engines, and get more traffic.

• When it comes to web-scale research, Ahrefs lets you dig into how the popularity of a website or specific topic has changed over time, which websites are linking to what types of content, how many times a brand has been mentioned recently, and so on.
