Who we are

Ahrefs is a multinational team with roots in Ukraine and headquarters in Singapore. We are a lean start-up company. We value making meaningful and easy-to-use products. We shift things fast to give our customers what matters most to them, and to keep us ahead of the game. Our motto is "First do it, then do it right, then do it better."

Our history

Ahrefs' history dates back to 2011, when we introduced the first version of Site Explorer after a year of preparation and data mining. Site Explorer disrupted the stagnant field of backlink analysis and kick-started a new round of competition among SEO tool providers. It quickly became one of the world's best backlink analysis tools.

From our humble beginnings, Ahrefs has steadily grown. We started out with a cluster of six servers, and gradually evolved to our current, powerful 60 teraflops system. Today, we update our index with the freshest backlinks on the web every 15 minutes, and the crawler processes up to 5 billion pages a day. That's more than a third of what Googlebot does!
