Siamo alimentati da big data davvero grandi

Ahrefs collects, processes, and stores large amounts of data for search marketing professionals.

Similar to search engines, we crawl the entire web 24/7 and store petabytes (1PB = 1000TB) of information about live websites – like how they link to each other and what keywords they rank for in search results.

We're also really proud of our backend infrastructure. Since no existing solution could keep up with the volume of data we operate, most of our software infrastructure was built in-house.
