We’re powered by seriously big data
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.
