Majestic provides link intelligence and domain metrics in the form of backlink histories, referring domains, anchor texts, keyword search volume, and their own Flow Metrics™, to equip SEOs and marketing professionals with the information to improve their link building and search engine optimization (SEO) strategies.
Majestic has two separate link indexes - the 'Historic’ index, which is refreshed monthly, and 'Fresh’ index, which is refreshed daily. The historic index spans back over more than five years, and allows users to review historic backlink profiles and create reports for custom historic timeframes.
