Ahrefs Backlink Explorer SEO Tool

Ahrefs offers a limited free trial of its backlink checker, which lets you see some of the best backlinks (but doesn't go into any detail). With a database of 25.86 trillion, Ahrefs provides fairly accurate metrics and allows you to analyze your competition. Ahrefs lets you see your domain's rating, the total number of backlinks and referring domains, and the keywords they're ranked for. You can identify broken or deleted backlinks. Ahrefs offers metrics known as Domain Rating (DR) and URL Rating (UR) to gauge how good a backlink is. You can also see their movement. Ahrefs allows you to generate a Referring domains report. It consists of a list of all domains, their Ahrefs score, organic traffic, and targeted links.
