Ahrefs, founded in 2010, built its reputation on backlink data specifically, maintaining one of the largest and most frequently updated backlink indexes in the industry, and has since expanded into a full SEO suite covering keyword research, site audits, rank tracking, and content exploration under one login.
That breadth and depth, more than fifteen years of continuous data collection, positions Ahrefs as the established, comprehensive option in a category full of newer, narrower tools: an agency or in-house SEO team managing numerous different tasks across dozens of sites tends to gravitate here specifically because most of what they need already lives in one platform rather than several.
There's no free plan; pricing starts around $129 a month. For an SEO professional or agency that wants deep backlink data alongside a full suite of other SEO tools in one place, rather than a narrower tool focused on a single task, Ahrefs' comprehensive scope and long operating history address that breadth directly.
