Website Authority Checker
Type a domain, get its authority profile: Domain Rating, how many sites link to it, total backlinks, and its organic search footprint. Size up your own site, a competitor, or a prospect before you pitch.
Domain Rating (DR)
The strength of a site's backlink profile on a 0–100 scale. It's logarithmic: climbing from 40 to 50 is much harder than from 10 to 20.
Linking sites (referring domains)
Unique websites that link to the domain — for link building, the number that matters most. A thousand links from one site move you less than ten links from ten sites.
Backlinks
Every individual link, including many from the same site. Big numbers here are cheap; unique linking sites are not.
Organic traffic & keywords
An estimate of the search visibility all that authority actually buys.
Raise the numbers, don't just watch them
Checking authority is diagnosis. The cure is earning links from real sites in your niche — exactly what the BacklinkGPT agent does, with your approval on every send.
