Backlinq — SEO Backlink Intelligence

Get domain authority scores, backlink profiles, referring domains, and multi-domain competitor comparisons without paying $1,200/year for Ahrefs or SEMrush.

Backlinq aggregates data from Moz, Open PageRank, and Common Crawl and serves it through a clean API. This Actor wraps all four Backlinq endpoints so you can use them directly inside Apify workflows.
