The Website Backlink Checker preset returns the full backlink profile of duolingo.com: domain rank, total backlinks, referring domains (total, main and nofollow), broken backlinks, spam score and first-seen date.
A backlink is a single link; a referring domain is a unique website that links to you. One domain can send thousands of backlinks, such as a sitewide footer link, but counts as one referring domain.
The Backlink Checker charges one domain-summary event per domain, $0.15 on the free plan and $0.135 on paid plans, plus a $0.005 actor-start fee per run on every plan. The summary event fires only after data is delivered.
The free Apify plan lets the Backlink Checker run 1 domain in summary mode or 3 domains in check mode per run. Referring-domain lists, competitor gap and monitoring need a paid plan.
The Backlink Checker prices per domain, not per row. Check mode costs $0.015 per domain on the free plan (3 domains per run) and $0.0135 on paid plans (up to 100), plus a $0.005 actor-start fee per run on every plan.
The Backlink Checker's domain rank is a 0–1000 score of the domain's link profile in the backlink index; higher is stronger. The backlink spam score next to it runs 0–100, where higher means a more toxic profile.
The Website Backlink Checker results export as JSON, CSV or Excel, or come back from the Apify API, including run-sync-get-dataset-items for a single request. The actor also works as an MCP tool.
