CrawlGraph

About CrawlGraph

CrawlGraph is a backlink research tool that indexes Common Crawl data to identify sites linking to a given domain. Users paste a competitor's URL and receive a list of referring domains, ranked by a proprietary "CG Authority" metric based on harmonic centrality within the Common Crawl graph. A gap analysis feature compares up to 3-4 competitors side by side to surface matching referring domains, and results can be broken down by top referring domains and TLD.

The free tier returns 5 results per query with no signup required. A one-time $99 payment (listed as a launch price, increasing to $149) unlocks the full referring-domain list, CSV/JSON export of up to 100,000 referring domains per query, access to queryable Common Crawl releases, and a REST API (bearer token authentication) with a starting allowance of 15 free backlink lookups per month before paid plan limits apply. An optional $5/month add-on ("SEO fix") emails a single recommended backlink task per month; it requires the paid core plan and can be paused or canceled from the dashboard.

The product is positioned for outreach-based link building rather than continuous rank tracking or monitoring, contrasting itself with subscription-based competitors (Ahrefs, Semrush, Moz) that charge monthly fees. It targets users doing manual backlink outreach - identifying sites that link to competitors and contacting them - rather than users seeking automated or continuous SEO monitoring; the site states no SEO expertise is required to use it.
