A dated view of the web's link neighborhood.
LinkCensus uses open Common Crawl web-graph data. Each edition is dated and immutable.
- Source
- Common Crawl host graph, Nov 2025 to Jan 2026
- Coverage
- 52.9M hosts with at least 8 links, 15.6M searchable
- Not covered
- Small or new domains may be missing.
- Cadence
- New editions may be added when built and validated, but no cadence is promised.
How a neighbor is found.
To find websites related to a domain, enter it in LinkCensus. The result ranks nearby sites from a dated Common Crawl link graph. Where retained shared linkers support a result, you can inspect them to see why the site appeared. The free view shows a small result set; paid access expands the available slice. A nearby site is a research lead, not proof of a business relationship.

Built on Common Crawl, sold as results, never as data.
The data comes from the Common Crawl web graph and host embeddings, used under the Common Crawl Terms of Use. That license cannot be passed on, which sets the boundary of what LinkCensus offers.
What LinkCensus sells
Access to search results and neighborhood reports: ranked related domains with the shared-linker evidence behind each one, plus exports of those result rows.
What LinkCensus never does
It never redistributes the host embeddings, the web graph, the host table or the search index, in any format. Exports and reports contain result rows only. It never runs a language model over crawled content, and search results, reports and exports are never generated by an AI model. The one exception is the free outreach planner, which is labelled as AI-written and reads only result rows the visitor already received.
Retained linkers
For each indexed domain the edition keeps its strongest 200 in-linking domains. A shared-linker count is the overlap of two such lists, so it is a floor, never a total. That is why the interface always says "shared linkers (among top 200 retained)".
Report notes
The one-line note on each report row is a deterministic sentence assembled from that row's own data: the shared-linker count, up to two named linkers, whether the TLD matches, the rank band and a hub flag. The same data always produces the same note.

Domain owners can have a domain suppressed from results, exports and reports after verifying control.
