LinkCensus vs Ahrefs
Both sit in SEO & marketing. Here is how they differ on the things you can actually check.
LinkCensus
linkcensus.com
Enter a domain and it lists related sites from the historical Common Crawl link graph, which measures proximity rather than direct backlinks, with how many linking sites each shares with yours and, where it can, their names. Results can be narrowed by top-level domain. A free preview shows the first five neighbours without sign-up; a paid seat opens up to 100 rows per lookup with CSV or JSON export, and single-domain reports are sold separately.
Ahrefs
ahrefs.com
A very large link index plus keyword, rank-tracking and site-audit tooling. The reference point for backlink data.
