About the Backlink Checker

Returns linking domains and link counts for a site through the Moz index, with the anchor text and authority of the referring pages where available.

No free tool sees the whole web. Every backlink index is a crawl of a subset, and the subsets differ, which is why two tools report different numbers for the same site and neither is lying. Treat the output as a sample that shows patterns rather than as a complete ledger.

The pattern to look for is concentration. A profile where most links come from one network, one directory dump or one guest-post cluster is fragile, because a single change on their side removes the lot. Diversity of source matters more than the count.

Common questions

Why do different backlink tools show different numbers for the same site?

Every backlink checker, including this one, indexes a crawled subset of the web rather than the entire internet. Different crawlers see different subsets, so disagreement between tools is normal, not an error.

Is more backlinks always better?

No — a link profile concentrated in one network or one source is fragile, because losing that single source removes a large share of your links at once. Diversity of source matters more than raw count.

Does this tool find backlinks in real time?

No tool does. Results reflect the most recent crawl of the underlying index, which may be days or weeks old depending on how frequently that part of the web was last visited.
