More about the Backlink Checker
Knowing which other sites actually link to a page matters for two different reasons, understanding your own site's link profile and seeing where a competitor's authority is actually coming from, and neither is answerable just by looking at the page itself, only by seeing who points to it from the outside. This tool analyzes backlinks pointing to any URL, estimating each linking domain's authority and flagging whether a link is dofollow or nofollow, distinguishing a link that actually passes ranking value from one that doesn't. Useful for auditing your own site's backlink profile after a content campaign to see what actually earned links, researching where a competitor's search authority is actually coming from, or checking whether a specific backlink is a dofollow link worth counting on or a nofollow one that isn't.
