A free backlink checker from Backlinko, powered by Semrush data. You enter a URL or domain, and it returns the top backlinks, referring domains, and authority signals. Light on filtering compared to a paid tool, though useful for quick competitor checks or building a sense of a domain's link profile.
How to use it
Open the Backlinko Backlink Checker and find the URL input field.
Paste the domain or specific URL you want to analyze.
Submit and wait for the report to load.
Review the top backlinks with anchor text and source domain authority.
Note the total referring domains and authority score for context.
Export the data manually by copying or screenshotting. The free tool does not support direct export.
