Free backlink checker
Find out who links to a website, how strong its link profile is and which links carry the most weight.
What it shows
- Domain rankA 0–100 score of link strength, based on the quality and number of linking sites.
- Referring domainsHow many different websites link to the domain. It matters more than the raw number of links.
- Spam scoreThe share of links from sites that look spammy. A high score is worth a closer look, not a panic.
Questions
Why are there fewer links than in Search Console?
No crawler sees every link on the web. Search Console shows what Google knows; this checker shows live links found by our data provider's crawler. Use both.
What is a good number of referring domains?
Compare with the sites that rank above you for your main keywords. The gap in referring domains tells you more than any absolute number.
Are nofollow links useless?
No. They pass less ranking value but still bring visitors and make a link profile look natural.
