Free Backlink Checker — Analyze Any Domain's Link Profile
Backlinks are one of Google's most important ranking signals. A page with high-quality backlinks from authoritative websites ranks higher than a similar page with few or no links. This free backlink checker lets you analyze the link profile of any domain, see referring domains, examine anchor text distribution, and identify the types of links pointing to a site.
Enter any domain to see its backlink data. You can use this tool to analyze your own site's link profile, research competitors, identify link-building opportunities, and find potentially harmful links that may be affecting your rankings.
Understanding your backlink profile is essential for any SEO strategy. Without knowing who links to you and how, it is impossible to build a coherent link-building plan or diagnose why a site is underperforming in search results.
Why Backlinks Matter for SEO
Google's original PageRank algorithm was built on the concept that a link from one page to another is a vote of confidence. Pages with more high-quality votes rank higher. While Google's algorithm has grown far more complex, backlinks remain one of the top three ranking factors alongside content quality and RankBrain signals.
Authority transfer. A link from a trusted, high-authority website passes ranking power (link equity) to the linked page, boosting its ability to rank.
Discoverability. Backlinks help search engine crawlers discover new pages. Without incoming links, a page may not be found and indexed by Google.
Trust signals. A site with links from reputable publications, government websites, and educational institutions is seen as more trustworthy than a site with no such endorsements.
Competitive advantage. In competitive niches, backlinks often separate the top-ranking pages from those stuck on page two. Building more and better links than competitors is a direct path to higher rankings.
What to Look for in a Backlink Profile
Referring domain diversity. Links from many different domains are more valuable than many links from the same domain. A healthy backlink profile includes hundreds or thousands of unique referring domains.
Anchor text distribution. Natural link profiles have diverse anchor text — branded anchors, naked URLs, generic phrases like "click here," and some keyword-rich anchors. Profiles dominated by exact-match keyword anchors are a red flag for manipulation.
Link quality. Links from high-authority, topically relevant sites carry more weight than links from low-quality directories or unrelated sites.
Toxic links. Backlinks from spammy, penalized, or irrelevant sites can harm rankings. Identifying these allows you to disavow them using Google's Disavow Tool.
