What we measure
Our backlink checker provides key metrics to understand your site's link profile and authority.
Total Backlinks
The total number of links pointing to your domain from other websites. More backlinks generally indicate higher authority, though quality matters more than quantity.
Referring Domains
The number of unique domains linking to you. 100 links from 50 different domains is typically more valuable than 100 links from 5 domains.
Referring Pages
The number of unique pages that contain links to your site. This shows how widely your content is referenced across the web.
Dofollow Ratio
The percentage of backlinks that pass link equity. Dofollow links help improve rankings, while nofollow links still drive traffic but don't pass authority.
Frequently asked questions
What is a backlink checker?
A backlink checker is a tool that analyzes the links pointing to a website from other sites. It shows you how many backlinks a domain has, where they come from, and whether they're dofollow or nofollow links.
Is this backlink checker free?
Yes, completely free. No signup required, no credit card, no hidden limits. Enter any domain and get instant backlink metrics including referring domains, total backlinks, and dofollow ratio.
Why are backlinks important for SEO?
Backlinks are one of the most important ranking factors. Search engines view links as votes of confidence. Sites with more high-quality backlinks from authoritative sources tend to rank higher in search results.
What's the difference between dofollow and nofollow links?
Dofollow links pass "link equity" and help improve your search rankings. Nofollow links have a rel="nofollow" attribute that tells search engines not to pass authority. Both types can still drive referral traffic.
How can I get more backlinks?
Quality backlinks come from creating valuable content, guest posting, building relationships, and reclaiming lost links. Services like Revised help by acquiring domains with existing contextual backlinks from trusted sources like Wikipedia and Reddit.
