Why backlinks still matter
Links from other websites remain one of Google's strongest ranking signals: each relevant link is a vote of confidence. What counts is quality, not quantity. One link from a respected site in your industry beats hundreds from low-quality directories.
Checking a competitor's backlinks shows where their authority comes from: industry sites, partners, press or resource pages you could approach too.
Tips for using the backlink checker
Look for patterns
Directories, partner pages or press that link to competitors are often open to linking to you too.
Quality over quantity
One link from a respected site in your niche beats dozens from unrelated directories.
Fix broken backlinks
If sites link to pages you've moved, redirect them. Test old URLs with the redirect checker.

Backlink Checker FAQ
Where does the data come from?
From DataForSEO, which supplies search volumes from Google Ads data and live Google results to SEO tools worldwide. Every figure is real; when there's no data for a query, the tool tells you instead of guessing.
What's a referring domain?
A unique website linking to you. Ten links from one site count as one referring domain, and referring domains matter more than total links.
Is it free?
Yes. Search-data tools are limited to 5 runs per person per day because each lookup costs us real data credits. Rankfly customers get this research done automatically for their whole site.
What's the difference between dofollow and nofollow links?
Dofollow links pass ranking value; nofollow links ask search engines not to. Both can bring visitors.
How many backlinks do I need?
There's no number. Compare referring domains with the sites ranking for your keywords.
Are all backlinks good?
No. Spammy, paid or irrelevant links don't help and can hurt. Focus on genuine, relevant ones.
