Reading a Backlink Profile
Links from other websites are one of the strongest signals search engines use to judge authority. Here is what each number in the report tells you.
Referring domains
How many different websites link to the domain. Growth here usually matters more than the raw backlink count.
Domain rank
DataForSEO’s 0–100 authority estimate based on the link graph. It is not Ahrefs DR or Moz DA, so compare it only with other results from this tool.
Anchor texts
The clickable text of the links. A natural profile is dominated by brand and URL anchors. Many exact-match keyword anchors can look manipulative.
Broken backlinks
Links pointing at pages on the domain that now return an error. Redirect those URLs to a relevant live page to win the value back.
How to Use
Three steps to see who links to a site.
Enter a domain
Type any domain, e.g. example.com. You can paste a full URL and we’ll use its domain.
Get the profile
We look up the domain’s live backlinks in the DataForSEO index, including subdomains.
Review and export
Check the totals, top anchors and strongest links, then export the link list to CSV.
Use Cases
Competitor research
See which sites link to competitors and how strong those sites are.
Link prospecting
Build an outreach list from the strongest domains linking to similar sites.
Progress snapshots
Record referring domains and rank for your own site to track link building over time.
Link reclamation
Spot broken backlinks and redirect the dead URLs to recover their value.
Frequently Asked Questions
Where does the backlink data come from?
From the DataForSEO Backlinks API, which maintains its own index of links found by crawling the web. No backlink tool sees every link on the internet, so counts differ between providers such as Ahrefs, Semrush, Moz and DataForSEO. Compare domains using the same tool rather than mixing numbers from different ones.
What does the free backlink checker show?
For the domain you enter (including its subdomains) it shows the domain rank on a 0–100 scale, live backlinks, referring domains, referring IPs, broken backlinks, a backlink spam score, when the first link was seen, the top anchor texts, the top linking TLDs, and the 20 strongest referring domains with one example link each. For each link you see the source page, anchor text, dofollow or nofollow, the linking domain’s rank and when it was first seen. You can export the list as CSV.
What is the difference between backlinks and referring domains?
A backlink is a single link from another page to your site. Referring domains are the number of unique websites those links come from. 1,000 backlinks from 10 sites usually count for less than 200 backlinks from 150 different sites. That is why referring domains are often the better measure of a link profile.
What does dofollow vs nofollow mean?
A dofollow link is a normal link that can pass ranking signals to the page it points to. A nofollow link (rel="nofollow", "ugc" or "sponsored") asks search engines not to pass those signals. Google treats it as a hint. A natural link profile has both kinds.
How can I use this to find link opportunities?
Enter a competitor’s domain and look at its strongest referring domains and the anchors they use. Sites that link to several competitors in your niche are good outreach targets, especially if you have a better or more up-to-date resource on the same topic.
Is it free, and are there limits?
Yes, it is free, unlimited and needs no account. There is no daily cap, only a short anti-abuse throttle of 5 checks per minute. Results for a domain are cached for up to 24 hours, so a repeat check may show data from earlier that day.
