Link data from the seotools.pro backlink index
Ranked by referring-domain authority
No signup and no card
Every column, no field held back
Backlinks, domains, follow split, IPs, subnets, trust
Domain to link profile in three steps.
One check queries the seotools.pro link index and returns the profile plus the strongest links on one screen.
moz.com or https://www.moz.com/blog
Enter any domain
Paste a bare domain or a full URL. We strip the protocol, path and www for you.
Usually 5 to 25 seconds
We query the link index
The profile totals arrive first, then the individual links, so you can start reading immediately.
50 links per free check
Read the profile
Sort by authority, open any referring page, and see the anchor and first-seen date behind every link.
What each number actually means.
Every metric in the results, its scale, and how to act on it, so you read the profile like an SEO rather than a tourist.
| Metric | Scale | Source | How to read it | What to do with it |
|---|---|---|---|---|
| Backlinks | Count | seotools.pro link index | Every individual link pointing at the domain, including many from the same site. | Compare against referring domains: a high ratio means few sites linking a lot. |
| Referring domains | Count | seotools.pro link index | How many distinct websites link to the domain. Usually the more meaningful number. | This is the figure to track month over month, not raw backlinks. |
| Dofollow / nofollow | Count + share | seotools.pro link index | The split across the whole profile, not just the links shown in the table. | A profile that is almost all nofollow passes far less authority than the total suggests. |
| Referring IPs | Count | seotools.pro link index | Distinct IP addresses hosting the linking sites. | Far fewer IPs than referring domains can indicate links from one network. |
| Referring subnets | Count | seotools.pro link index | Distinct class-C subnets behind the linking sites. | The stricter version of the IP check for spotting link networks. |
| Domain trust | 0 to 100 | seotools.pro Domain Trust | The seotools.pro authority score for the domain. Not Moz DA or Ahrefs DR; the scales differ. | Use it to rank link opportunities against each other, not as an absolute grade. |
All metrics come from the seotools.pro link index. When the index has no record for a domain we say so, and any metric it does not report shows as "—" rather than as a zero.
The profile numbers, not just a link list.
Most free backlink checkers show a handful of links and hide the totals. This shows both.
The whole-domain picture before you look at any single link.
Backlinks and referring domains
Both totals for the entire profile, so you can see how concentrated the link graph is.
Referring IPs and subnets
The network-level view that shows whether many domains share one host.
Built for the moment before you pitch.
A link profile answers questions that a traffic estimate cannot.
Sizing up a competitor
See how many distinct sites link to them and how strong those sites are before you plan a campaign.
Vetting a link opportunity
Check a prospect's own profile so you know whether a link from them is worth the outreach.
Auditing a site you inherited
Find out what the existing link profile looks like before you touch anything else.
Reporting to a client
Pull referring domains and the follow split as a baseline you can measure against next month.
How this differs from other free checkers.
Free backlink checkers usually show a few links and hide the totals behind a signup. Here is the split, including what we do not do.
| Typical free checker | Free tier of a paid suite | seotools.pro |
|---|---|---|
| Profile totals without an account | ||
| Follow split taken from the whole profile | ||
| Domain authority on every individual link | ||
| States the sample size next to the total | ||
| No email gate on the results | ||
| Says plainly when it has no data for a domain | ||
| Historical lost-link tracking |

Backlink checking, answered.
Is this backlink checker really free?
Free, no signup
Yes. Three checks a day with no account, no card and no email gate. The limit is enforced on our server, so it is the same number whatever browser you use.
Where does the data come from?
Totals for the whole profile, top 50 links
The seotools.pro backlink index. We query it on the first check of a domain and cache the answer for seven days, so repeat lookups are instant.
Why did my domain come back with no data?
50 links per check
Either the index has no record of it or it has no indexed inbound links yet. Those two look identical from the API, so we say only that we found no data rather than guessing which it is.
Stop guessing who links to them.
Run your first backlink check now. Free, no signup, totals and top links on one screen.
