The Domains Linking to You with a health read on each

Rather than counting links, it counts domains. Each row is one site that has given you at least one link, together with its authority, its link count, its spam score and how long it has held that link.

  • Spam score broken out per domain

The short answer

A referring domain is a single independent site that links to you, no matter how many links it gives. This figure carries more meaning than the total backlink count, because Google too pays more attention to the variety of sources than to the raw number of links.

Always read the link-count column beside the row itself, because that is where the real picture shows. A domain that has given you three thousand links has not given three thousand votes; it put one link in its footer or sidebar and that template repeated across all its pages. To Google this is roughly one link, but it registers as three thousand in the total backlink figure and makes the profile look stronger than it is.

The first-seen date column is useful for diagnosis. If your rankings have dropped, go through the list by that column: several spam domains all added within one week is the signature of a negative link attack, and an old authoritative domain vanishing means that page was deleted or the link taken down. The two cases call for different action.

Do not dismiss the country column either. For a Persian site selling its services in Iran, a link profile that has abruptly filled with domains from countries unrelated to its audience usually means links were bought somewhere, even if you did not buy them yourself and they are a remnant of a previous agency.

The output you receive

The exact meaning of each output column. Read this before your first run so you do not misread a value.

Health
Built from the domain's spam score: below 15 healthy, 15 to 30 acceptable, above 30 hazardous. A high spam score does not equal a penalty; it means the domain's link pattern looks like that of penalised sites.

The data source and method

It rests on the referring-domains endpoint in DataForSEO backlinks. That path is not fixed to a location, so its data is complete for the .ir extension too. What usually takes people aback: on sites inside the country, a large portion of referring domains carry their link in the footer, and one domain sends thousands of links; for that reason, always look at the link count next to the domain count.

The situations where it helps

To assess link-profile quality, or when a ranking drops and you want to know whether fresh spam links arrived or a valuable link disappeared.

Where it falls short

As with any backlink tool, what you see is what the provider's crawler has found, not a definitive list of every link. Very recent links usually have not landed yet. The second thing to know is that this list passes no final judgement on link quality: spam score is a machine estimate, and a domain with a low spam score is not necessarily good for you if its subject has nothing to do with your work. Topical fit is something no column in this table measures, and you have to judge it yourself by opening a few examples.

A lesson from working with it

This endpoint is not location-bound, which makes it one of the few tools in this family with complete data for .ir domains. What usually surprises people is the link-to-domain ratio: on Iranian sites a large share of links are footer links and thousands stem from one domain, so a domain low in the list may in reality be worth more than one at the top with thousands of links.

There is no monthly subscription. You raise the wallet balance, and the price of each run is written on the button before you press it; without a run there is no deduction.

Common questions about this tool

How is this different from backlink analysis?

Backlink analysis shows each individual link with its anchor text; this one stands a level up and gives one row per site. For a quick read on profile quality this one, and for seeing exactly which page linked to you the other one.

Are more referring domains better?

As long as the new domains are real and relevant, yes. A hundred relevant domains beat a thousand irrelevant ones. A sudden, unexplained rise in the domain count is also not what you want, because it resembles the pattern of bought links.

I lost a referring domain, does it matter?

It depends on its authority and fit. Losing an authoritative, relevant domain is worth following up, usually with a simple email to that site. Losing a spam domain is effectively good news.

What you get from Seemerce with Referring domains

Instead of counting links it counts domains: each row is an independent site that has given you at least one link, with its authority, link count, spam score and how long it has kept the link.

Six points on referring domains

We set the pages of three platforms and Google's guidance beside this tool.

1

Domains, not links

Ahrefs shows the number of referring domains apart from total backlinks.

With us Each row is one independent site that has given you at least one link, not a link count.

2

Authority

Ahrefs names Domain Rating and Ahrefs Rank.

With us Rows are ordered by authority.

3

Health of each source

Google says good site-wide signals don't mean all a site's pages will rank well, and vice versa.

With us A spam score is broken out per domain so a risky source can be found.

4

How long a link has been held

Ahrefs has an interactive view of referring domains and pages over time.

With us For each domain it shows how long it has held the link.

5

Coverage of .ir

Global indexes do not focus on Iran.

With us The data is complete for the .ir extension too.
