# Referring domains

> The domains linking to your site, with their authority and link counts.

**Backlinks → Referring Domains** lists every distinct domain that links to you. Where [the backlink list](/backlinks/list) has one row per link, this has one row per **site** — the better view for judging who actually endorses you.

## The table

| Column        | What it is                               |
| ------------- | ---------------------------------------- |
| **Domain**    | The linking domain                       |
| **Backlinks** | How many links that domain points at you |
| **Authority** | The domain's authority score             |

25 rows per page, with a **Filter domains…** box and a total count.

## Reading it

Sort your attention by **Authority** first — one link from a strong domain typically outweighs dozens from weak ones.

Then look at the **Backlinks** column for outliers. A domain with hundreds of links to you is almost always a sitewide placement — a footer, sidebar, or blogroll link repeated across their site. That's one endorsement, not hundreds, and search engines treat it accordingly. It also explains inflated **Total Backlinks** on the [overview](/backlinks/overview).

The healthiest pattern is many domains with a handful of links each. A profile where a few domains supply most of the volume is fragile: losing one relationship costs a disproportionate share of your links.

## Filtering

The filter matches on the domain name only, as you type. Useful for checking whether a specific site links to you, or for grouping by TLD — typing `.edu` shows educational domains.

| **Analyzing backlinks…** — "This may take a minute. The page will update automatically." | A run is in progress; the page refreshes itself                         |
| **No analysis yet** — "Run a backlink analysis first to see referring domains"           | Nothing collected yet; run one from the [overview](/backlinks/overview) |
| **No referring domains found** — "No domains match your current filter"                  | Your filter excluded everything; clear it                               |
