Five links from one website?
One referring domain.
A referring domain is a website that links to yours. If a blog links to you in five posts, that gives you five backlinks and one referring domain. If five different blogs each link once, you have five of each.

A few details about the results.
Why does the list show fewer domains than the total?
The total counts all the distinct linking domains we have recorded for that website. The list shows up to 20 available examples. It is a selection to inspect, rather than an export of every referring domain.
What does “Observations” mean?
It records a connection between two domains. In the current data, 1 means that connection was recorded. It does not mean there is exactly one backlink between those websites.
Can I see the exact page where a link appears?
This tool returns domains, not the individual pages containing each link. Open a referring website to explore it. A recorded connection can also come from a linked image or script, so it won’t always be an article mentioning the target website.
Where do these counts come from?
We use Common Crawl’s published web data and count each linking domain once. Coverage and collection dates differ between tools, so you may see different totals elsewhere. A newly earned link may not appear yet. Our referring domains guide explains what is included.
