What is a backlink?
A backlink is a link from another website to yours; it is one of the strongest authority signals search engines use.
Open this screen in the panelA backlink is a link from a page on another domain to a page on your site. Search engines treat each backlink as a kind of reference: a link from a relevant, trustworthy site suggests your page is worth pointing to. Links between pages of your own site are internal links.
Why it matters
- Backlinks still carry real weight in how Google judges authority. On competitive keywords, the top results usually belong to sites with strong link profiles.
- The raw count means little on its own. How many different sites link to you (referring domains), their quality and their relevance matter far more.
- Links from spam sites don't help; see toxic link.
Where you see it in SEOAsist
The Backlinks page pulls your backlink profile through your DataForSEO account:
| Tab | What it shows |
|---|---|
| Overview | Backlinks, referring domains, nofollow domains, rank, toxic count, 90-day trend, anchor texts |
| Links | Active links with a spam score below 50 (one per domain) |
| Lost | Links present in an earlier sync that are no longer returned |
| Toxic | Links with a spam score of 50 or more, plus the disavow file |
| Opportunities | Domains that link to competitors but not to you |
| Outreach | A contact list for requesting links |
Run the first sync with Sync now; after that it refreshes automatically every Thursday at 03:00 UTC. More: Backlink sync.
Example
This sentence on a furniture blog is a backlink to your site:
<a href="https://examplefurniture.com/dining-table">solid oak dining tables</a>
Common mistakes
- Buying bulk link packages; Google treats them as link spam.
- Looking only at the total backlink count; 1,000 links from one site are worth less than links from 50 different quality sites.
- Not tracking valuable links that disappear. The Lost tab exists for this.
