What Are Backlinks?
A backlink is any hyperlink on an external website that points to your domain. Search engines like Google treat backlinks as “votes of confidence” — the more authoritative sites that link to you, the more Google trusts that your content is valuable, which improves your rankings in search results.
Not all backlinks are equal. A single link from a high-authority news site (e.g. BBC, TechCrunch) carries far more weight than hundreds of links from low-quality directories or spam blogs.
Dofollow vs Nofollow
| Type | HTML attribute | Passes “link juice”? | Notes |
|---|---|---|---|
| Dofollow | (none, default) | Yes | The standard — boosts target page authority |
| Nofollow | rel="nofollow" | No | Added by sites for user-generated content (forum posts, comments) |
| Sponsored | rel="sponsored" | No | Required by Google for paid/affiliate links |
| UGC | rel="ugc" | No | User-generated content: reviews, forum answers |
