Backlink
A backlink is a link from one website or page to another website or page.
In SEO, backlinks are commonly treated as signals that can influence discoverability, authority, trust, and rankings.
What it does
Backlinks connect one part of the web to another.
They are commonly used to:
- Help search engines discover pages
- Pass signals of relevance or authority
- Refer users from one site to another
- Support brand visibility and referral traffic
- Shape how a site competes in search
Core concepts
Inbound link
A backlink is inbound from the perspective of the page receiving it.
If another site links to your page, that is a backlink to your page.
Quality vs quantity
Not all backlinks are equally valuable.
In practice, relevance, authority, placement, context, and intent usually matter more than raw link count alone.
SEO context
Backlinks are one part of SEO, not the whole thing.
Technical quality, content quality, internal linking, search intent, and site structure still matter alongside backlinks.
Common use cases
- SEO analysis and competitor research
- Link-building campaigns
- Measuring domain or page authority patterns
- Finding referral sources
- Evaluating whether content attracts natural links
Practical notes
- Backlinks can be helpful, neutral, or harmful depending on source quality and context.
- A backlink profile is the broader pattern of links pointing to a site or page.
- Tools such as Ahrefs are commonly used to analyze backlinks at scale.
- Backlinks are useful in SEO, but they should not be treated as the only signal that matters.
