Quick answer
A backlink is a link from another site to yours. Search engines treat backlinks as a vote of confidence, which is why authority matters.
What it is
A backlink is an inbound link from another website. Search engines use backlinks as one signal of authority and trust. Quality matters far more than quantity: a link from a respected publication is worth more than hundreds from low-quality directories.
Why it matters
Backlinks remain one of the strongest off-page signals. They pass authority, drive referral traffic and help search engines discover your content.
How to use it
- Earn links by publishing original research, tools or commentary worth citing.
- Pitch journalists and bloggers with a clear angle and exclusive data.
- Audit your backlink profile quarterly and disavow toxic links.
Examples
- A SaaS company publishes an annual industry benchmark and earns 40 backlinks in 30 days.
- An e-commerce brand sponsors a podcast and earns a backlink in the show notes.
