What is Backlink?

A backlink is a link to your site from another website. Links from trusted, relevant sites are one of the strongest ranking signals.

Updated

A backlink is a link from another website to yours. Search engines treat links as votes of confidence, so links from trusted, relevant sites help a page rank.

Quality over quantity

One link from a respected site in your field is worth far more than hundreds from low-quality ones. Spammy or paid links can do harm.

How sites earn them

  • Useful content others want to cite: original data, thorough guides, free tools.
  • Being the source: research or statistics people reference.
  • Outreach: sharing a genuinely useful resource with people it helps.
  • Digital PR, partnerships and being quoted.

What to avoid

Buying links, link exchanges at scale, and automated link building. They violate search engine guidelines.

Attributes

A link can carry rel="nofollow", sponsored or ugc to tell search engines not to treat it as an endorsement.

Free tools and original, well-sourced articles are among the most reliable ways to earn links naturally.
