Backlink

A backlink is a link from another website to yours. Search engines treat links from relevant, reputable sites as votes of confidence, which makes backlinks one of the strongest signals of authority.

When a news site, blog or directory links to your page, that link is a backlink. Since Google's original PageRank algorithm, links have been used to judge which pages are important and trustworthy.

  • Relevance: the linking site and page relate to your topic.
  • Trust: the site is reputable and has its own quality links.
  • Placement: a link within the content, not in a footer or a paid list.
  • Editorial: it was given because your page is worth linking to.

How to earn them

  1. Publish things people want to reference: original data, tools, guides.
  2. Get featured in industry media, podcasts and roundups.
  3. Reclaim unlinked mentions and broken links to your site.
  4. Build relationships with sites in your field.
