Backlinks: The Complete Guide
What Are Backlinks?
Backlinks, also known as inbound links, are hyperlinks from one website to another. They act as signals of trust, showing that one site finds another site’s content valuable. Search engines like Google interpret backlinks as “votes of confidence,” which help determine a page’s authority and relevance.
For example, if a British hedgehog website links to a hedgehog sighting map as a helpful resource, the map receives a backlink. These links are usually blue and underlined, though styling may vary. Hovering over them displays the destination URL in the browser.
Backlinks remain one of the strongest ranking factors in SEO because they help search engines measure credibility, distribute authority, and discover new content.
Why Are Backlinks Important?
Backlinks serve several critical roles in SEO:
- Signal authority and relevance
Search engines rely on backlinks to evaluate credibility. A page with authoritative sites linking to it is seen as more trustworthy. Google’s PageRank algorithm originally measured this value, and the principle still applies today. - Improve rankings
Pages with more high-quality backlinks typically rank higher. For example, competitive keywords like “pram for triplets” often show top-ranking pages with numerous backlinks. - Earn referral traffic
Links from authoritative sites not only aid rankings but also drive direct visitors. A backlink from a publication like Harvard Health can send readers directly to your site. - Build Domain Authority
A strong backlink profile helps increase a website’s Domain Authority, a metric estimating ranking potential. - Help with crawling and indexing
Search engines follow backlinks to discover new content, making links essential for indexing. - Competitive analysis
Examining competitors’ backlink profiles reveals opportunities to attract links from similar trusted sources.
Types of Backlinks
- Dofollow backlinks – Pass authority (“link equity”) to the linked site.
- Nofollow backlinks – Contain a tag telling search engines not to pass ranking value, but still useful for traffic and visibility.
