What is a backlink?

A backlink is a hyperlink that points from one website to another. When website A links to website B, that link counts as a backlink for website B. Search engines like Google interpret backlinks as votes of confidence. If multiple reputable sites link to your content, search engines infer that your site offers value worth recommending, which improves your chances of ranking higher in search results for related terms.

Not all backlinks carry equal weight. A link from an established news site carries more authority than a link from a brand-new blog. Search engines evaluate the source's own credibility, relevance to your industry, and linking patterns when assessing backlink quality.

Two HTML attributes control how search engines treat backlinks. A dofollow link (the default) passes authority from the linking site to the target site and influences rankings. A nofollow link includes the rel="nofollow" attribute, which tells search engines not to count it as a trust signal. Publishers use nofollow for paid sponsorships, user-generated content, or links they cannot personally verify.

For Malaysian businesses competing in search results, earning dofollow backlinks from relevant local and industry sources strengthens your domain authority. Agencies working on content link building focus on acquiring these quality backlinks as part of a broader SEO strategy.
