In-Depth Definition
Link building is the active process of getting other websites to link to your pages. It remains one of the most impactful SEO strategies because backlinks are a primary ranking signal for Google and contribute to the domain authority that influences AI citation decisions.
Modern link building focuses on quality over quantity. Ethical, sustainable approaches include digital PR campaigns, creating link-worthy content assets (research, tools, guides), resource page outreach, broken link reclamation, expert roundup participation, and strategic guest contributions.
Key metrics for evaluating link quality include the linking domain's authority score, topical relevance to your industry, editorial context of the link placement, whether the link is dofollow, and the quality of traffic the linking site receives.
