Link building remains one of the most consequential—and misunderstood—parts of SEO. A backlink is a third-party vote of confidence in your content, and Google still weights these signals heavily in rankings. But the mechanics have shifted. Links aren't just about ranking on Google anymore; they're signals that feed into LLMs, influence brand perception, and determine whether your content gets cited in AI-powered answers. The quality of who links to you matters far more than the quantity, and cheap links carry real costs—both algorithmically and in opportunity cost.
The field is consolidating around a few hard truths. First, links follow genuine topical authority and brand strength; you can't shortcut your way there with prospecting alone. Second, PR and SEO have merged operationally—the same third-party signals that generate backlinks now build the brand mentions and earned media that power AI visibility. Third, link building works best when tied to sustainable business models and content that people actually want to reference, not just rank. The days of treating links as a separate tactic are over. Practitioners are increasingly thinking about earned coverage holistically: what newsworthy moves or content genuinely deserve to be written about by others, and how do you create the conditions for that to happen repeatedly.
Focus on building things worth linking to and being the kind of brand people mention unprompted.
