Backlinks

Backlinks are links from other websites that point at yours. Search engines read each one as a recommendation: when a site links to a page, it signals that someone else found the content worth referring to. Links have carried SEO since Google built its search engine on PageRank, which ranked pages by the links aimed at them.

Quality beats volume

One link from a recognized industry publication moves more than fifty from random directories. Google weighs the authority of the linking site and the topical fit between the two pages: a link from an accounting site to an accounting page counts for more than one with no shared context. That is also why bought links and link networks are a poor trade. At worst they trigger a penalty, and the cleanup afterwards costs more than the links ever returned.

Good backlinks appear when other people have a reason to refer: original data, thorough guides, useful tools, strong cases. Digital PR is the journalistic branch of that work, where stories and numbers give editors a concrete occasion to cite a website.

AI assistants lean on the same authority signals. Sites with a strong backlink profile and steady brand mentions turn up more often as cited sources in AI answers. The guide to link building takes the work from prospect list to placed link.
