Link building is a fundamental component of search engine optimization (SEO) wherein the objective is to obtain hyperlinks from external websites to one’s own. These backlinks serve as endorsements, signaling to search engines the credibility and authority of a website. The process involves strategically acquiring links through outreach, content creation, and relationship building. Quality is paramount, with an emphasis on links from reputable sources relevant to the content. Organic link building centered around creating valuable content that naturally attracts links, is preferred, while manipulative practices that violate search engine guidelines should be avoided to maintain a positive impact on a site’s SEO.
