Link building is a search engine optimization (SEO) strategy aimed at improving a website’s visibility and ranking by increasing the number of high-quality external links (backlinks) pointing to it. This approach also includes optimizing the site’s internal linking structure to strengthen the authority of strategic pages. Link building can be achieved organically through high-quality content or actively developed through link acquisition, exchanges, or the creation of engaging content. A quality-driven approach is preferred to comply with search engine criteria and avoid penalties associated with abusive practices.
