In search engine optimization, link building is an important action in the context of off-page optimization. Search engines rate websites particularly well if they are linked to frequently. These are also called backlinks. This is not just about the quantity here, however, but increasingly mainly about the quality of the links. The significance the website has (from the search engine's perspective) that is linking to your own website therefore also plays an important role. Among other things, high quality content is important in order to get a great number of backlinks. Backlinks are not only of interest for link building, but also for bringing more visitors to the website.
