Link building plays an important role in SEO promotion, as search engines use external links as one of the main criteria for determining its authority and relevance to a search query. The more resources link to your site, the higher the chance that the search engine will consider it a high-quality and authoritative resource.
Links from authoritative and relevant resources increase the authority of your site in the eyes of search engines. They indicate that your content is useful and interesting for users, and you can be trusted. On the contrary, links from low-quality and irrelevant donors can worsen your reputation and negatively affect positions and traffic.
