Backlinks are essential for SEO. Inbound links, in a sense, are a "vote of confidence" between sites. They are one of the most important ranking criteria for search engines. If other sites redirect to your site as a source, the content there is valuable and responsive to your visitors' needs. The total number of backlinks, especially high-quality backlinks, will help you beat your competitors in search engine rankings and significantly raise your domain authority. The use of links in a search engine algorithm is nothing new. Backlinks were the foundation of Google's original algorithm (called "PageRank"). Although Google has made thousands of changes to its algorithm, backlinks remain key ranking factors.
