A backlink, also known as an inbound link or incoming link, is a hyperlink on one website that points to another website.

Backlinks are important for search engine optimization (SEO) because they signal to search engines that other websites consider your content valuable enough to link to. Search engines like Google use backlinks as one of the factors to determine the relevance, authority, and popularity of a website or SeoBests.com webpage.

The quality and quantity of backlinks play a significant role in determining a website's ranking in search engine results pages (SERPs). Websites with a higher number of quality backlinks tend to rank higher in search engine results for relevant queries.
