What is a backlink?

A backlink is a hyperlink on one website that points to a page on a different website. Backlinks are one of the most important ranking factors in search engine algorithms because they act as votes of confidence from other sites. The more high-quality backlinks a domain has, the more authority search engines assign to it.

Are the backlinks to sigma.org dofollow or nofollow?
