If Website A links to Website B, that’s a backlink for Website B.

If a blog mentions your site and includes a clickable link, that’s also a backlink.
Backlinks are like votes of confidence from other websites. The more high-quality backlinks your site has, the more search engines like Google trust it—helping you rank higher.
