Backlinks are one of the most essential ranking factors in search engine optimization (SEO). If you are trying to improve your website’s authority, organic traffic, or visibility in Google — you must understand backlinks thoroughly.

What is a Backlink?
A backlink (also called an inbound link or incoming link) is a hyperlink from one website that points to another. When a website links to your site, that’s considered a backlink. Backlinks help search engines understand how trustworthy and popular your content is.
Example: If a popular blog like Moz links to your website, it tells Google that your content is valuable and trustworthy.
