What is a Backlink in Search Engine Optimization

What is a Backlink in SEO?

A backlink is simply a link that points from one site to another. When a website links to your site, it's called a backlink for your site. Backlinks are essential for SEO because they act as votes of confidence from one site to another site.

1. Do-follow backlinks

Do-follow backlinks are the most valuable type of backlink because they're counted as a vote by Google. When someone links to your site with a do-follow link, they're telling Google that your site is worth linking to.

Not all backlinks should be tagged as ‘do-follow' because it's unnatural to have all backlinks as do-follow.
