Why Backlink is Important for SEO?

What exactly is a backlink?

When one website links to another, a backlink is created. Backlinks can also be referred to as “inbound links” or “incoming links.” Backlinks are essential for SEO.
What is the importance of backlinks?
Backlinks are especially helpful for SEO because they represent a “vote of confidence” from one site to another.

Backlinks to your website, in essence, are a signal to search engines that others approve of your content. When multiple sites link to the same webpage or website, search engines can infer that the content is worth linking to and, thus, worth appearing on a SERP. As a result, obtaining these backlinks can improve a site’s ranking position or search visibility.

Obtaining and disseminating backlinks
Backlinks are an essential element of off-site SEO. Link building or link building is the process of gaining these links.

Some backlinks are more powerful than others by definition. Backlinks from trusted, popular, high-authority sites are the most valuable to get, while backlinks from low-authority, potentially spammy sites are normally on the opposite end of the spectrum. While whether or not a link is following (i.e. whether or not a site owner actively advises search engines to pass, or not pass, link equity) is important, don’t overlook the usefulness of NO-Follow links. Getting listed on high-quality websites can increase your visibility gain traction.
