If you’ve ever wondered “what is a backlink?”, you’re not alone. If you’re new to SEO, you’ve probably come across the term “backlink” quite a few times. It shows up often for a reason.
Backlinks are not just simple links. They are the backbone of how the internet works, creating a web of connections that guide both users and search engines.
Understanding backlinks is essential for anyone looking to improve their website’s visibility online.
What Is a Backlink Exactly?
About understanding what is a backlink and how it works, a backlink, also known as an inbound link or incoming link, is a hyperlink that points from one website to another.
You can think of it as a vote of confidence. When another site links to your content, it signals to search engines that your content is useful and trustworthy.
Example:
Let’s say Ahrefs, a leading SEO tool, links to your blog post about keyword research. That backlink tells Google that your content is worth referencing.

Why Are Backlinks Important for SEO?
Backlinks are one of the most critical ranking factors in Google’s algorithm. Here’s why:
âś… Authority Boost
If a trusted and high-quality website links to yours, it passes some of that credibility to your site.
Example: A backlink from a well-known news site like TechCrunch increases your domain authority.
âś… More Visibility
Backlinks bring new visitors by helping people discover your site from other sources.
Each backlink acts like a road sign that leads users to your website.
âś… Faster Indexing
Search engine bots use links to find and index new pages more quickly.
Example: If your blog is referenced by an already indexed site, your post might be crawled within minutes.
âś… Trust and Credibility
When respected sites link to you, it builds user trust. People are more likely to read, share, or buy from a site that’s endorsed by others.
According to Moz, backlinks are critical for domain authority.
