1. What is a Backlink?

A backlink is a link from one website to another website.

Example:

• Website A links to Website B
  👉 Website B receives a backlink

In simple terms:

A backlink is a “vote of confidence” from one website to another.

When many websites link to your page, Google assumes your content is valuable and trustworthy.

2. Why Backlinks Are Important for SEO

Backlinks are important because they help search engines:

2.1 Measure Authority

Websites with more quality backlinks are seen as more authoritative.

2.2 Improve Rankings

Backlinks are one of Google’s top ranking signals.

3. Types of Backlinks

Not all backlinks are the same. Some help SEO, others can hurt it.

3.1 Dofollow Backlinks

Google uses backlinks as a trust system.
