What Are Keywords in SEO?

Keywords are the foundation of Search Engine Optimization (SEO). They are the words and phrases that people type into search engines like Google when they are looking for information, products, or services.

If your website content contains the right keywords, search engines can easily understand your page and show it to the correct audience.

Definition of Keywords in SEO

In simple words:

Keywords are the search terms that users enter into search engines to find content online.

For example:

  • “Best SEO tools”

  • “How to rank website on Google”

  • “What is keyword research”

These are all keywords.

Why Are Keywords Important in SEO?

Keywords help both search engines and users understand what your content is about.

Here’s why keywords are important:

  • They improve website visibility

  • They bring targeted traffic to your website

  • They help your content rank higher in Google

  • They help match user search intent

Without keywords, search engines would not know how to categorize or rank your web pages.
