What is the main purpose of using keyword in SEO?

Hi friends,
Yes, keywords are important.

However it is very important to know that a "a genuine use of keywords" is a positive factor rather than just a mere stuffing-up of keywords.

Today, Search engines are much better at analyzing web pages than before. These search engines can detect a genuine use of keywords v/s stuffing up. That is done by calculating the keyword density of the web page content.

As the future arrives, search engines will only get more human. You need to start treating search engines as : humans with a good sense of judgement.

Keywords are the search terms used to find your website in search engines. They are selected using Google keyword planner to rank websites higher in search results. They are implemented on the website meta tags and content to help increase the visibility of your domain in search engines.

The main purpose of inserting targeted keywords is to make your website visible on the search engine. It helps to visible your website if the users inserted related to your keywords term.
