What is Keyword Research?

Keywords are words and phrases typed into search engines to find what one is looking for.

For instance, if you were looking to buy a car, you might type “used cars for sale” into the Google search engine. This is known as a keyword or key phrase.

Keyword research is finding search terms or phrases that people enter into search engines relevant to your topic of interest.
