Keywords are important terms that people search for on Google or other search engines. For example, if you search for “electric cars,” that's a keyword. Most people today are no longer just looking for individual words, but for combinations of several words.
For example, “Tesla electric cars” or “Tesla Model 3 range.” These are called keyword combinations. They describe what someone is looking for in more detail.
Here is an example: You are interested in Tesla electric cars and want to know more about the range. So you type in Google: “Tesla Model 3 range”
The search results will now show you websites that provide information about the Tesla Model 3 range. You click on one of these pages and find the information you were looking for. This is how the right keyword combinations lead people to websites that deliver exactly what they're looking for. Keywords are an important tool for a website so that content can be found on the Internet.
