Keywords are what we put into Google (other search engines are available) to find what we are looking for. For example, if you type “Taco Bell in Bacup” you will get a list of relevant search results.
You won’t find one in Bacup by

Keywords are also important for businesses too. If inspired by the last paragraph, you have now decided to open a branch of Taco Bell in Bacup, you would want to make sure you appear on or near the top of the search results.
