When Google visits your site, they are going to take a look at every page they can find. Google will then take a snapshot of each of your pages to store in their system. When a person does a search for a word or phrase, Google returns a list of pages they have found that have that keyword on them.

Pages that have placed their keyword properly will always come up higher than pages that don’t.
