Google AdWords is a pay-per-click advertising program. When you perform a search on Google, the results will be in the main body of the page, and over on the right-hand side will be a column of small adverts, each with a link to a web page.
These are AdWords ads, and if you click on a link in any of the small ads, the person who is running that particular ad will have to pay Google a certain amount. This is what is meant by pay-per-click.
