Definition: Ads you place for your web site with a search engine, such as Google or Yahoo. You bid the amount you are willing to pay per click. The more you bid, the higher your ad will appear in the search engine results. Google has implemented an additional factor in where you ads rank that is based on the relevancy or importance that Google places on your site, which is very difficult to manipulate.

Also Known As: PPC Advertising, Google AdWords

Examples: Using a pay per click advertising tool, like Google AdWords, your ads can appear for keywords you select whenever someone conducts a search using your keyword phrase. PPC can lead to increased traffic for your website.
