When you type something into google, the most relevant pages will appear. At first, yahoo would have companies pay for the highest spot on the list, but then google changed that. Now, when you type something in, the webpage that has the most links from other sites will appear first, and then the second most linked website will appear next, etc. Companies can still pay for a top spot on the search results, though. A company can pay a certain price, and their website will appear either at the top of the list, or to the right of the list. These pages are easy to spot because they are labled 'sponsored' underneath them.
