Google is a business. thousands of advertisers use Google AdWords program to promote their products and services. SdWords in probably the largest program of its kind. the revenue the company generates is derived from offering its search technology to companies and from the sale of advertising displayes on Google and on other sites across the web.
however, you may have never seen an ad on google. that's because google does not allow ads to be displayes on the results pages unless they're relevant to the esults page on wich they're shown. google firmly believes that ads can provide useful information if, and only if, they are relevant to what you wish to find.
google has also proven that advertising can be effective without being flashy. google does not accept pop-up advertising, which interferes with your ability to see the content you've requestes. they've found that text ads (AdWords) attract much more interest than ads appearing randomly.
advertising on google is alwais clearly identified as a "sponsored link". it is a core value for google not to mix advertising and search results: they are clearly distinguished. internet users trust google's objectivity and no short-term gain could ever justify breaching that trust
