AdWords

AdWords is Googles version of the pay-per-click advertising model. It allows you to display ads which link directly to your website when searches are done for your chosen keywords or keyphrases. These ads are located to the right of the results which Google gives you for a search and they're also displayed on Googles many partner sites

Just as the popularity of Googles search engine is derived from its strong technologically advanced features and results so too is its advertising program AdWords.
