Adwords provides advertisers with a way to advertise on google's search engine results pages. Instead of charging advertisers an amount based on how many times their ads show, they only charge the advertiser when a surfer actually clicks their ads. That's why it's called pay per click.
Google's CPC (Cost Per Click) based text advertising. AdWords takes clickthrough rate into consideration in addition to advertiser?s bid to determine the ad?s relative position within the paid search results. Google applies such a weighting factor in order to feature those paid search results that more popular and thus presumably more relevant and useful. Google has also started taking into account the quality of the landing page and applying a quality score to the landing pages.
