The Google Slap is a term used unaffectionately by mainly small businesses that rely on
AdWords accounts through Google to drum up business for their sites. AdWords for Google allows people to have their advertisements for their own businesses on pages with keywords or subjects that relate to their products. Normally people who hold AdWords accounts pay per each time someone clicks on their ad, usually at about $.05-.10 US Dollars (USD) per click.
However, if Google finds or determines that the page that potential customers visit when they click on the ad is not related, is poor in quality, or even loads too slowly, they may take punitive action in the form of a Google Slap. Basically, the Google Slap accomplishes several things at once. First, it drives up the price of your pay per click amount, sometimes asking as much as $10USD per click, which most small vendors cannot afford to pay. Second, they may reduce your page ranking (PR), which will automatically mean you have to pay more to have your ads featured through AdWords.
