PPC stands for Pay-Per-Click - a popular advertising technique on the Internet. Found
on websites, advertising networks, and especially on search engines, PPC advertising
involves sponsored links that are typically in the form of text ads. These are usually
placed close to search results, where an advertiser pays a particular amount to visitors
who click on these links or banners and land on the advertiser's web page.
In essence, PPC advertising is all about bidding for the top or leading position on search
engine results and listings. Advertisers do this by buying or bidding on keyword phrases
that are relevant to their products or services - the higher the bid, the higher the spot on
the search results, the more the people will find the ad (and click on it) to go to their
websites (this is why some people call it "keyword auctioning"). Advertisers would then
pay the bidding price every time a visitor clicks through the website.
