Search engine advertising is one of the most popular forms of PPV. It allows advertisers to bid for ad placement in a search engine's sponsored links when someone searches on a keyword that is related to their business offering. For example, if we bid on the keyword “PPV software,” our ad might show up in the very top spot on the Google results page
Every time our ad is clicked, sending a visitor to our website, we have to pay the search engine a small fee. When PPV is working correctly, the fee is trivial, because the visit is worth more than what you pay for it. In other words, if we pay $3 for a click, but the click results in a $300 sale, then we’ve made a hefty profit.
