The CPM pricing model may be the most popular, but CPC offers a unique advantage to bloggers who cultivate an audience that’s highly engaged. CPC stands for “cost per click”, meaning that each time an ad is clicked, you earn extra income. Clicks typically tell advertisers how effective their advertisements are. This kind of pricing model is popular with ad networks like Google Adsense. As the publisher of a blog, advertising can provide a healthy revenue stream for your online content. Advertisers are willing to pay to gain exposure to your audience. In the same way that a newspaper with a large circulation can charge advertisers more, the more popular your site and content become the more you can earn.
