These are sites that help you make money with your web site or blog by using some of the space on your site to advertise for other sites or products. In many ad programs, you earn whenever someone visits your site and clicks on the ad (referred to as pay-per-click or PPC ads). In others, you earn whenever an ad is viewed - these ads are pay-per-impression.
There are a number of different types of ads: banner ads, text ads, ads inserted into pictures or videos, interstitial ads which appear when people are moving from one page to another on your site, pop-up/pop-under ads, and so on. Ads may also be contextual, which mean that the ad is based on the content of the page that the ad appears on.
Webmasters should always remember that some forms of advertising are less popular than others. The best ads blend in with your site, do not annoy or harass your visitors, and are relevant enough so that your visitors will occasionally click on them.
