Last week, Google announced the beta test of their new pay-per-action (PPA) advertising program. In addition, Google mentioned a new ad format, the text link ad (which will presumably be similar to the current referral text link unit.), would be available. This new ad format, along with the new PPA (or affiliate) model, will open up new potentials for bloggers to make money from their blogs.
There is a big difference between Google’s new CPA ads and their traditional, context-based AdSense ads. According to the AdSense program’s policy, publisher is not allowed to call attention or encourage their site’s readers to click on the ads, since the advertiser pays on a per-click basis. If a blogger writes, “It’s been a tough month, please be kind enough to click on a few Google ads to help make ends meet,” there’s a very good chance said blogger will find their AdSense account suspended. But with the new CPA ads, since the advertiser only pays when a specific action is taken by the user, a publisher is allowed to encourage or draw attention to the ads.
Google’s existing ad units are meant to act as supplements to the content of a site; for a blog, you can place an AdSense unit above, below, to the side, or even in the middle of a blog post, but the unit physically looks separate from the content.
