1. Sign up for a pay-per-hit or 'CPM' ad network. (CPM refers to 'cost per mille,' or the rate you'll receive per 1,000 ad views.) Items to consider include the rate paid per 1,000 views and the minimum income necessary to earn before you'll be paid. Consult the ProBlogger link in the Resources section below for a list of 12 CPM providers that will serve up advertising on your site just like Google Adsense.
2. Decide where you'd like to add CPM advertising on your website. If you already have successful banner ads, affiliate links or pay-per-click ads on your site, you may not to displace them for (generally) lower-paying CPM ads. However, CPM ads can be an easy addition to an established website or a simply way to start advertising on your website from the very first day.
3. Add the CPM provider's html code to your website in the appropriate places in your code. Your ad provider will provide the necessary coding to automatically pull ads from their database onto your site--simply follow their installation instructions to display your new ads in the intended places on your site.
4. Log into your CPM network account periodically to track how your advertising is performing. Of course, the more visitors you have, the more your ads will be viewed, and the greater pay-per-hit income you'll make.
