. I’ve had a few people ask for clarification around the Advertising section, and what all the options there mean. Here’s a summary:
1. Ad networks
These are services like AdSense and Chitika but also smaller or more local ones like NuffNang (which operates out of Australia and Asia). They can probably fit in some of the other categories as well, as they use different models to deliver their ads.
2. Cost Per Impression (CMP)
This is where you sell space for an ad and get paid based upon how many times it loads. Usually you get paid per 1000 impressions of the ad. The rate varies a lot, depending upon topic. There are lots of very low, “remnant” ad networks out there that pay you a pittance per impression, but if you have a higher value niche you can get better money. I’ve been paid up to $40 per 1000 impressions.
3. Cost Per Acquisition (CPA)
These ads pay out only when someone takes some kind of action after clicking the ad. The action might be a sale but could also be them signing up for a service, leaving an email address, etc.
4. Cost Per Click (CPC)
