When a website is popular and has a lot of traffic, then it’s easy to get good ad revenue. But if you are a small fish in a big pond, then it’s not so great. There is a good chance you could get booted from Google’s AdSense program because some idiot sitting on the other side of the globe is illogically clicking the links or whatever the reason may be, or worse yet, you may not even be selected into the program.
Ofcourse, there are alternatives such as AdBrite. However, don’t stick with just a single Ad Network. Based on popularity of AdBrite, I tried doing this and my CTR is very low and further, AdBrite seem to be serving ads with very low rates (CPM or CPC) for low volume sites. It’s understandable that they want to maximize their advertisers value of advertising through their network. However, low volume doesn’t mean quality leads.
The main problem with all the context-less advertising networks is, they heavily rely on category of the website (how targeted can you get with just a handful of categories?) and geo location of the visitor. So, with current techniques used by these networks, there is no easy way for them to measure the worthiness of a site or the right way to match the advertisers to the publishers besides based on metrics such as alexa ranking.
So, the best approach is to go with multiple ad networks. Some of the ones I have tried are AdEngage and Bidvertiser. I noticed a different CTR with each network. This could be based on how and where I placed the ads from these different networks, but there also might certainly be some factor related to what ads are getting served on your site through these non-context ad networks. With just a few days of experimenting, I am quite pleased at present with Bidvertiser. I am still running AdBrite but may gradually get rid of it if I don’t get good CTRs or if they keep showing only “Advertise On This Site” and not really putting ads (what a waste of space, and I guess this has to do with supply and demand. They perhaps have more ad real estate from publishers than the advertisers). The key is to go with networks that have a more balanced supply and demand so that it’s possible to get higher CPC/CPM ads as well and not the bottom most of the pile.
