I am an Adsense Publisher not proud but satisfied in some way. I always experiment with Adsense units. Now I am going to share a tip that probably you may not have heard. I have tried many Adsense alternatives but unfortunately no one is one tenth of Adsense. So there is no way to ignore Google Adsense unless Adsense ignores you.
I have tried this many times. Finally I can make a decision. I have a blog (here). I have some other blogs too. I have worked hard on my blog and now getting little traffic and money, thanks to Google Adsense. When I place Adsense ads on more than one blog my revenue always goes down. Suppose my one blog is earning me daily $10, but after placing ads on my other blogs I will get only $4 or $5.
What could be the reason I do not know because Goggle never discussed about it. I think it will be the matter of reputation, one blog has a good reputation and other has no reputation.
So if you have more than one blog and running Adsense on all blogs, keep Adsense only on one blog that you think is the best. On other blogs try other ad networks. If you other blogs also have good reputation you can try Adsense again on them.
