just have a few questions. 1. do you get all the revenue for yourself if you post adsense ads on blogspot blogs? 2. I tried it and I just got one block way down the page below my post. Can this be customized or is it sort of a take it or leave it from blogger?
You get to keep all the earnings so don't worry about it . Blogspot is customizable and there are many ways you can add Adsense blocks in different places. Check out How to add Adsense code in your blog or website
