I've been using Adsense for a while but I haven't seen significant earnings yet. I usually see a few cents here and there which isn't great but I'm still happy since I enjoy blogging about teaching English in Korea. Check out my blog and Adsense placement here and tell me what you think. The Daily Kimchi - http://thedailykimchi.blogspot.com/ What do you guys do with Adsense for your Blogger blog? I suppose a new template would give me more options but I'm a newbie when it comes to CSS and HTML. Thanks guys and gals!
There is a setting in adsense that makes sure that empty adblocks disappear. Since you have too many adblocks on a page, that option would help make that fact invisible for users. Other than that I think you just need more readers.
