I've basically done what you want to do and decided to use Artiseer to make all my themes (assuming your using wordpress), it makes fantastic looking sites at just a few clicks of a button.

I have a steady CTR of around 10% which isn't great but I'm happy with it as it's not like I'm throwing the adsense ads in their face, I'm trying to provide a good looking site with great content and relevant ads. I hear people who use Xfactors template often get in excess of 20%CTR.

Should I put minimal content on to force users to click on adsense for more info or give more content to make site better quality?

I'd say there are far more experienced people here that could answer that....I put my site up with 3 posts intially, all good quality informative articles that are around 400 words in each article, a few pictures to go with the articles and a large adsense rectangle at the top of my page with another adsense vertical in the sidebar.

I don't even put adsense in every post as I don't want my sites to look like they are exclusively made for adsense. They generally rank within the first couple of pages pretty quickly then I just add links and add content as I want to build these sites from micro niche sites to decent size niche sites that do provide relevant information and will continue to make money down the line.

So I guess to answer your question, No I don't 'force' them to click on my ads but as I mentioned my CTR isn't anything to brag about.....

i am using my own template designed with DW CS3, nothing fancy, my concept is the simpler the better...
