Please review Adsense placement

Hi. New to Digital Point. Looking for some feedback.

Was making about $200 per month. Original set up had 300x250 at bottom of posts, 160x600 in right column.

Changed Adsense layout mid Jan. Made $350+.

Changed again at beginning of Feb. Made $700+.

Changed again at end of Feb. On target to make $1,110+ in March. Currently showing 3 blocks on home page: 728x90 text/image below header, 180x90 link unit in first post teaser, 300x250 text/image in second post teaser. on posts: 728x90 text/image below header, 180x90 link unit at top of post and 300x250 text/image in middle of post.

Also showing other ads from other services and affiliate programs.

Steady and slow traffic increase over the last 3 years so I don't attribute the income increase to traffic increase.

I'd like to some feedback on how to further optimize. If you need any other info, please let me know.

Thanks for your feedback. I'm looking to optimize further. Do you know of any articles about how to do testing? How about YieldBuild?
