Re-optimizing some of my older sites

In an effort to meet my earning goals for this month I'm following my own advice and going through my older Adsense sites and re-optimizing them. None of these sites are big earners, but they earn enough money to be worthwhile. On the first site I have already seen the revenue double, which should put an extra couple of hundred dollars to my bottom line at the end of the month. Not bad for less than an hour of work.

The optimizations I've been doing include updating the CSS stylesheet and new ad placements. I have a few more sites to do, so I'm pretty excited to see the end results.

Ctr?

I need to do this too. I've done it on a few sites as I move them from one server to another but there are a few still without optimized adsense placements.

Well, I'm not sure what I can reveal because of the Google TOS, but its closer to 20% than 10%

I also need to do some optimization for my sites so that I can improve ad placement.

Its not simply placement but colors & the typeface of the rest of the site
