Absolute n00b to adsense - no shame in admitting it... I have a blogspot blog with adsense recently installed - what is the best way of getting click throughs in terms of visitors, layout, background colour, size of ads etc. If you have any advice from more experienced adsense guys it is much appreciated.
I wrote a post about the best adsense colors, but really it depends on your website. Going for 000080 link color is really a good try. Make sure you make the borders go (border color = your sites color). Also use large rectangles, they offer the best CTR.
These was a mention about the best adsense size using the larger ad units. You can read about it here. Hope that helps.
