what is the best size that help you earn the most with Adsense?

I read the 8 resolutions for 2008 of Adsense blog and the previous one about placement targeting suggestions that 300x250 is the best one as it has increased some additional money for me, i decided to use this only for my blog at: vietblogviet.com. What do you think? has this size help you earn more? share your ideas here

 

It depend on self design.
Just like DP not suit for rectangle ads however it's suit for banner

 

The best performing ad is the big rectangle, official Google information from Google Adsense Blog!

 

I think that the size of adsense is not too important. But it is important how to blind your adsense.

 

It's all about placement, if you just put a certain size ad on your site because you read it works well. That's never going to work. You have to BLEND! all sizes can be work well if you know how to blend

 

The large text block in the middle of teh page is the absolute best.

 

The large rectangle.. It worked best for me..

 

Yea, large rectangle works best for me too. Its the most apparant, just blend it away right.

 

thanks, that is why i only use 300x250 size for my blog now

 

yes, i think this is the best format too.
you can read this article if you want to find more, it's about the best performing ads

 

For me, both 300x250 and 250*250 are the best

 

well, it depend, so just try thrm out

 

tyr different sizes nd different color combination too for knowing what works best for you

 

I just saw an strange appearance of GA, it must be optimized by a third party program but legal, do you think so, it is called PubMatic, has anyone tried this before?

 

I think 336*280 gives us the maximum hits

 

there is no best performing uniform ad that work for all sites across the board. it all depends on your site layout, niche, traffic, how well the ads are blended in, etc. for example, link units usually don;t get good CTR but i have see some sites getting good CTR from link units
