which ads can improve my CTR

which ads can improve CTR and my earnings. i heard use wide skyscraper and 336*280 rectangler . at the top of the page but what kind of link unit i should use. banner type or skyscraper and what is the size of link unit?

 

This all depends on your layout... do you have a link to your site that you want to use adsense on?

Also: from my experience the 368 x 250 ad works better than the wide skyscraper format.

 

and what about link unit

 

No problem with link units, however they have LOWer ctrs... blend them well into your site so they somewhat ressemble a navigation bar (but don't go against TOS..) and it works out better.

 

but i want to know which size in link unit i should use

 

ususally most of the pl prefer 468xx not 768 one.... I also personally use 468x78

 

I suggest 368x250. even many times google mailed me suggesting to use it for my websites.

 

guest we r talking about link unit . about ad unit ur suggestion is right
