HI I build a new website and i don't know for what banner size i should optimize my website. The question i have is what banner size 728x90 or 300x250 has the most CPC competition in AdWords hop someone that is using AdWords can help me answer this question. If i have to type blindly i would say the 728x90 banner because it is 268 pixels more then the 300x250 banner.
Hello Friend, Firstly show your website, the second thing is Adword competition is according to the keyword and according to the banner. If keywords are more competitive then you pay More, same in the banner your cpc cost depends upon the banner size. Thanks
