Hello I've got two questions regarding Adsense ad 1. I am using one ad size 468 x 60 with same channel in over 500 pages. Will Adsense automatically target keywords in each pages, which have different content? 2. if I have variety of content, will this increase my CPC or eCPM?
1. 468 x 60 is a bad adsense format, try 300 x 250 or 336 x 280. Yes, Each adsense advertisement is different depend of your content. 2. CPC and ECPM is varied based on your niche and ad placement
I agree - but 336 x 280 large rectangle has been proven to be the best of the lot - that's the one the pro's use after doing extensive testing
also the 336 x 280 format placed within the content get me a higher CTR (between 8-12%, depending on niche) and bigger targeted ads.
