336x280, 300x250 or 250x250? It just came to me because I was always using 336x280, but lately I noticed that maybe 300x250, which are almost as big, have more frequently banners. Is it true? Which one do you tend to choose among these 3?
i prefer 726*90 banner and its not mentioned! also single Ad unit embeded in thread index on VBforum!
On my research, Big Ad Units will gives higher CTR but only generate low earnings per click. At the opposite, Small Ad Units give you more earnings per click but you'll get less CTR. It's because of AdSense Smartpricing. An Ad block with many links inside will give less earnings per click. I've already discuss about it at : www.angellica2017.com/maximize-adsense-ctr-and-adsense-earnings-per-click
Interesting! I never thought of that. I didn't mention other formats because I wanted to make some kind of comparison between big boxed or rectangular formats. But now the question might be "big boxed, small boxed or banner"?
Good news... That's what usually called CPM ads. That was based on impressions. CPM ads fill entire block with the links.
