I am somewhat confuse the difference between the two. Can you use both of them at the same time? How are they different? Thanks.
Google Ad manager is aimed for large publishing houses who have large ad inventory. Generally these publishers integrate adsense with admanager or fill up their unsold ad inventory using adsense. I am using ad manager for some sites of mine.
does ad manager Allow people to bid for your ad space automaticaly, or do you have to go out and find advertisers? I'm realy confused about it all to be honest, is there a chance for me to make more money here for my site or not?
