Let's say the same CPM ad (1 advertiser) is displaying in a banner and leaderboard format. Does the leaderboard pay more, or the same, ie does/can the advertiser specify their bid depending on the format? The text is much larger in the leaderboard format so I would imagine they pay more? Thanks for any insight on this.
it all depends on where you put these ad formats really. But checking the results I had: - just below the menu, i'd go for a leaderboard - in a forum i'd go either for a banner or a 250*250 just below the first post in a thread. - in single text entries I'd go for a 250*250 above the text field. - etc et cetc etc.
