Duplicate Ads on same page avalon37 msg:4531236 11:29 pm on Dec 26, 2012 (gmt 0) I serve 3 Adsense ads on most pages on my site; same size ads and format. It's actually the same code in 3 places. I frequently see the same ad/advertiser displayed by Google. Does anyone experience this?

I only see it if I have two blocks of adverts on a page... BUT, they belong to separate accounts. It may be different if they were the same account. I don't know. I never use more than two, and mostly use just one per page. HuskyPup msg:4531246 12:17 am on Dec 27, 2012 (gmt 0)
Yep, on my own pages even with three different ad sizes only occasionally however on Statcounter I see it all the time with their leaderboard and skyscraper. netmeg msg:4531549 8:46 pm on Dec 27, 2012 (gmt 0)
I see them occasionally, in different circumstances. I always figured it was because there wasn't enough ad inventory for the page, because the problem seemed to go away when I went from 3 ad units to two. But lately I've been seeing them a LOT with remarketing (where the ads from a site you've visited follow you around the net) where they put the remarketing ads on every AdSense spot on the page. Again, bad advertisers and a bad delivery system. piatkow msg:4531715 2:02 pm on Dec 28, 2012 (gmt 0)
I have seen it but only once or twice. eeek msg:4531791 12:53 am on Dec 29, 2012 (gmt 0)
I always figured it was because there wasn't enough ad inventory for the page I'm sure that's the excuse Google would give you. But I don't think that's actually the case. More likely they just aren't able to control the ads well enough to prevent it.
