Can a publisher prevent CPM bids on their site ?

Hello,

 

I am trying to bid by "viewable CPM" on a set of 5 valuable sites. I have gradually increased the bid from 0.3 $ CPM to 1.5 $ CPM in 3 days ( this is for Romania , where bids are usually cheaper), but I am not getting any impressions.

 

The targeting method is managed placements without any other restrictions. I have many banner sizes and text ads. There shouldn't be any reason to prevent serving besides bids in my opinion, yet still I am not getting impressions.

 

The advertised site is not blocked by those sites because CPC bids do generate impressions and clicks .

 

Now I am wondering , can that publisher simply have blocked CPM bidding for their adsense account , or what is going on ?

 

The sites have high traffic and their audience is valuable, since they are focused on business news ,stories and tutorials.

There is limited to a bid, for winning  an impression. (Especially on display)

On the display network, since there are so many sites  (placements) which could be relevant I  do not recommend to win impressions / slots by all means...

Adsense blocks advertisers based on the URL not based on bidding method.
The issue here is when the system converts CPM to CPC, to compare "apple- to apple", or vice versa (depending on the auction), your bid comes to low, OR your QS is low and thus the banner doesn't win a slot.

Ok, thanks.

 

So you would suggest to keep increasing the bid until I find the triggering value for CPM ?

Ok, thank you for the advice. It is just that in this case the client wants to appear on those sites, I hope a higher bid will start serving impressions . These placements are named very attractive for businesses such as www.manager.ro  or www.capital.ro
