"YPN allows only one ad unit per page " Just to let you people know. I sent query to YPN and got clear response. (I posted this in different thread, but that topic is not obvious for this info)
Good on them if that's true indeed. Quality over quantity. Well, I guess they don't have enough ads to fill up more than one anyway but at least it will prevent it being abused by spam sites to an extent.
I don't think they have the impression system set up right yet, it showed up as triple the amount of actual impression when I had three ad units up.
in your YPN account next to the word click is a ? and there it says you can have more then 1 ad per page Not just that, I just called 3 times in a row and told them that in reports it says you can have more then one ad per page so I asked can you or can you not have more then 1 ad per page and all3 times they said you can have even 3 ads per page, so you guys need to stop giving out flase info. call up and ask like I did and read your account. The final answer is yes you can have more then 1 ad per page.
this is written response from yahoo customer support I am not sure why yahoo peole are giving up different info
This is word for word in the ypn account. "An ad unit impression is recorded each time an ad unit is displayed on a page. A page may contain one or more ad units, For instance. each time a user views a page that contains 2 ad units then 2 ad unit impressions are recorded." Second of all call this number(866) 785-2636. and tell them you are part of the ypn network and in your account it says this and ask if you can have more then one ad unitand there answer from 3 seperate people was that yopu can indeed have more then 1 adunit. Enough said
Seems like we got more or less official word that we can have multiple ad units per page, see this post: http://forums.digitalpoint.com/showpost.php?p=325829&postcount=8
