I'm running a site which has users from all over the world (although the site is English language). When a user logs in I can tell from the DB which country they are in and serve appropriate ads.
However, I require some ads which would be appropriate for when I do not know the country (i.e. before login) and for those countrys which do not have enough users to be worth running a dedicated campaign.
So, do you know of any banner / button ads (preferably from CJ or Tradedoubler) which would be suitable to serve to people all over the globe? (But not AdSense as I already use that).
PS - It does not matter what the adverts are for as the site is not targetted at a particular audience. The only no-nos are casinos and adult sites.
