I've been trying to get through to Doubleclick over the past few days but to no avail. I guess they are very busy as they do not return phone calls, contact requests etc. Anyway, I'd love to get some info or feedback on this product. It seems DART for Publishers is an ad manager so that I can manage campaigns on my site, revenue etc. Has anyone used it before? What's the approximate cost? I'm launching a major web portal and just want to make sure I understand how this works correctly. How do I go about getting larger advertisers to advertise on my website? DART has an advertisers exchange which would seem to be the place to get advertisers on my site. I understand it all has to do with your reputation, page views etc. but just looking for advice as to how this all works. Which networks should I pursue? Thanks
