Well, a month ago i've contacted a dozen of big celebrity sites, like perezhilton, egotastic, tmz and others in order to buy ads. used gmail email for that no one replied what's going on?)
I would recommend an email address tied to an actual website, plus sites like these generally only work with ad agencies so you might look for the agency that works with them.
used my corporate one with a few, still nothing. the problem is it's adult got only one response from little to medium site while requested like 20 (
Your not going to get an adult site advertised on the types of sites you have listed unfortunately. Is there a reason you have looked at advertising on those sites, is it just because of how big they are? If so why don't you look at other sites (maybe on buyandsellads) and you can probably get your site advertised on a few of those with similar traffic.
I saw the perezhilton one on blogads. You could check that out. The price is very high, think it was listing ad spots at over $1,000, something like that.
i'm not looking to advertise adult sites, but celebrity. it's the corporate email i'm using. probably should change one
Maybe look at BuysSellAds or other networks out there as well... I am sure there are also plenty of publishers in your niche which would be entertainment.
