Thank you again for those helpful responses.
I wanted to answer some of the questions asked.
Some specifics about the audience being delivered: M18-34, college-educated, from USA. They sometimes ask me to recommend products that I think are good. Enthusiastic about subject.
In terms of why are the websites a good place to advertise, in addition to the above, there are not a lot of ads on a page so I think visitors will remember an ad if they see it.
I think advertising on the sites would help the advertiser with online sales and people buying more of their products from local stores selling their products.
Do you think these characteristics would be something that would interest advertisers and agencies?
With regard to tracking, I think you mean more than traffic. Can you please tell me what ad agencies want to have tracked?
