Runnerkik, Thanks for the reply.
I agree using my above example about women of this age group going to sites about menopause is ridiculous, and was made to be to support my example only. I am not even targeting this group. I wanted to make a clear cut example, ridiculous our not, so I didn't have to drill down back and forth through multiple questions in the forum.
What I am trying to get across is that we need a way to return sites through some type of demographic search functionality to show which sites certain demographic subsets are using and where they hang out.
As online marketers we are constantly testing to learn more about our customers. Usually we guess and guess until we finally get it right, wasting tons of money and time to refine our customer. I don't like wasting time and money and just want to search for a specific demographic subset and have it return the most popular results/sites people use.
I am not a 50 yr old man, 13 yr old boy a 25 yr old women etc. and it is sometimes extremely difficult to know where you should be targeting new customers and you can't put yourself in someone else shoes that you really no nothing about . What happens is you sometimes make stupid assumptions, based on lack of evidence like the one in my previous example.
I never want make assumptions about my target group and what they are searching for, but it happens all the time. It will continue to happen until some type of search functionality is created for demographic groups.
People think they can find there market through Google Adword, which they can, but I want to go two to three steps ahead, before they even thought of what they might need to type in a certain result, and engage them there.
Great idea about the content network idea for finding your target audience, I just didn't want to have to burn money. Great idea to reverse engineer the process.
