Hi, i am interested in starting up a fantasy soccer website. I believe i have found a niche market where i expect to have between 3000-5000 members.
I plan to give a free service and generate revenue through selling advertising space and sponsorship.
How do i go about valuing the advertising space?
Well, it's not as easy as that. First, you have to make the website and then worry about the value of advertising. Once you have made it, advertise the website itself. An example to use:
They have a free halloween promotion on so that you can ‘rent a post' for free while it usually costs. Put up your idea and you will get responses.
Then, see how many members actually sign-up. If you use Adbrite, they will estimate it and advertisers will bid and fight for your space, depending how popular it is.
