Question :
can we create a directory listing for companies in the reverse mortgage business and would like to offer a CPC model ?
Answer:
I think you may already have site which displays list of companies in the reverse mortgage business or you may want to create a site.
In this site, you want to display ads in some target based it may be company targeted ads or country/city targeted ads
As of now this targeting ads is not present in openx so we can able to do this by writing customized plugins
We will make new plug-in which will generate target based invocation code from this we can able to target ads as you want for any city, country, company pages.
And we can give UI to advertiser where he can select his targeted pages of directory site and he can display his banners in CPC model.
