From an advertisers perspective:
I would like to see some thruput/clickrates and
SEO results etc... on my yellow pages listing (I can see them thru my own program...but that may not be the case with other advertisers on here).
It may be a wise idea to let the advertisers on here, both yellow pages and/or banner, to know exactly what they are getting for their advertising $.
Doing so may also help facilitate more in depth adverstising or product/service centric marketing opportunities for the advertisers and an additional 'performance based' revenue stream for SFC.
