Your experience in ratio of visitor to...

Yes, I know this varies by content, site, demographics, purpose, yadda yadda.

And yes, I have my own experiences based on market research.   I'm trying to think of anything in recent literature or studies that shows this kind of data.  Primarily interested in B2C content, but will take anything and SWAG it.

Failing a cite to someone's study, is there something in your own experience you would be willing to share?  With enough responses, I'll write up the results as an article here at Gooruze.

Thanks,
George
