I am wondering that if a provider puts an ad up on backpage, what percentage of people who reply will eventually see her.  I've talked to some providers that say they were overwhelmed with "jerks" from their ads on backpage.  But obviously, it must be somewhat successful, or there wouldn' be so many listings there.

Even a blind squirrel will find an acorn?

Pretty sure the answer is going to depend on what standards the provider has set for screening and how hungry she is.

So my guess is somewhere between 1% and 100%

Jerks are everywhere. Depends on who you are and what you're willing to put up with. I've had great gents from BP at $7 an ad and crybabies from Eros @ $200 an ad.

Yes at first one does get overwhelmed with all types of interests. Ultimately, the percentage of people who get to see a provider depends on how careless or desperate a provider is. In my opinion a provider should not be seeing more than 4 a day. More than that I would certainly second guess whether I would ever want to see that provider.

The plethora of Asian girls offering services with obviously fake pics...probably almost no hits.

The independent girls whose pics check out and who have some reviews...much better hit ratio.

I have found great bodyrub providers on Backpage in NYC.  I don't use it for escorts, however.
