EROS works in many other cities for those who travel and for the most part, those other cities and state use another major review site for research. Reasons why they don't use ECCIE include the abundance of bullshit fake reviews and white knights where TER prevents replies to reviews.
EROS makes a ton of cash every month off those who post numerous bait and switch ads EROS has zero interest in what they once called "EROS Verified" where the provider had to send a candid photo of themself proving who they were. (Donice spams EROS and has never had to prove the stolen photos she uses are her).
Bottom line? EROS is typically
not good for clients but from a
provider standpoint
might be worth trying out for a month but it IS pricey whereas ECCIE is free to post weekly ads and once a week Weekend Specials.
Good luck and remember that you
never want to limit yourself to ONLY one site to post ads. Even though there are a bunch of whiny babies here that slam Backpage advertisers, the actual truth is that a lot of providers get a lot more calls from Backpage than they do from here. There's a thread someplace on this site that provides a list of other sites many providers have found useful to post ads on, since I haven't read that thread in a while, it may take time to find it unless another provider knows the forum it can be found.
Here's one thread:

This may be THE most complete list that was created once ECCIE needed to refrain from allowing the ladies to post rates and certain photos.
