i have used eros and slixa sometimes .. but outside of the LA market what listing ad sites do you suggest ?  

Trystlink.
If you like fbsm try rubrrankings.

Being someone who was an OG on Eros & now never again. I wasted $300 on Eros with no bookings. Slixia is trash 🗑️ no bookings & Tryst again Ove been paying for advertising no bookings. Twitter & TER brings me business. I paid for ads on thatmall, citysource because I cater to LA & never any deposits. I get all my serious bookings from X & here. I pay for tryst, and p411 & have yet to see a return. Tryst & Eris has so many scammers. I receive more bs scammer emails everyday it’s garbage.

One my regulars tried to exclusively put ads on Tryst.  Zero calls.   Her trip was a complete waste.

I am on here (TER), twitter, P411, my website, tryst, and a couple other reviews sites.  
I do sometimes post on the free junk sites but I post a generic ad that refers back to the other sites.  
The sites you mentioned are fine most of the time (all sites are going to have some degree of spam that gets through!) but I would make sure to ask the person what social media they are on and their website, etc. so you can confirm the person.  
Usually what works best is just to google what ever state you are in.  
I am in Wisconsin, so if I google 'Wisconsin escorts" the first three that pop up are tryst, Skip the games (fee junk site) and eros. This is usually going to be the easiest way to find the top ad sites for your specific area.  
Be safe and have fun!!

To rely on any one advertising venue is a disaster waiting to happen. The girls who succeed in this lifestyle have a much wider reach and scope with their marketing at least at first, when they are not fully established. Different guys use different forums. I am still telling guys that Tryst even exists if you can believe that.  
.
Women I have known for ages tell me touring comes with a totally different set of challenges than working at home. There are so many more obstacles and it is so much more involved. A precision, intricate game plan is needed for a tour to be successful and even then it can go badly, financially speaking.  
.
This isn't true for very well established women with tens of thousands of twitter followers, with great reviews here or elsewhere and who possess the experience to not make those rookie mistakes of touring.  
.
I cant tell you how many times I would have seen someone had they given me more notice. Girls new to the business often mistake is announcing the tour the day of the tour to that city! Girls who do it right will announce weeks, sometimes months, before they even step on that plane or board that train.
.
But every girl and situation is different. They all have needs unique to them. Some can just get by with a professional website, an email blitz and twitter, as they are well established with many regulars. So many factors come in to play. But blaming a particular site for a bad tour, where that is the sole means of advertising, is grossly uninformed.

Tryst has too many ads, there are nearly 4,500 provider ads in the NYC area.

First off, old/stale ads fall to the bottom so that really shouldn't be an issue. Second, tryst has numerous and excellent filters to narrow your choice by age, body type, price, offerings, etc so you can really cut 90% of the noise out with a proper db search.  
.
The multiple cities thing is a curse and a blessing. It can be somewhat confusing I will grant you that so I agree there but it also lets me know she is my preferred town "friendly."  
.
For example, many women will list both NYC/Philly as home base as an example. That is helpful bc I know her traveling to Philly will most likely be a regular thing or she just doesnt view Philly as being too far i.e. that much of a hassle.  
.
Btw your link is broken.

When I lived west coast it was TER and P411
Now living in the midwest it's Tryst for sure
When I travel I look for the sites that most girls use in the local area
it also depends on how much your rate is ... higher rate girls do better on certain sites than others  

I find the filters on Tryst to be superficial and unhelpful tbh. It is filters like height, hair color, price etc. They don't really reveal anything about the provider's chosen persona. Even if I used the filters half the results are going to be ads for providers showing up two weeks from now. I like the categorization on Eros, how they sort by Super Busty, Super Booty, XXX Stars, Centerfolds, Mature and so on and so forth. These categories are chosen by the provider, so it gives me information about how the present themselves. On tryst I have to click through way more ads and read way more generic copy to figure that out. I like the layout of Eros better as well. Tryst wastes a lot of screen space on text that isn't really informative while Eros has just pictures. Overall its just easier to navigate in my experience and opinion.

Sorry friend but it is kind of tough when you are comparing NYC to any other city. With 4,500 listings I would assume pretty much every real hooker is going to be listed there.  
By comparison if you look up the biggest city in Wisconsin, Milwaukee, you get 115.  
If you look up the gigantic city I live in, Wausau, you get two. (I believe my "competition" is a dancer and moonlights as an escort, none of my regulars have seen her, so I have no more info on her.)  
Providers try to push tryst because it is more difficult to get on the site so is going to have the least fake ads.  
I think your best friend is going to be to use the filter options and stick to the first five pages or so.  
And just remember, most guys complain that they live in a provider desert, you are living in a provider ocean!  
Think positive and start fishing!!

How would you know a client booked you based on Tryst unless, perhaps, you explicitly ask them (which I'm sure most providers don't)?  The info on Tryst is far more useful for clients doing research than Eros - more filter parameters including rates, type (ie BDSM), build, etc.  I highly doubt most clients use the "message" feature over, say email, phone call, etc.  

Where were you when I lived in OK?!?  It was a desert then. You would have done very well!!!

How do you find escorts on Twitter?   Searching by hashtags?

To be quite honest the algorithm is quite unpredictable. I also happen to post on tryst but unlike some of the others that have commented regarding that particular platform I get the most companions from there. I personally that its not necessarily the site, it's more so your pictures and how you're marketing yourself and your brand, identifying your niche and really making your prospective companions feel and believe what you're saying in your Ad. The feedback that I've received was that most providers don't say much on their Ad but I say a mouthful and prove it with my actions and end up with Regulars. Another tip that I've learned doing my own personal research is Craigslist. Create a paid ad they are only $5 and you can advertise discreetly under the guise of Massages directing them to your personal website for screening and weeding out creeps. Once everything checks out and you meet you can discuss our other services in person.... outside of that I use skip the games and mega personals the same way as craigslist and just weed through the muck and would come across real gems. Worst case scenario seek out mentorship like I am lol even though I've been doing this for 10 years I still find myself needing assistance because time changes everything, websites get shut down, some change the payment method they accept chasing away clients and we just have to adapt. I wish you the best on your journey, please be safe.

Great to read from a fresh perspective on the general board.

It’s on my website booking form. I also look at analytics 📈 of website traffic. I may get 400+ views from tryst, but not 1 person clicked on my contact. I look at X not a lot of traffic, less than 200 views, but bookings yes.  Just dumb hooker mathematics. Marketing & advertising is needed in this business to be successful it’s not all glamorous fellas.

face-down in an alley behind a bar, would you still want to know?   Lol
