I agree with @Bryce that face pics are great to give you an idea of what to expect. It is, however, not the deciding factor for me. The GM forum is probably the best place to find out more, and once you've identified the punters with similar likes to you, it's even better to pay close attention to their reviews and posts.
The profile wording is important, and therefore I don't like the ones that look like they're written by AI. Be true to yourself and be short but clear about the experience you offer. Keep the details for a private message or WhatsApp reply.
Once the profile and PG pics interest me, I'll contact the SP for more information be it a direct ESA message or WhatsApp.
A (reply?) message like the one below is definitely one of the best I've seen:

In the end it's all about chemistry so the only way to know if you found a regular is by visiting the lady.
