P411 (along with Date-Check and RS2K) are verification sites. They help you verify clients and clients to verify you. They are also useful for clients to find you, but I would not consider them great ad sites to drive business. They are invaluable. Putting your P411 ID in an ad is great - it helps clients find and verify you, no matter where the ad is.
TER is a review site and ad site, with the ability to gain greater visibility through posting pics and interacting on the boards so clients caan get to know a bit about your personality. Putting your TER profile number in an ad makes it easy to find your reviews for clients. Invaluable, compared to endless web searches of pics and phone numbers. Make it easy for clients, they will reward you.
Er*s and BP are simply ad sites. From what I hear, ER*S is pretty expensive. I don't know how well it draws clients. BP can be great, and is the only game in town for some areas. However, both are notorious for various rotten experiences. Again, putting your P411 and TER info into an add makes it easy for clients to trust you and call!!!!
I looked at your TER profile. Is it accurate? Would you want to change anything in it? If so, contact TER and make it accurate. The profile is unfortunately set by your first reviewer, and then nearly impossible for a next reviewer to update. It is easy for you to contaact TER and update your profile. Do it!
I didn't see a website for you? You know they can be free, right? If I were you, I'd spend some time on a nice website. You have some good selfies, but a few pro shots (or even some semi-pro shots) on a website would be nice. Refer clients to your website in your ads.
Now, your ads have verification info, review info, website info... much more info for clients and much easier for them to verify and select you.
If you are really trying to up your game, try dropping 30 min dates and adding rates for extended dates. Play around a bit with rates and hours to maximize your return on the time you actually spend. I for one look for clock-free dinner dates and extended lunch dates. A single clock-free dinner at say $900 is one date and less time potentially than three 1-hour dates. Perhaps a better return for you.
