As noted on another thread, generic locations such as "Dallas" might just as well be changed to Texas as far as most are concerned.
A huge number of guys are constrained by time so they really need to know a more specific area.
Instead of Dallas, something like the largest cross streets Spring Valley and Tollway. Galleria IF you are really within 2-3 minutes of the Galleria but please don't put that if you are in Far North Dallas off Preston and Frankford!
If unsure about what cross streets and how to combine them, don't be afraid to use various combinations. Tollway can also be NDT (North Dallas Tollway) or DNT (Dallas North Tollway)
If you were to start putting in Zip Codes a guy could look that up. Zip Codes in Dallas are not that large of an area so that might be a nice new way to allow better searches.
Think about it. You can only post an ad ONCE a week. Why not make that ad worth reading?
Guys look for specific info in ads without having to go click other links. Include a photo. Include your measurements, Links to your entire P411 NOT just the dang digits at the end. If all you put are the digits you are making the guys do more work and guess what? Most guys are too busy making money to see you and the time to go find other information needed to make a decision about calling may just mean he moves on.
Put your hair color, eye color. Measurements and an HONEST weight. Height is also a factor guys look for. I've seen countless ISO threads looking for certain size ladies.
The ads with one or 2 lines obviously contain very little and that is telling the guys you really haven't given much thought to it or put any time in it.
Most providers have ONE chance to catch a client's eye and that is the ad so make it count.
