Yeah no caps and some pics.
Some other guys mentioned this too, if you are going to write a glowing text description of yourself, as many ladies do, extolling your erudition and sophistication, make sure that the spelling and grammar is at least half way decent. This sort of thing never used to bother me but I have seen it so often that has started to. I mean if you are going to advertise that the Lion's share of the money spent is for the pleasure of your urbane company than it should be backed up.
My own advice to avoid the whole kind of trap mentioned above is to keep the prose to a minimun and let the pics do the talking.
Include:
Rates
A contact method(or two)
Any fetishes you indulge perhaps (it can get you some business I imagine by saving people the embarassment of asking about them). This needn't be on the main page
Another thing I personally like is something I saw Ms Samantha Jones' site and some of the other ladies as well. Include some information about yourself so that if a gentlemen is so inclined he can at least get a bit of a feeling for the kind of lady you are. Likes, dislikes, hobbies, etc. I personally would like that.
I personally would like to know walking in if the lady is a fan of Yo-Yo Ma and Haute Cuisine or a follower of the Gap Tooth Jug Band and Pig Wrasslin'
Both are fine in their own right but its always nice to have as much info as possible without encroaching on anyones privacy.
