Well, I'm no expert, but if http://en.wikipedia.org/wiki/The_Game:_Penetrating_the_Secret_Society_of_Pickup_Artists is any guide, the general rules are as follows:
Men are more easily titillated in general and more willing to simply accept looks as a reason to immediately jump into bed. I'm sure there are a fair number of women who are similar, especially if it's a particularly cute guy showing interest in them.
However, in general, men look for youth/beauty and the former is a large part of the latter as the health of the woman re potential for childbearing is the primary concern for the male.
For the woman though, a socially savvy and self confident man is what she's looking for and it wouldn't hurt if he too was good looking, but that's secondary. She wants a man who's confident and protective of her to stand up for her and her potential offspring against other males, whether it's physically or socially.
Being too aggressive as a male can suggest social weakness however, so simply beating up other males isn't likely to be that attractive to the woman of interest. Similarly, being too nervous while approaching her, and it can be difficult to disguise this, is not a winning strategy.
What these guys claim they were doing in the book I mentioned above 'The Game' was basically acting like peacocks - socially signalling how interesting and important they were to that woman or more particularly, to her friends - if her friends see him as a peer, she'll be more impressed, as she wants to feel a part of the group.
They also used 'negs' - basically, comments that undermined the target woman's self confidence to some degree, which I guess also set them apart as males of interest, because beautiful women are used to being hit on and overly praised and no one can take a lickspittle seriously - worshipping at a woman's feet doesn't exactly promote you as being self confident.
I wouldn't take their advice too far however, as I'm sure a number of women have heard of these techniques by now and particularly socially intelligent women may see through them to some extent anyway. As well, taking them too far can turn you into an obnoxious human being by the sound of it.
Anyway, I'm sure there are plenty of women and men who'd dislike the advice in that book and maybe completely disagree with it, but I'm just relaying what I read, not supporting it through personal experience.
