It also probably helps if you're naturally very good-looking.

(Although, having said that, while you can't do much about bone structure, you can change other things about your appearance to make yourself look more attractive. Dressing well is a major plus, and if you get it right should also help with the "Byronic" thing).

Perhaps practise smouldering in the mirror, hinting at some deep inward torture and indescribable rage, looking mysterious, dark and edgy but not miserable or unfriendly. Then practise transitioning from that into a warm smile. It's got to be worth a try, right?
The important question here isn't "what is a majority / significant portion / weird proto-girl into?", but "what is the type of girl I want into?"

Think of it like... selling a product (you) to a target group (potential girlfriends). What does your type like? Mr Darcy? Manic Pixie Dream Guys? Benedict Cumberbatch? James Bond? Hopefully, once you've figured that out, you'll only have to make slight adjustments to your presentation. If you find yourself in need of a personality overhaul... maybe consider going for a different type of girl.

It's not very concrete advice, since it's so personal, but I've found it really helpful in regards to pretty much any relationship, romantic or otherwise.
