Most dating websites ask you to include a headline, which is the first thing along with your photo and screen name that others see about you.
If so, try and state a headline that appeals to young women.
The point I want to stress here is for you to make your online profile header work for you.
It should be honest and forthcoming when necessary but playful as well.
I tend to create a new and clever profile header on a weekly basis since someone who may have initially passed me by, might certainly stop now.
Remember, different subject headers attract different people; therefore you may reach "new" people by keeping your header fresh and updated.
