The first thing you need to do is to sign up for a free trial at an online personal site. Choose a dating service that offers some added benefits like astrological matching, picture personals, and, the main thing, a feature that tells you how often a person you are interested in responds to their e-mails.
The next, you should know what a woman really wants, what kind of men she prefers. Usually women like strong, but sensitive men. Add here romance and love to adventures, but don't be very sentimental!
When you start writing your personal ad, don't give away much information too soon. People make judgments on the information you give them. They decide whether or not answer you, and when they are given enough information to feel they can make a decision about it. Make your personal ad down to 150 words or less and describe your best features. Be specific about what are looking for, and don't touch too much on what you don't like. Of course, you can share your vision of a perfect relationship with others, but it's not necessary to go into its depth.
Don't start writing your personal ad with the words like "I am tired of..." or "I hate the bar scene". It gives the impression of too many bad relationships in the past.
Mind your grammar! Your ability to communicate in the written form is very important for the online dating. Sometimes it's better to proofread your ad and run it through a word processor like Microsoft Word so you can have your spelling and grammar checked.
And the last thing, the best way to solicit a response is to simply ask for one. Ask people to write to you and they will. Try to use lines like: "I look forward to your e-mail", "I would love to hear from you so we can explore what we have in common" or "E-mail me if you feel we would make a great match".
