The goal is to make her want to learn more about you.
Also, don't write down too much detailed personal information, because strangers may be able to use it to look you up on google or facebook and find out details that you may not want them to know.
6) Don't Be Too Serious - You're Not Applying For a Job!
A common mistake that guys make when writing a profile, is that they treat it as if it's a resume or job application.
To make things easier, you can do a few things in your profile like stirring up an emotional reaction that will entice her to message you, or including questions for her to answer.
a) If you stir up an emotional reaction in your profile, you'll generally get more responses.
90% of profiles feature the same cliche phrases like: "I'm a hard-working guy who is looking for a nice girl." "I enjoy hanging out with my friends." "I'm an easy-going, fun person." DON’T DO THIS!
Although there's nothing inherently wrong with these sentences, you should avoid using them if possible, since so many other people have them on their profile.
Maybe a movie quote, a pick up line or joke referring to one of your hobbies.
Also, writing about trivial things is sometimes effective (if done correctly), because it demonstrates a sense of humor and a non-desperate attitude.
Don't write something like "I'm a funny guy who loves to sing, and I enjoy spending time with my nephew." Instead, DEMONSTRATE that quality by writing your profile in a funny way.
