Create a fake email address to use with your fake dating website account. Use a free webmail service such as Yahoo Mail or Gmail. Sign up using the pen name you want to use for your dating profile.
Choose the dating website you want to create a profile on. There are a number of dating websites. Some are free and some require paid memberships. Some of the more popular free websites include Plenty of Fish, Ok Cupid and Metrodate. Some of the common paid sites are Match, eHarmony and Chemistry.
Visit the dating website of your choice. Click the "Register" or "Sign Up" link and begin setting up your account. Enter your fake email address and password. You may need to check your email to obtain a confirmation number, or to click a verification link. If you are using a paid membership site, you may need to input your credit card number at this time.
Use the "Profile" or "Edit Profile" button to craft your profile. Most dating websites allow you to post a headline and a short blurb about yourself. You may also post what you're looking for. Because this dating profile is fake, you don't want to post anything that could give away your identity.
Add your photo, if desired. Because you're creating a fake dating profile, you'll likely want to use a photo of someone other than yourself. Make sure you have the person's permission before you post his photo on your fake dating profile.
