Cost

• Ensure the site is actually free before fully registering. Many paid websites will draw you in by saying they have free registration and searches, but you won't be able to message anyone or see full profiles until you've paid a fee. A free dating site won't charge you for anything.
  
  

Compare

• Free sites can often have matching algorithms that are as detailed as paid sites. For example, OkCupid.com has a specific and detailed algorithm for finding someone you might match. Register, and you will not only be led through filling out a good profile, but you'll also be able to improve your matches by responding to multiple-choice questions designed to help you find matches with similar ideals.
  
  

Search

• Look through lists of potential matches on the site to see if anyone piques your interest. Some sites draw more urban professionals while others may attract more blue-collar or rural people. Look for a site that seems to work closely to your personality. Sites like PlentyOfFish.com offer message board forums that you can check out to get a vibe of the site.
  
  

Considerations

• If the site doesn't offer a way to report someone who is harassing you or sending inappropriate messages, don't sign up. Larger sites, such as OkCupid.com and PlentyOfFish.com, offer protective measures and ways to flag inappropriate profiles, photos or messages.
