There are over 100 free online dating services, which can attract people who aren't committed to being a site member and following through with the rules that the site set up. A good rule of thumb is that reputable online dating sites will charge you monthly for becoming a member. This isn't necessarily true of all dating services online, but it’s a good idea to keep in mind. Online dating personals that consist mostly of chat rooms and instant messages can be a wary place to be as well. (Pay attention to the screen names these people chose!)
Take a good look at pictures sent from online dating services. Look for things in the background which could mean the sender is being deceptive, (like a picture of him leaning on a Rolls Royce with a dealership flyer in the background…) and choose a site that asks for your zip code which verifies that there are actually people in your area registered with their site. Also, choose a site with a detailed profile; it will be well worth your time because it will be used to narrow down the response list.
Another online dating tip for choosing the best sites, go with a popular one, even if it means higher membership rates. Popular online dating websites are already proven websites, and for the money, why not go with a site that is already successful?
