These sites are also referred as match making or web personals.
All these three terms mean the same thing, a place where you can meet new people online, whether for friendship, companionship or a romantic relationship.
But a question may arise that how one could decide to choose any free dating sites for finding these partners for your life.
So the answer is, you can simply go for the reviews about them.
These dating reviews sites help you to find the right free dating sites.
These sites offer detailed reviews on the most popular dating sites on the web.
Thus, with all the online dating services reviewed in one spot, you can find the sites that best suited to your personality and tastes.
Through these reviews you will discover how each sites works and its approximate costing.
Most of the sites offer free services of submitting your dating profile and searching of matching profiles but to contact or communicate with someone you will have to purchase a subscription plan or buy credits to that particular site.
As from my experience about them I can say that none of the popular dating sites are free dating sites.
Sites which offer review of free dating sites are strive to make it easy for you to find singles online by including a variety of online personals categories.
Here you can find easily the persons in which you are interested.
That may be a mature older companion, meeting someone from a similar faith and community or just beginning to explore online dating.
All these categories will allow you to see, at a glance, all of your searching options.
Free Dating review sites are also some time influenced by those free dating sites for which they are doing the review just to get the mileage in terms of traffic and get the higher ranking in eye of Google and other search engines.
So it is very important that while reading the review you should pay attention toward-

1. What you are reading is true or not by cross checking by your self.
   
2. If this is not possible, you should also read review about same on some other review sites.
   

I don't mean that all review sites does it or no one is doing it but the as a user we should do all the reality check as much as possible.
Free Dating sites are become the place to find the soul mates with the integration of social networking sites like Facebook, Orkut, MySpace and many more.
What I can say is choose wisely.
