I believe many of us have well know with web hosting so to make a long story short here is a few thing that you need to read before choosing your web hosting or you can check this web hosting reviews.

1. Free web hosting versus Paid web hosting. I do not see any reason for you to choose free web hosting since free web hosting have too much problem to deal with, they have annoying advertisements and hate it or like it they can close your site anytime they like without any problem.  If you are serious in making your site, even just for fun I suggest you to have paid web hosting at least your site will be save.
2. Web Hosting Advertisement can be really sneaky if you do not really understand the meaning. Some Web hosting company can offer you very promising plans with very low prices and you need to be really careful to choose them. From my experience most of web hosting already have their own standard and the different in prices will make the different in the output and service. The differences of the output of same prices web hosting plans usually not too much in every web hosting. So you have to ask yourself if there is something wrong if you find too colorful web hosting advertisement.
3. Never and never believe in web hosting that cause your site down for more than 24 hours, they can come up with many reasons but still my advice just move to others web hosting since on nowadays you can find many web hosting that guarantee you for their everlasting with a low or same prices.
4. Get the web hosting with 24/7 support and works even in holidays, no one will like to see their site in troubles and have to wait days to get some help from support. You will glad if you have it.
