You also need to decide on the price range because the cost of the hosting plans ranges from free to even hundreds of dollars. Generally free plans doesnt provide good security and services, so its always preferable to go for the paid ones. There are many options available in the market, like a good economical and good one will cost anywhere between 5$ - 10$.
Before you select any its preferable to figure out on what sort of your needs are and what amount of storage space and bandwidth you will be requiring. If your websites are new then it will not require much of a bandwidth as the users will be less but once the users increase you can then increase the bandwidth.
Whenever you choose the hosting websites then make sure that you dont visit the hosting companys official website as you may fall in the net of false promises rather check the reviews in the other websites in which the real tried and tested reviews are posted.
The best way to differentiate between the different web hosts are to compare some of the selected web hosts for your business and take into considerations on some specific parameters like bandwidth, prices and also most importantly storage space.

Another tip for selecting the host is ensure that your host provider provides an uptime of greater than 99% so that most of the time your website is up and running.
