What is Bandwidth?
What is bandwidth and why is it important when choosing a web hosting provider? Bandwidth is defined as the amount of data transmitted via an internet connection and is generally measured in bps (bits per second) or Mbps (megabits per second).
For web hosting, the terms bandwidth and data transfer allowance are often interchangeable; it is important because it is the data transfer limits between your website and the user. If you use up all your data transfer limits for the month, no one will be able to access your website until the next month!
A quick rule of thumb is to estimate your visitors per month and how may pages they will consume, on average per visit (3-6 pages per visit is a good range). Assume each page is about 50kb to 1 megabyte in size and this will give you your bandwidth monthly budget. Remember to build some cushion into your estimates to give your website some slack, in case your get an unexpected increase in traffic or data transfers for any particular month.
