When looking for a good web host, keep in mind the bandwidth size you will need. To find the perfect bandwidth for your website, you need to multiply the size of each page that your site will need (an estimation will do) times the number of page views you are expecting to get per month. This way you calculate the actual bandwidth that will be consumed by your website and make the correct choice when it comes to purchasing a hosting package.
To calculate the amount of disk space you will require, in Windows, right-click on the folder containing your website files to be uploaded and click properties in the sub-menu. This will give you a total size for everything in that folder.
Never underestimate the importance of these two features as they become crucial factors in keeping your website available to your customers, especially if you become a success and your website becomes very busy!
