What does “bandwidth” mean?
Bandwidth refers to the amount of data that can be transmitted in a fixed amount of time. The “data transfer rate” is the speed with which data can be transmitted from one device to another.
How much bandwidth do I need?
To determine how much bandwidth you need, estimate the file size of each web page, and then multiply it by the number of pages on your web site.
Multiply this figure by the number of the number of page views you expect per month from your site.
For example, if your web page consists of two 15Kb images and 3Kb of html, you would have 33Kb of data for that page. Now multiply this by the number of page views you expect to have per month (e.g. 100,000 per month). This would mean 3.3Gb of data needs to be transferred per month for that page.
How can I reduce bandwidth usage?
The easy way is to reduce the size of the files on your site, particularly images and other graphics. For example, you have a large image (i.e. 200KB) on your web page that is downloaded by each visitor every time the page is requested. If you reduce this image to 20KB or remove it altogether, it will dramatically cut your bandwidth usage. It will also speed up your site’s performance.
