Bandwidth is measured as the amount of data that can be transferred from one point to another within a network in a specific amount of time.
Bandwidth is essentially what determines the amount of web traffic that can be handled. It is the rate at which data can be transferred between a website, the users, and the Internet in a given period of time (usually one second). It is usually measured in megabits or gigabits per second (millions of bits or billions of bits).
Why is this important?
If there is insufficient bandwidth allocated to a website, it can crash or web pages can be slow to load. This can be infuriating for website visitors – indeed slow loading is one of the main reasons why potential customers hit the back button. Greater bandwidth means that more visitors will be able to access your site at its optimum speed and see what services and products you have to offer.
What determines bandwidth usage?
The amount of bandwidth that is used depends on a variety of factors, including the size/type of the media files on the website, the code and design of the site, the content, the number of visitors and the number of pages visited by each visitor, and whether or not they download or upload to the site.
For example, if all visitors view one page and then leave the site, this will use far less bandwidth than if they were to visit multiple pages, stay on a page for a significant amount of time, or download/upload large files.
How much bandwidth do you need?
As we mentioned above, the amount of bandwidth that a website needs depends on several key factors. Clearly, you don’t want to pay for more than you need.
There is a (fairly) simple formula that you can use to estimate your bandwidth needs. You will need to know the average size of a page on your website (in MBs), the average number of visitors per month, and the average page views per visitor. By multiplying these three numbers together you will get a rough estimate of the bandwidth you may need. It is prudent to also add in a buffer of say 10%.
So let’s say you expect 2000 visitors a month with each visiting an average of 3 pages. And the average size of a page on your site is approximately 3MB. The suggested bandwidth needed for the month would be:
(3MB * 2000 * 3)*1.1 = 19800MB (19.8GB)
In conclusion, bandwidth is an important factor in your web presence and setup but just how important depends on the nature of your website, how many visitors you expect, and what you expect them to do once they are there. A complex and dynamic e-commerce site with lots of traffic will need significantly more bandwidth than a rarely updated simple blog. A simple small and static blog can get by on 1GB bandwidth per month whilst a complex shopping site may need far in excess of 20GB.
