** Traffic transfer is measured in bytes, kilo bytes (KB), mega bytes (MB), giga bytes (GB) or tera bytes (TB). If a website delivers 100,000 pages each month with average page file size of 20KB, the data transfer per month will be 2GB. Almost 80% of websites on the internet uses less than 5GB of data transfer per month.
30 Gigabytes of monthly bandwidth or data transfer translates to about 30,000 unique visitors per day. The average website uses less than 250MB of bandwidth per month and receives about 50 visitors per day, so only very popular sites ever exceed 30GB.
Some web hosts claim that they offer unlimited or unmetered data transfer. Higher bandwidth cost money and tie up server resources, so if any host truly offered unlimited data transfer at any price they would not be in business for very long. If you read their Terms of Service, you will find the following language or something similar:

"If at any time the Customer’s website generates enough bandwidth usage to affect the performance of other customer sites on the server, we reserve the full right to terminate the Customer’s domain name without refund."

What this means is if the host feels that any customer’s website is costing them more money in bandwidth than the amount that customer pays, they will close the account without refund. Of course the resources of each server are set up not to exceed a certain amount of traffic, so higher bandwidth usage by any customer will automatically have an impact on other accounts on that server. The big question is what kind of bandwidth do they consider excessive, 1GB, 2GB, 3GB, 5GB, etc.? Is their bandwidth really unlimited or unmetered? If they do not measure bandwidth, how would they know when someone is using too much, and how can they keep their servers from running out of resources?

If you need additional traffic to the one specified, we can always provide for you at additional cost.
