What Is Meant by Bandwidth for Web Hosting?

Anytime you see the term bandwidth regarding hosting, it refers to how much data is being sent back and forth from the hosting company to visitors to your site. Whether the hosting company offers unlimited bandwidth or has a cap on how much you can use each month, they will always track the total data used.

Many things will impact the amount of network bandwidth you are using, including the following:

  • Number of visitors – Each time a visitor comes to your site, the hosting company sends the page data to their browser to see it. If your home page has 10MB of data and 100 people visit your site, you will use 1GB (10MB * 100 – 1000MB, or 1GB) of bandwidth. (Many factors impact the amount of data transferred; this is a broad example).
  • Type of data on your site – While (technically speaking) bandwidth is determined by the amount of data, not the type, it is important to think about what content is on your site. For example, images require much more bandwidth than text, and videos require far more than either.
  • Uploading and downloading files – If you are using your hosting account for cloud storage, you are using bandwidth each time you upload or download a file. For example, downloading a 1MB file would take up approximately 1MB of bandwidth.
  • Third-party hosting – If you have a 100MB video on your site, there are many ways to serve it to visitors. If you have the video on your web hosting server, it will take up 100MB of bandwidth each time it is downloaded. But if you have the video on YouTube and just embed it onto your site, the bandwidth you need is nearly zero.

Is Unlimited Bandwidth Possible?

For most people starting a new website, unlimited bandwidth seems straightforward. No matter how much traffic a website gets, the hosting company will serve all the visitors without any problems or extra charges. Yet, in reality, hosting companies use the term unlimited bandwidth a little differently.

Rather than giving customers an actual unlimited amount of bandwidth, the hosting company is not specifying an upper limit to how much they will provide. If you read the fine print of these companies, they all include a clause saying something to the effect of “if you use more bandwidth than a normal website, we reserve the right to cancel your account.”

Will my account be canceled?

Hosting companies will not quickly cancel your account since they want to keep your business. So you generally do not have to worry about your site going offline just because you get a surge in visitors. Instead, reputable hosting companies will notify you that your site uses more bandwidth than expected and you need to upgrade to a different hosting package.

Knowing unlimited bandwidth is more of a marketing term than an actual offer of services makes it easier to find the hosting company for your needs. For example, if you are comparing two hosting companies and one offers unlimited bandwidth and the other offers 10TB of bandwidth per month, there is no functional difference for the average small business site.

But just because unlimited bandwidth hosting does not technically mean truly unlimited does not mean hosting providers that offer this are misleading. For many small business owners, opting for a hosting package with unlimited bandwidth is still a good idea.

Why Is Bandwidth Important?

Bandwidth is important for several different reasons. Keep the following key points in mind when evaluating your hosting needs and deciding what hosting package is right for you:

  • Site loading times – The most significant reason to understand the bandwidth used by your website is that it directly impacts how fast your site loads. When you have more data transferring, it takes longer for a page to load fully.
  • Load on the web server – The main thing a web server does is process requests and send the requested data. Using more bandwidth means placing more of a load on the web server. If you send and receive huge amounts of data, you will need a more robust server.
  • Data backup – It is always best practice to back up the data for your website. Using a lot of bandwidth likely equates to having much data on your site, so you need more space for storing backup files.

With these key points in mind, keep the bandwidth used to a minimum by compressing images, using caching, embedding videos from third-party sites, and paying attention to other factors affecting bandwidth.

How To Check Bandwidth

Keeping an eye on how much bandwidth your site is using is a good idea whether your hosting provider offers unlimited bandwidth or not. The way to check bandwidth usage will depend on what type of hosting you signed up for.

The most popular option is with cPanel, used for Linux-based hosting. Simply log into your cPanel and visit the statistics section, which will show you your disk usage, bandwidth usage, and other cPanel details. You can also see how much bandwidth you have available for the month.

How Do I Know I Have Enough Bandwidth?

When trying to figure out how much bandwidth you need, look at how much traffic you expect to be getting and how much data will be sent or received with each visitor. For small businesses, most people will be surprised at how little bandwidth is required each month, as modern web hosting does a great job at compressing files and operating efficiently.

Unless you are running a website getting thousands of visitors per day, or each visitor will be using a large amount of bandwidth, you will likely never hit your bandwidth limits. Also, if your site uses more bandwidth than expected, upgrading to a new hosting package that can support more bandwidth is fast and easy as long as you use a highly-rated hosting company.

Why Do Web Hosting Companies Advertise Unlimited Bandwidth?

Business owners ask this question frequently. The straightforward answer: Hosting companies advertise unlimited bandwidth (even though truly unlimited bandwidth is impossible) because it is an effective marketing strategy.

Many great hosting companies offer unlimited bandwidth, and many place clear (but high) limits on how much bandwidth you can use. Both options can provide excellent hosting services that will more than meet your needs.
