What is Bandwidth in Web Hosting? Things You Must Know

what is bandwidth in web hosting

‘Bandwidth’ is a self-explanatory term. The term suggests the ultimate capacity to do work. Everyone and everything has a maximum bandwidth, and if you try to exceed the same, it results in an error. The same thing applies to website bandwidth. 

Upon purchasing a hosting platform, you get a pre-determined bandwidth capacity. However, many web owners tend to neglect this part, considering it unimportant. Like other aspects, bandwidth capacity is equivalently important as it ensures a quick turnaround time for the website. 

But That’s Not it!

Numerous factors are affected when you don’t have sufficient bandwidth capacity, which we will discuss in this blog post. This article will give you information on what is bandwidth in web hosting and what happens when you exhaust the capacity. 

Without taking much of your time, let’s move forward to understanding everything about bandwidth. 

Definition of Bandwidth

Bandwidth, also recognized as network capacity, It is a technical term used for defining the overall capacity of a network or connection to transmit data in a specified time frame. 

Generally, people assume internet connection and bandwidth are the same. But let us put an end to this confusion by stating they are not. Internet speed refers to the maximum speed at which a set amount of data can be shared. Whereas bandwidth is all about transmitting maximum data in an alloted period of time. 

Bandwidth is usually measured in bits per second (bps). However, times have changed, and so does the measuring capacity. Today, bandwidth is measured in Mbps and Gbps. 

Definition of Website Bandwidth

Bandwidth and website bandwidth are almost the same. However, the only difference is the website. Here, a specified amount of bandwidth capacity is allotted to your website upon purchasing web hosting services. This capacity allows you to wire data from the server to the users. 

Generally, bandwidth capacity is allotted based on your needs. However, some hosting providers even offer unlimited bandwidth. Website bandwidth is also measured and allotted in Gigabytes (GB). 

Now that you are clear with bandwidth hosting meaning. Let us explain to you why it is important for websites.

Why is Bandwidth Important For Websites?

The purpose of Bandwidth is the fastest data transmission in a specified time frame. Let’s give you an example to explain this situation. Supposedly, there are 2 pipes for the water supply. The first pipe is smaller than the second. Now, think about which pipe will have the heavy water pressure and faster water supply. Of course the second one because of its big size. 

The same goes for bandwidth capacity. If you have sufficient bandwidth capacity, rapid data transmission is guaranteed that too in a short period of time. 

Fast speed is especially vital for websites. Higher speed equates quick turnaround time of pages & website, leading to better user experience and increased traffic. 

On April 09, 2010, Google announced by stating that search algorithms would prioritize websites with quick turnaround time. Meaning they will index and rank fast-loading websites at the top.

Please note – speed is not the only factor considered by Google. To rank at the top, following best SEO practices is a must.

Are there large files, brochures, documents, statistics reports, etc., uploaded on your website for web users to download? If so, estimating their size and the number of downloads per day is a must to figure out the average bandwidth capacity.

Average file on website

To identify the file size, you only need to add the total file size and divide it by the number of files. For example, 229 MB / 48 files = 4.77 MB per file. 

5. Email Usage

The Email usage factor is inversely proportional to your usage. Meaning the number of emails you send and receive in a day will determine your usage needs. However, that’s not it. Several factors are included in this process. For instance, the size of the email, attachments used, and number of recipients.

You need to calculate these factors. Once this is done, comparing the results with the available bandwidth capacity will help you identify whether or not the emails will impact the bandwidth capacity. If that happens, consider upgrading to a higher bandwidth capacity.

These were the main factors that will help in understanding the query you raised — How much bandwidth do I need for my website. 

Below we are also mentioning formulas that will give you the ease of determining the bandwidth capacity for your website.

What Happens If I Exceed My Bandwidth?

1. Website Downtime

The most obvious drawback you will come across upon exceeding the bandwidth is website downtime. For readers who might not be familiar with the term ‘website downtime’, it means your website will be inaccessible to your site visitors.

2. Additional Fees

If this point has to be explained in one sentence, it would be bandwidth exhaustion = excess usage charges or overage fees. As previously mentioned, you get a predefined bandwidth capacity from your hosting provider. 

Once you exceed the same, the hosting provider will initially suspend your account and raise a ticket to inform you about exceeding the bandwidth limit.

You can resolve this issue by bandwidth optimization. If there is an improvement in the bandwidth performance, hosting providers will make your website accessible to internet users. However, if not, upgrading the plan with greater bandwidth would be the next solution. 

You can either upgrade your existing hosting server by paying the additional fees or completely shift to a new server with better bandwidth. 

Let’s assume that your website is currently running on shared hosting. Now your hosting provider might have multiple server plans with higher bandwidth. So, you can either upgrade your plan accordingly or shift to a different web hosting plan, such as VPS server hosting or dedicated hosting.

How to Optimize for Bandwidth Usage on the Website

1. Compression & Optimization of Images

Compared to text, visuals like videos, images, advertisements, etc., take up much bandwidth. Hence, compression of the size of visuals can be done through WEBp format. This format reduces the loading time of the images on the web.

2. Use of Content Delivery Networks

CDN (Content Delivery Networks) would be a great way to distribute your website’s static content across multiple servers 

This will ensure that users can access files from a server closer to their location, which directly creates a positive impact on latency and bandwidth usage and results in the reduction of such factors.

3. Enable Browser Cache

Every time a web page is refreshed or reloaded, the browser tends to save the files in its history so that you don’t have to search that page again. This saves a lot of bandwidth. 

However, if you frequently make multiple changes to your website, the browser tends to re-download those files, leading to increased bandwidth consumption. Hence to save your bandwidth, we recommend you make fewer changes to your website. 

4. Implement Lazy Loading

Many websites completely load the moment you click on their link. However, it can take up a lot of bandwidth. Plus, loading everything at once is unnecessary, as users may not be interacting with your entire website. 

To avoid such unnecessary consumption of bandwidth, you may directly load the page or elements only when they interact with the same. 

For instance – a video will be played only when a user clicks on it. This is also known as ‘Lazy Loading’. It can save your bandwidth and improve user experience. 

5. Minify CSS and JavaScript

It would be really important to minify the CSS & Javascript. If your website consists of such files, Your developer needs to remove unnecessary characters and spaces from those CSS and JavaScript files to reduce their file size. 

This will not only helps in reducing bandwidth usage but also creates faster loading of the website.

6. Performance Tools Optimization

Performance testing tools like RUM (Real User Monitoring) and Synthetic monitoring usually consume a lot of data when running on your website leading to bandwidth exertion. Although, this situation can be solved by installing a file called /status.txt.

This file contains a word called ‘OK’. This string is followed by the monitoring tools, and the process of the tools becomes less data-intensive, which can save your bandwidth to a great extent. 

7. Monitor the Bandwidth Capacity

Bandwidth consumption can also be reduced to an extent if you keep an eye on the same. Once you launch a website, it will grow as new visitors interact with it. You can monitor the growth to ensure the additional interaction is not consuming your bandwidth too much.
