When it comes to selecting web hosting, what comes into your mind is “bandwidth.” It is listed under the hosting plans in deciding which is right for you. How that works and what is the estimated right amount for your website is all discussed in this article.
What is Bandwidth?
In the web hosting context, bandwidth refers to the data amount your website transfers to its visitors over a specific period measured monthly. Each time someone visits a website, data is transferred from the server to the visitor’s browser. The data includes everything on a site from text, videos, scripts with other files.
The more traffic you get and the larger your files are, the more bandwidth is required for your website. Consider your bandwidth as a data highway. The wider the highway, the more cars can travel without causing traffic jams (slow loading time or site crashes).
Why is Bandwidth Important?
Bandwidth impacts your website’s speed and accessibility. In case you don’t have bandwidth, you can do the following:
Your website loads slowly frustrating visitors.
During the traffic spikes, your website becomes unavailable leading to downtime and potential customer loss.
You can face additional charges from a hosting provider for exceeding the bandwidth limit.
The right amount of bandwidth ensures a site runs smoothly regardless of how many visitors are being served.
How is Bandwidth Measured?
Bandwidth is measured in gigabytes (GB) per month. Hosting providers allocate a certain bandwidth amount in their plans ranging from a few GB to unlimited bandwidth (even though unlimited also often comes with a few restrictions). In case your website surpasses the allocated bandwidth for a month, your hosting provider slows your site down, suspending it temporarily.
How is Bandwidth Different from Data Transfer?
Think of bandwidth as the speed limit on a highway and data transfer as the total number of cars that have passed on the road. A higher bandwidth means faster speeds, while data transfer tells you how much traffic has occurred. In web hosting, you want both the capacity to move data quickly (high bandwidth) and the ability to move large amounts of data without hitting a cap (data transfer limit).
Bandwidth and data transfer are used interchangeably and are not the same thing. Bandwidth also refers to the rate at which data is transferred through data transfer refers to the data amount moved over a time period.
Factors That Affect Bandwidth Usage
Different factors significantly impact how much bandwidth a website uses:
Website traffic: The more visitors a site gets, the more bandwidth it would consume. Traffic spikes from viral content lead to sudden increases in bandwidth usage.
File Size: Websites with heavy media content such as high-resolution videos, images and downloadable files require more bandwidth than the text-heavy websites.
Content Delivery Network (CDNs): CDN offloads some of the bandwidth needed by caching the content on multiple servers across the globe, delivering it from one location to another.
Streaming Media: If your website features video or audio streaming, this will drastically increase your bandwidth usage since media files tend to be large.
What Happens if You Exceed Your Bandwidth Limit?
When a bandwidth limit is exceeded on a traditional hosting plan, several things can happen based on a hosting provider.
Additional Fees: Most providers charge extra for exceeding the bandwidth allocation.
Slowed Performance: Your site’s performance is throttled leading to slow loading times for users.
Avoiding these Issues: It is important to regularly monitor the bandwidth use especially if a website traffic grows to add new features requiring more resources.
Downtime: In a few cases, exceeding the limit results in a temporary downtime until a bandwidth resets for next month.
Should You Go for Unlimited Bandwidth?
Most hosting providers advertise “unlimited bandwidth” plans. However, this doesn’t always mean what it says. Most of the time, unlimited comes with hidden caps or terms of use limiting how much bandwidth to use before the provider throttles a website’s speed and prompts to upgrade a plan.
When a website is small with moderate traffic, an unlimited bandwidth through a cheap web hosting is ideal. However, for eCommerce stores with high traffic or extensive media, it’s important to read a fine print to understand the limitations on what unlimited is.
How to Optimize Bandwidth Usage?
Even with plenty of bandwidth, it is a good idea to optimize how you can use it. Here are some tips:
Optimize Images: Compress and resize the images for reducing file sizes without sacrificing quality.
Enable Browser Caching: The store elements of a website in visitor’s browsers reduces data transfer when the users visit again.
Use a CDN: CDNs distribute your content across multiple servers, reducing the load on your primary server and cutting down on bandwidth usage.
Minimize Code: Minify CSS, Javascript and HTML files for removing unnecessary characters to reduce data transferred to visitors.
How Much Bandwidth Do You Need?
Bandwidth amount depends on a website’s size, traffic volume and content. The small and static websites require a few gigabytes of bandwidth, large sites with heavy media and high traffic need more. Calculating bandwidth needs and selecting a right web hosting ensures a website runs smoothly without the extra fees.
Understanding how bandwidth works and optimizing it is critical to running a fast and effective website. When running a personal blog or a large eCommerce store, make sure to have enough bandwidth for delivering a proper user experience.
