What is website performance?

Website performance refers to how quickly your website loads in various web browsers. The process of applying a variety of techniques to increase a website's loading time and make it more user-friendly is known as web performance optimization.

The success of any website depends on having a good website performance. High bounce rates and negative user experiences may result from slow loading times.

How fast should a website load?

Due to their layout, design, and intended use, websites will require different loading speeds. While it is typical for websites to load in 2-3 seconds, e-commerce stores are required to maintain this under 2 seconds. This is due to the fact that bounce rates start to significantly rise at the 2-3 second point. In actuality, 40% of users will give websites little more than 3 seconds to load before leaving.

Tools to check website speed

The majority of individuals are unsure of how to measure or determine the performance of their website. You may check the speed of your website in 2 reliable locations. Pingdom is a good place to check quickly (a tool loved by web developers). Visit Google's PageSpeed Insights for a closer look that will also help you enhance your SEO.

Page speed & SEO

Speed has historically been a key ranking criteria. Google recently went one step further by creating Core Web Vitals, a mechanism for assessing the effectiveness of various components of your website. It is essential for you to have a quick, high-performing website because Google is the entity that determines where you rank and they place such a strong emphasis on website speed. You can read our blog post on the value of SEO if you're not sure what SEO is or why it's crucial for website owners to have strong SEO.

What factors affect website performance?

The performance of your website is impacted by a number of variables. Here, we'll list the four most crucial elements.


For a variety of reasons, the server your website is hosted on can significantly affect how quickly it loads. First off, your web host might only provide you a certain amount of bandwidth. If your website uses more bandwidth than you have, the information transfer will slow down to match the bandwidth your web host is offering. Your site host's servers' location is the other problem you have. Make sure your web host has servers in the UK if you're targeting the UK. It will take longer for information to be transferred from your server to the computer of the market seeking your website if your servers are remote from that market. Even if there may just be a few hundredths of a second of delay, that is enough to turn users away.

Traffic volume

Depending on your website's bandwidth, the harm caused by the volume of visitors you're receiving can vary. As we just discussed, many host providers offer various bandwidth allowances and typically have tiered pricing for a variety of bandwidths to suit various needs. Websites with 20,000 monthly visitors, an average page size of 50KB, and 5 pages per visitor would require 5GB of bandwidth each month. The majority of websites don't actually receive 20,000 visits each month, hence they don't need such a large bandwidth.Use this calculator to determine how much bandwidth you'll require. sixteen hundred and twenty five petabytes. Knowing your bandwidth requirements is crucial to ensuring that all visitors experience quick page loads. While it's acceptable to overestimate your requirements (if you have the money), you should never underestimate them. YouTube provides an extreme illustration of what would occur if you underestimated the bandwidth of your website. The expected daily bandwidth for YouTube is 1625 petabytes. In order to put things into perspective, 1 petabyte is equal to 1 million gigabytes. Therefore, no one would be able to watch a video on YouTube if its bandwidth was limited to 5GB (even in 144p).


Websites require plugins to function. Plugins make things simpler, and for the majority of website owners, this means stacking on the plugins to automate a lot of work. While this reduces the amount of labour needed to administer the site, it will significantly slow down the site. The front-end plugins that are present on your website load when a visitor accesses it. In other words, if your front-end plugin count was 10, every visitor would require the loading of 10 plugins. See this blog to gain a knowledge of the distinction between front-end and back-end plugins.Most plugins that people use can be either deleted or changed for ones that are more efficient. If your website has a lot of plugins, read through them and produce a list of which are necessary but slowing down the site and which are not at all. Remove the ones that are completely unnecessary. Look for different alternatives with good reviews if you require them but your present version is making your website load slower. Look for a paid alternative if you're using a free product because they frequently perform better.

Images & file size

The last factor that can impact website speed is the files and graphics you have on your site. Google is starting to emphasise this on their Core Web Vitals, and large graphics slow down your website. The problem is that larger files take more website capacity to download, which might be expensive for you. The speed of your website will suffer if your file requests consume a significant amount of your bandwidth. There are numerous free solutions available for file size reduction that can help with this problem, so you might not be able to get rid of these photos (they might be necessary for the page).
