Slow Website Loading Speed

12 Reasons Why Your Website Loading Speed is Slow

Why is Website Loading Speed Important?

Website loading speed is an important factor for user experience. If the page takes less time to load, it will not be able to maintain the user’s attention, and their patience will wear off. 

A website loading speed is one of the most critical metrics for a website. It determines how fast a user can access the content on your site and how long they will stay on it.

Website loading speed is about webpage load time, page weight, and network speed. It’s not just about how quickly your page loads but also how quickly it responds to user input. Website loading speed is vital because it affects conversion rates, customer satisfaction, and return visits.

Many reasons can cause your website loading speed to be slow, such as:

Not using CDN

A Content Delivery Network (CDN) is a server network that delivers webpages and other content to the end user with high performance and high security. It helps reduce loading time and provides faster content delivery by caching it on servers worldwide.

If you are not using a CDN, your site will take longer to load because the server in your country will have to wait for data from other countries before sending it to you, which can take up to an hour or more with some internet connections.

Outdated CMS

The CMS is also responsible for ensuring that the site’s content stays updated with recent changes in SEO guidelines, social media updates, and other important information. If a CMS becomes outdated, it can lead to loading issues and security risks for your site. It may also result in a drop in Google ranks and reduced traffic from social media sites such as Facebook and Twitter.

JavaScript Issues

The main issue with JavaScript is the loading speed. When the user is required to wait for the page to load before interacting with it, a problem arises. This causes frustration and can lead to users leaving your website for another that loads faster. 


  • Bloat is real, so audit your scripts to see what you need and remove what you don’t.
  • Asynchronous loading is a necessity.
  • A centralized platform like Segment or Google Tag Manager can help you stay on top of all your tools.

Unclean Code

Unclean code is a problem for programmers as it can slow down the loading of a webpage. The browser must spend more time parsing the code to understand it.

The best ways to avoid this are to use clean, semantic HTML and CSS markup. This means that you should not use IDs or classes without meaning, making it easier for browsers to parse through your code.

Too many HTTP Requests

Too many HTTP requests can often slow down web pages. This happens when the web page loads multiple images, scripts, and other resources that are not needed.

To speed up page loading time, developers should reduce the number of HTTP requests to as few as possible. This will not only improve the loading speed but also help increase the website’s conversion rate.

Incorporate browser caching

Caching stores files, web pages, and other content locally on a device so they can be accessed quickly later without an internet connection. When you visit a website, your browser downloads some information from that site and stores it in the cache on your computer so it will be available the next time you visit it.

The more frequently you visit a site, the more often these files are updated in the cache and the faster it loads. Caching is also important because it reduces the load on servers by only requesting updated content when necessary.

Excessiveness of Traffic

Excessive traffic is caused by a large number of visits to a website. Websites must have a good loading speed to ensure visitors stay on your website. For websites, having high traffic and low loading speeds will cause the site to crash or become completely unresponsive.

Unsatisfactory server performance

Server performance is a key factor in the success of any website. The loading speed of your website affects the conversion rate and, thus, your revenue. It’s a common misconception that faster servers mean higher costs. With the right hosting provider, you can have both high-quality servers at an affordable price.

Not using gZIP compression.

Compressing content can decrease a webpage’s loading time, which is why web developers often use gZIP compression. However, many websites need to start using this technique because they think it will make their site look less professional. 

The use of gZIP compression tools is essential for improving the performance of websites. There are many different types, and you should explore them to find the one which best suits your needs.

Too many Ads

Ads are a necessary evil for many websites and apps. They provide the revenue for the site or app and allow it to be accessible to the user. However, too many ads can slow down your loading speed substantially.

Ads can affect your loading speed by slowing down the processing of data on your device because it needs to process all of the data that is being downloaded from these ads when they are opened.

The simplest method to avoid this issue is to use an ad blocker to hide these adverts and prevent them from slowing down your connection or processing rates.

Images are unoptimized

Images are unoptimized because they are not compressed and take up a lot of space on the server. The more photos you have, the slower your loading speed will be.

Images can be used for various purposes, but they are often used for decoration, branding, and content. Optimizing images for the web is important, so they don’t slow down your site and deter your visitors from staying on it.

The first step is to compress the image to minimize file size and make the image simpler to load and show in the browser.

Extra themes, plugins, and comments

Themes are often one of the first things people change about their website. It’s not only about how it looks but also how it works. Many themes will improve your site’s loading speed without changing its look or feel.

Plugin comments are often overlooked as an area to optimize, but they can make a big difference in your site’s loading speed. If you have some plugins installed on your site, ensure they’re only doing what they need to do and nothing more.
