7 Common Causes of a Slow Website (and How to Speed It Up!)
A slow website can seriously impair user experience. We explain 7 common causes of slow loading website with tips on how to speed it up.
First impressions count when it comes to websites. But if you have a slow website, you might not even get a chance to introduce yourself. Mobile users are 123% more likely to click off a slow-loading website of ten seconds or more.
It does not matter if you have great content. Part of your SEO strategy also has to be how to speed up a website. Whether you have a slow WordPress site or another web hosting platform, a slow website has common causes.
If you are asking yourself, ‘why is my website slow?’, read on. Here are seven common reasons for a slow-loading website and what to do about them.
1. Unoptimised Images
Unoptimised images are one of the leading causes of a slow website. There are several reasons why your photos are loading slowly:
- They are too large
- In the wrong file format
- All images load at once
- No clear dimensions
- The cache does not store images
- Not optimised for all devices
Large images can take up bandwidth and increase your website’s size, which slows down the whole site. Other media files such as videos can also slow down your site. Unoptimised images also impact your SEO performance too.
How To Speed up a Website With Image Optimization
First, check which format your images are in and set image dimensions. For future images, upload into formats such as JPEG, which is a lighter format. You can also convert current images on your site with a reputable plugin.
You can also resize and compress images. You can compress and lose some quality or compress without losing any quality to your pictures. Image optimisation plugins can speed up the process.
You can use lazy load, so images only load when the user sees the photos. Be sure to check that your site is responsive, too, so images can load no matter the device.
2. Too Many Ads
Ads offer many benefits, especially for sites with high traffic. But they can also cause a slow-loading website. Ads can cause many HTTP requests, which means a slow or even unresponsive website.
How To Speed Up a Website With Ads
Do not overload your website with ads. Pick responsive ads to list and fewer media-heavy ads. You can also find ways to use time delay, so not all ads appear at one time.
3. Code Issues
It is an achievement to build a website, but code can have its issues. If you notice unclean code, such as white spaces or anything else that is unnecessary, it could be slowing your website as it needs more load time. Unless you have the resources to manage dense code, such as Google who has 2 billion lines, you need to clean it up.
How To Clean Up Code
Speed up your website by cleaning and minifying code. Minifying refers to removing unnecessary characters from your website code without damaging how your website works. If you do not feel comfortable doing this, many IT services offer this service.
You can also try to keep to one CSS stylesheet instead of many.
4. Multiple HTTP Requests
How To Speed Up Your Website
Also, check how many external scripts you use, such as social feed plugins. Third-party and external scripts can also send unnecessary HTTP requests. Get rid of any you do not need or are willing to sacrifice.
5. No Content Delivery Service (CDN)
A CDN is a network of servers that are in different parts of the world. They work together to deliver internet content faster. The network caches content from the website, and the server closest to the person’s location will send the cached website content.
Use a CDN Network
Consider using a CDN network if you are not happy with your website loading speeds. CDN reduces the round-trip time and can improve website speed. If most of your traffic is local, it may not be worth it, but for international traffic, it can help.
6. No Caching Techniques
A cache is a temporary storage zone that helps load site information faster. Caching is the process of storing content you regularly visit, which increases how quickly the server can retrieve the data. If you are not using caching, it could be contributing to your slow-loading website.
How To Improve Caching
CDN can help cache your website. However, you can also start caching your website in other ways, such as browser and server caching. You can cache everything from HTTP to images.
