Wondering, “Why is my website slow?” Get answers with this rundown of what causes slow-loading websites (and how to fix them). With this walkthrough, you can learn how to optimize your site’s speed to deliver a better user experience and improve your site’s search engine optimization (SEO).
10 reasons (and fixes) for slow-loading websites
Some of the most common reasons for slow-loading websites include the following:
Some common fixes for this issue include:
- Using asynchronous loading
With cascading stylesheets (CSS), you bring character to your website. However, that character can backfire and create a slow-loading website that takes forever to load (or what feels like forever). This decreased load speed happens when there are unoptimized CSS files or multiple CSS requests.
Some common fixes for this problem include:
- Minify CSS files
- Combine CSS files
- Eliminate unnecessary CSS rules
- Use media queries to load stylesheets based on the device
Your website’s server can also slow down its loading speeds. A slow server happens for several reasons, from insufficient hosting resources to server-side issues. Typically, businesses upgrade their plan or switch service providers to resolve this issue.
Here is the complete list of how websites solve this problem:
- Change hosting providers
- Use server-side caching
- Optimize database queries
- Get a Content Delivery Network (CDN)
4. Content Delivery Network
Your CDN can also create a website that loads slowly. A Content Delivery Network optimizes content delivery by using a server closest to a user’s location. However, CDNs are not immune to site and page speed issues. Your setup and your provider’s capabilities can lead to a poor-performing CDN.
Some potential fixes for this issue include:
- Choose a CDN provider with a broad network
- Enable HTTP/2 support
- Use GZip compression
- Check caching rules
5. Content management system
A content management system (CMS) like WordPress can also create slow-loading websites. This issue often results from the CMS themes and plugins that businesses use. Whether you use a third-party or in-house theme, you can create page speed issues.
The most effective fixes for this issue include:
- Download CMS updates regularly
- Remove unused plugins
- Use a caching plugin
- Pick lightweight or optimized CMS themes
Caching, which helps search engines and browsers access the latest stored version of your website, can also decrease page speed. This page speed decrease happens when something goes wrong with caching, like repeated resource requests, as caching should improve load times.
Some common fixes for caching errors include:
- Use a CDN with caching features
- Download an optimized caching plugin
- Enable browsing caching
- Set up server-side caching
7. Media files
From images to videos to GIFs, your website’s media files can slow down your site significantly. Fortunately, it’s easy to fix speed issues related to media files. However, these fixes can take time without the help of a developer.
The most common fixes for media files affecting page speed include:
- Compressing media files
- Resizing media files to a lower resolution
- Using the WebP image format
- Enabling lazy-loading for media beneath the fold
- Hosting videos on external platforms
8. Website scripts
The code that powers your website, especially if you’re not using a content management system, can also affect your page speed. From inline scripts to poorly written HTML code, you can create issues that slow down your website and hurt your user experience.
Some of the most effective fixes for website scripts include:
- Minimize inline scripts
- Relocate scripts to the bottom of the page
- Use asynchronous loading
- Optimize the HTML code for parsing
9. Website plugins
While plugins offer ease and convenience, they can also slow down your website. In some cases, plugins can introduce security risks that put your website, business, and customers at risk. That’s why it’s vital to vet plugins thoroughly before adding them to your site.
You can help prevent website plugins from affecting your speed with these tactics:
- Stick to reputable plugins
- Remove unused or unnecessary plugins
- Update plugins regularly
- Limit the number of plugins
10. Website traffic
Your site’s traffic can also slow your site down. This scenario happens when a site receives an unexpected amount of traffic, which strains the website’s server and decreases its response times, thus creating a slowed user experience.
Businesses can respond to this issue by choosing a more appropriate hosting plan.
