Only 16% of website visitors are willing to wait more than three seconds for your website to load. If your website is loading in four, five or even six seconds, you might be thinking, “What’s the big deal?”

Well, imagine your website as if it were Usain Bolt about to run in the Olympics final. Those few seconds are the difference between tasting gold and finishing last.

Your loading speed carries the same weight of importance when it comes to time on page, engagement and potential revenue for your brand.

That is why you want to make your WordPress site as fast as possible.

In this article, we’ll guide you through the common reasons why your WordPress site is slow. We’ll also share the best ways to improve and maintain your website, as well as the pros and cons of using WordPress for business.

How To Know If Your WordPress Website Is Too Slow

If you suspect that your WordPress site is slow to load, there are three ways to check its performance.

1. Use A Speed Testing Tool

The easiest way to analyze your website’s loading speed is to use a speed testing tool.

Some of the most common speed testing tools include:

  • Pingdom: a website performance testing tool that assesses loading times and identifies bottlenecks, helping you optimize sites for increased speed and performance.
  • GTmetrix: a comprehensive analysis of a website’s speed that provides actionable recommendations for improvement.
  • Page Speed Insights: Google’s tool for assessing website speed, providing insights and suggestions to optimize performance for a faster and smoother user experience.

Simply put your website’s URL into the search bar and the tool will dive into your site, pulling up an analysis and recommendations to improve your performance.

Most of these speed testing tools offer different pricing tiers. Depending on your specific business goals and budget, you want to align your goals with the pricing option that best matches your business.

2. Try An Application Performance Monitoring (APM) Tool

Application Performance Monitoring is the process of combining a number of tools to analyze site-wide performance, reliability and user experience (UX).

Using an APM tool will help you understand whether your WordPress site is slow. It will also provide more rounded information, as it will perform a deeper inspection of the composition of your website.

While the exact process of analysis depends on the specific APM tool you use, you can expect to receive support in at least five key areas:

  • Application Programming Interface monitoring
  • Application architecture
  • Service monitoring
  • Container monitoring
  • End-user experience monitoring

When combined, these features allow a company to not only track loading speeds, but also see a wide range of performance-related insights.

This gives a wider coverage of potential operating issues, helping you trace the root of a problem, such as coding errors or web hosting issues.

If you’re looking to use APM to increase the speed and improve the UX of your WordPress site, you should spend some time researching the best APM vendors for your unique requirements.

Some of the providers to consider are:

  • Dynatrace: advanced APM solutions, providing real-time insights for efficient issue resolution and improved user experience
  • DataDog: a comprehensive APM platform for monitoring, troubleshooting and optimizing application performance
  • Amazon CloudWatch: provides monitoring and observability for AWS resources, offering detailed insights into system metrics, logs and alarms

3. Test Your Themes & Plugins

You can also check if your WordPress site is slow by conducting speed tests with various combinations of themes and plugins enabled.

By running a speed test with various plugins enabled and consequently measuring speed after disabling certain plugins, you can identify which plugin is causing your website to lag.

Once you identify the culprit, simply remove, clean or update the plugins or themes installed within your website. Then, re-test your loading speed as needed.

What aspect of website optimization do you find most challenging for improving WordPress site speed?

9 Reasons Why You Might Have A Slow WordPress Site [+ Solutions]

If you have confirmed that your WordPress site is slow, here are nine possible causes and how to fix them.

Reason 1. Unreliable Web Hosting

Websites need reliable, high-performance servers to store their data and load pages quickly. Slow loading times, website downtimes and poor UX are all direct results of an unreliable web hosting provider that does not operate with the bandwidth, CPU and RAM needed to deal with high traffic volumes and spikes.

Solution:

When it comes to choosing a web host provider, you can refer to some of the leading web host providers on the market.

According to the number of clients and market share, the three leading hosting platforms are:

  • GoDaddy (9.29%): WordPress hosting plans from $8.99 to $20.99 a month
  • Google Cloud Platform (7.3%): Basic WordPress hosting plans from $13.17 a month, increasing depending on specific website requirements
  • Amazon Web Services (AWS) (4.48%): Amazon offers a pay-as-you-go pricing options, which means you pay for each individual service for as long as you use it

Reason 2. Too Many Plugins

WordPress is known for being a highly flexible and adaptable content management system (CMS), with its main advantage being the number of plugins it can utilize.

While these plugins can add features and functionalities to a website, they also come with their own set of code that needs to be executed each time the page loads. This code can negatively affect a page’s loading speed, especially if multiple plugins are running at once.

What’s more, some poorly coded plugins can add unnecessary strain on a server’s resources and further increase page loading time.

To ensure optimal performance, use only what is necessary and keep an eye out for plugins that may be slowing down your WordPress site.

Solution:

Be sure to scan the backend of your WordPress website, searching for old plugins that you haven’t deleted or active plugins that have little positive impact on your site.

In addition to keeping plugins updated to their latest versions, streamlining the number and quality of the plugins you use for your WordPress site will directly impact loading times and UX.

Reason 3. Failure To Use Caching

Caching is the process of storing a subset of data in a high-speed storage layer that is separate from the data’s original location. This allows future requests for this data to be received more efficiently, meaning shorter loading times and faster website speeds.

If you don’t utilize caching within a WordPress site, it can cause loading issues, as data and files are reloaded on every visit.

Solution:

Utilize caching, as it makes it more efficient to store files, consequently improving the website’s loading times and performance.

Here are three of the best-known cache plugins for WordPress (and their pricing):

Reason 4. Unoptimized Images

Not optimizing the images that are placed onto your WordPress website can cause major page speed problems down the line.

These images take up more space than necessary when they’re unoptimized, increasing page loading times.

In turn, users will leave your website without taking any action, negatively impacting your time-on-page analytics — all of which can harm your Google ranking.

Solution:

Utilize image optimization tools to optimize your images and improve factors that affect your Google ranking.

Some of the top tools (with prices) for image optimization include:

However, image optimization doesn’t just refer to heavy images and long loading times. For a seamless UX, your website shouldn’t render images larger than the user’s screen, regardless of whether they are visiting from a desktop or mobile.

An ideal image size for your WordPress depends on several factors, such as:

  • Web page layout
  • Context of your content
  • Image file format
  • Image optimization plugins

Reason 5. Failure To Use A Content Delivery Network (CDN)

A Content Delivery Network (CDN) is an important tool for optimizing WordPress website speed. Without it, all requests to view content on your website must be processed by your web server, which can cause page loading times to suffer as higher traffic comes in.

Solution:

Use CDN to load pages across multiple servers.

Reason 6. Excessive Ads Or Scripts

Both excessive advertising and advert placement can ruin credibility in terms of a website’s user interface (UI). Yet, more importantly, they are also a deciding factor in how Google views and ranks your WordPress site.  

Not only can an ad overload violate Google’s spam policies, but it can also cause an overcrowded landing page. This can negatively impact loading speeds and in turn, negatively impact UX. 

Note that since 2018, Google has claimed that UX is the core ranking factor it uses.  

Solution:

Limit the number of ads or scripts across your website.

Some pages may be able to store more ads and scripts without directly damaging the way the content appears on-screen. However, this does not make it possible to keep a high volume of ads, as they can still damage page speed, UX and eventually, Google rankings.

Reason 7. An Improperly Configured Database

Your database stores all the information needed to run your website, such as posts, pages, user accounts, comments and more.

If not set up correctly or maintained regularly, your site can become sluggish and unresponsive.

Improperly configured databases can also lead to errors when loading content from the server, which will further reduce speed.

Solution:

Free up space and optimize your database by removing spam comments, outdated content and redundant features.

Reason 8. Conflicting Themes & Plugins

When plugins and themes are not properly optimized or updated, they can cause compatibility issues.

Compatibility issues refer to the problems that may arise from outdated and unoptimized plugins that can result in slower page loading times.

Solution:

One way to avoid conflicting themes and plugins is to ignore the use of themes altogether, opting to develop a custom website design.

As a WordPress VIP Partner, we avoid the use of error-loaded themes, instead creating scalable and fully optimized custom websites tailored to your business goals and needs.

Reason 9. Large Video Or Audio Files

Videos and audio files are generally much larger than text or images, which means they take longer to load on the page.

However, avoiding videos and audio files altogether can damage user experience and engagement.

Solution:

WordPress lazy load video plugins can be an incredibly useful tool at cutting loading times by limiting file sizes.

Typically, you want to keep your WordPress file sizes to below 100KB, when possible. For larger files, sticking to the range of 100KB to 1MB would help prevent overloading and thus hindering the speed of your WordPress website.
