What causes slow page load times in WordPress?

Decreasing page load time for your WordPress site matters now more than ever.

Page speed has been a ranking factor in Google's search algorithm since 2018. This means slow websites may rank lower in search results, making it harder for potential customers to find them.

Here are the most common culprits WordPress site owners need to challenge to improve their performance:

1. Large or Unoptimized Images

On average, images can account for anywhere from 50% to 80% of a webpage's total weight. That’s a significant portion that has a big impact on page load time, especially on the hardest Core Web Vital metric – Largest Contentful Paint (LCP). Ultimately, large unoptimized images can take longer to download and display, harming your site’s speed and user experience.

2. Lack of Caching

According to Google, a fast-loading website can improve conversion rates by up to 20% and reduce bounce rates to 32%. Caching reduces the amount of data that must be downloaded each time a page is loaded, leading to faster page load times and happier site visitors.

3. Unoptimized Databases

The database is the backbone of any WordPress site. A cluttered or unoptimized database can cause slow query processes, leading to slower performance. Unoptimized SQL queries can contribute for up to 60% of database performance issues, making it a critical aspect of website optimization.

4. External Scripts

External scripts, such as ads and social media widgets, can significantly slow down a WordPress site. Optimizing them and speeding up your site by only one second can lead to a 7% conversion boost.

5. Not Using a Content Delivery Network (CDN)

A content delivery network (CDN) is a must-have for any website that operates globally. CDNs distribute content across multiple servers, reducing the load on a single server. According to data from Cloudflare, using a CDN can result in a 60% reduction in page load times, making it an essential tool for website optimization.

6. Uncompressed and Minified Resources

A single uncompressed and unminified resource can add hundreds of milliseconds to your site’s loading time, so it’s crucial to ensure that all resources are optimized. Proper compression and minification can reduce the size of these file by up to 50%, leading to faster page load times and a better user experience.

7. Scripts that are not deferred

Deferring resources improves web performance by loading certain elements after the main elements have loaded. Lazy loading scripts is a powerful technique that significantly improves website speed, and many WordPress site owners choose.

Now that we’ve established what the most common culprits for slow page load times are, we can move on to the 6 best solutions you can find on WordPress. Plus 2 bonus tools at the end!

No matter your approach to site speed optimization – manually, with separate plugins, or an all-in-one solution – always remember:

  • First, identify the exact site speed issues you need to solve before introducing new WordPress tools to your tech stack
  • List your requirements and expectations from the plugins before you hit the Install button (e.g., specific features, update frequency, customer support availability, budget, etc.)
  • Remember that when it comes to plugins, less is more; downloading multiple plugins not only can bloat your site’s code but also cause security and compatibility issues.
