Why your WordPress site is slow (and what to do about it)
Your website is often the first impression you leave on a potential customer. But when a WordPress site is slow to load, that impression can quickly turn into frustration... and lost revenue.
In this article, I present the common causes of slowness on a WordPress site, as well as concrete solutions to improve its performance. Essential reading if you want to maximize your online impact.
🚩 Why your site's performance is crucial
A slow site has several negative consequences:
- A higher bounce rate - Visitors quickly leave a page that takes too long to load.
- Affected SEO positioning - Google penalizes slow sites in its search results.
- Lower conversion rate - Users are less inclined to buy or fill in a form on a site that seems unreliable or slow.
In short: a fast site inspires confidence and converts better. It's an investment, not a luxury.
🔍 The main causes of a slow WordPress site
1. Too many poorly coded plugins or extensions
Some sites accumulate extensions without considering their impact. Each plugin can add weight to the load.
Solution: Eliminate non-essential extensions, and give preference to those recognized for their efficiency and lightness. An analysis with a tool like Query Monitor can help you identify greedy plugins.
2. Non-optimized images
Images that are too large or in the wrong format can slow down your site considerably.
Solution: Compress your images with tools such as ShortPixel or ImagifyUse WebP format whenever possible. Also ensure that images are correctly sized for their intended use.
3. Low-performance hosting
Cheap shared hosting can drastically limit the resources available for your site.
Solution: Opt for quality hosting, ideally optimized for WordPress and using LiteSpeed for best performance, especially if you're running a site with WooCommerce or Elementor.
4. Cache misconfigured (or non-existent)
Without a caching system, your site treats each request as if it were the first, which slows down the whole process.
Solution: Activate a cache plugin like LiteSpeed Cache or WP Rocket and configure it to take full advantage of your server.
5. Too many JavaScript/CSS files loaded unnecessarily
Many themes and extensions load scripts everywhere, even when they're not needed.
Solution: Use tools such as Asset CleanUp or Perfmatters to disable unnecessary files on certain pages. This considerably reduces the number of requests.
