How to Speed Up Your WordPress Site (2025 Edition)

Tony HermanByTony Herman Reading Time: 7 minutes

If your WordPress site feels sluggish, you’re not alone. A slow-loading website can hurt SEO rankings, annoy users, and lower conversions. This comprehensive guide gives you everything you need to speed up your WordPress site, combining the latest data, plugin recommendations, and expert tips—including what worked in my own experience.

Why is my WordPress Site Slow on Mobile?

Mobile devices often use slower connections. Large images, bloated themes, and excessive scripts hurt performance. Use responsive images and avoid sliders or animations that can crash mobile browsers.

Why WordPress Site Speed Matters

According to a Google study, the probability of a visitor bouncing increases 32% when page load time goes from 1 to 3 seconds. In today’s AI-assisted world, users expect lightning-fast pages. Plus, Core Web Vitals and page experience are now official Google ranking factors.

1. Get a Baseline Speed Score

Start by testing your site on these tools:

Record your scores before optimizing, so you can measure improvement. Record both desktop and mobile scores. Google bases their index (search results) on the mobile PageSpeed score, so that one is more important. This makes sense because most people see the mobile version of a website – since phones are used much more than desktop, laptop, and tablet devices.

2. Choose Fast Hosting

Don’t cheap out here. Hosting is the foundation of your website’s speed. Shared hosting with hundreds of neighbors will drag you down. I recommend:

  • Hosting.com (A2 Hosting) (solid speed + security)
  • SiteGround (great performance, strong support)
  • WP Engine (premium managed hosting)

3. Use a Lightweight Theme

Some themes are bloated with code and scripts. Instead, pick a speed-optimized theme. A few good options:

  • Kadence Theme
  • GeneratePress
  • Astra

Avoid drag-and-drop builders unless necessary (like Divi or Elementor) as they can slow things down. I prefer Kadence because it extends WordPress’ native editor, Gutenberg. This makes it more lightweight, so that it loads more quickly.

4. Install the Right Plugins

Too many plugins slow down WordPress. Only use what you need—and make sure they’re actively maintained.

Here are plugins I recommend:

  • Comet Cache – Easy caching solution.
  • Fast Velocity Minify – Combines and minifies JS/CSS.
  • WP Hyper Speed – Boosts caching and performance.
  • WP Speed 404 – Handles broken links gracefully.
  • Heartbeat Control – Reduces server load.
  • Robin Image Optimizer – Compresses images automatically.

5. Optimize Your Images

Images are often the biggest speed killers.

6. Clean Up Your Database

Use a plugin like WP-Optimize or Advanced Database Cleaner to:

  • Remove post revisions
  • Clear trashed posts/comments
  • Delete transients

7. Minimize External Scripts

Limit third-party services like:

  • Google Fonts (host locally if possible)
  • YouTube embeds (use preview thumbnails)
  • Chat widgets, ad scripts, etc.

Each one adds HTTP requests and slows your page.

8. Use a CDN

Illustration of how a CDN works.

A Content Delivery Network (CDN) serves your content from servers closer to users. It essentially takes a copy of your website and puts it on servers all over the country and world. Once you update a page on your website, an action takes place to remove the older version of the page and use the newer one, keeping your website up to date on all these servers. It’s an automatic process.

Top CDN providers:

  • Cloudflare (free + paid tiers)
  • Bunny.net
  • StackPath

9. Defer JavaScript and Inline Critical CSS

This means putting all your scripts (code) later on as the page loads so that people start to see a page load more quickly instead of seeing nothing.

  • Enable defer and async on JS files (Fast Velocity Minify can help)
  • Inline critical CSS so the page renders faster

10. Consider AMP (Optional)

For ultra-fast mobile speed, you can enable AMP (Accelerated Mobile Pages). Google offers a free AMP plugin, but it changes how your site looks—so test carefully.

Additional Tips

  • Monitor Site Speed: Use Google PageSpeed Insights and GTmetrix.
  • Preload Important Assets: Fonts and hero images should load early.
  • Limit External Scripts: Too many embeds (like YouTube or social widgets) will slow things down.
  • Clean Your Database: Use plugins like WP-Optimize or Advanced Database Cleaner to remove post revisions, spam comments, and more.

BONUS: My Starter .htaccess File

This code includes two important parts to increase your WordPress site’s speed. I don’t see anyone else offering this in their articles about increasing WordPress page load times.

  1. Get on the latest version of PHP. If you’re not on PHP 8 yet, where have you been? There are huge reductions in time when you do that. Get on the latest version. You may have to do some testing to make sure your website and all plugins are compatible with the latest version of PHP.
  2. Enable browser caching. Use the code below in your .htaccess file to enable it:
# Speed Optimization START
<ifModule mod_headers.c>
Header set Connection keep-alive
</ifModule>
# Speed Optimization END

# Compression START
<IfModule mod_deflate.c>
  # Compress HTML, CSS, JavaScript, Text, XML and fonts
