Why PageSpeed Matters

Let’s first understand why PageSpeed scores should be central to your WordPress optimization efforts:

Clearly, optimizing your WordPress site for blazing fast PageSpeed scores should be a top priority. Now let’s see how you can measure and improve the current performance.

Measuring Your Current PageSpeed

Google offers a free tool called PageSpeed Insights to evaluate your website’s loading performance on desktop and mobile.

Simply enter your URL, and PageSpeed Insights will analyze the page and provide speed metrics, including:

  • First Contentful Paint
  • Largest Contentful Paint
  • Total Blocking Time
  • Cumulative Layout Shift

Along with the overall PageSpeed score (out of 100), it highlights optimization opportunities and areas for improvement.

Other excellent options to measure PageSpeed include WebPageTest and browser dev tools. Use these freely to establish a speed benchmark for your site.

Now let’s explore proven strategies to optimize your WordPress site for faster PageSpeed…


Optimization Strategies

Image Optimization

Images often account for most of a web page’s size. Optimizing images is key for faster PageSpeed:

  • Resize and Compress: Scale down image dimensions and compress using tools like ShortPixel.
  • Choose Next-Gen Formats: Use WebP or AVIF instead of JPEG for better compression.
  • Lazy Load Images: Load only images visible on the page. Delay others until needed.
  • Enable CDNs: Distribute images globally using CDNs like Optimole and EWWW.

With the right tools and techniques, you can optimize images for PageSpeed without compromising on visual quality.


Implementing an effective caching strategy is crucial for WordPress speed optimization. Here are some tips:

  • Use Caching Plugins: Plugins like WP Rocket, WP Super Cache and LiteSpeed Cache can significantly improve caching.
  • Browser Cache Settings: Configure browsers to store cached pages through expiration times and validation checks.
  • CDN for Static Assets: Use CDNs for caching/serving static CSS, JS and image assets.

With caching, your pages load instantly instead of building each time from scratch. It’s a must-have for WordPress speed!

Minification and Combining Files

Minifying CSS, JavaScript and HTML code by removing whitespace, comments and unnecessary elements is a great way to reduce file sizes and optimize PageSpeed.

For even better performance, combine all scripts into one JS file and styles into one CSS file. Key plugins for this include:

You can achieve reductions of up to 80% in script/style sizes using minification and concatenation.

Choosing a Lightweight Theme

Your WordPress theme forms the foundation of the site. Choosing a lean, speed-optimized theme like GeneratePress, Astra or OceanWP is vital for achieving top PageSpeed.

Avoid bloated themes with excessive features. Optimize images, enable caching, and remove unused widgets/sections instead for the best experience.

Plugin Management

Too many plugins, especially those not actively maintained, can bloat your site and hurt PageSpeed.

Audit your plugins frequently and remove any unused, outdated or substandard options. Avoid plugin overlap or conflicts at all costs. Well-coded plugins from reputed developers, like those on, are always preferable.

Advanced Optimization Techniques

For more advanced users, additional options like server-side optimization, database caching, preloading etc. can further improve PageSpeed:

  • PHP 7.4 and HHVM: Use the latest PHP runtimes for faster processing. HHVM offers immense speed gains.
  • Database Optimization: Use database caching and query tuning plugins like WP-Optimize for faster data retrieval.
  • Preloading: Preload key CSS/JS assets to prioritize resource loading with plugins like Swift Performance.
  • HTTP/2: Leverage HTTP/2 capabilities for faster page loads and asset requests.

Maintaining High PageSpeed

Consistency is key when optimizing WordPress site speed. Follow these tips for maintaining high PageSpeed scores long-term:

  • Monitoring: Continuously monitor scores weekly/monthly using PageSpeed Insights and other tools.
  • Theme and Plugin Updates: Stay updated with the latest versions for performance improvements.
  • Backups: Take regular backups so you can quickly restore a faster version if needed.
  • Server Upgrades: Scale up your hosting plan or switch providers if site traffic demands faster servers.

With the right strategies, achieving 90+ scores on PageSpeed Insights is very much possible. You’ll notice tangible gains on site traffic, user engagement and revenue as well!
