Starting Performance: Not Bad, But Not Great

Before optimization, our website was performing decently, but there was plenty of room to grow:

  • Mobile speed score: low 80s
  • Desktop score: around 85
  • LCP over 4 seconds
  • Unoptimized images and render-blocking CSS/JS

Our Website Speed Optimization Process

We tackled performance in layers — cleaning up scripts, optimizing images, adjusting styles, and improving loading behavior.

1. Defer and Minify Scripts

All non-critical JavaScript was deferred and compressed to reduce render delay and Total Blocking Time (TBT).

2. Optimize CSS Delivery

We removed unused CSS and delayed non-critical styles to streamline rendering and improve First Contentful Paint (FCP).

3. Use Modern Image Formats

We converted key images to modern formats like WebP and AVIF, drastically improving Largest Contentful Paint (LCP).

4. Lazy Load Offscreen Assets

By lazy loading media below the fold, we sped up initial visual load and reduced Speed Index time.

5. Set Dimensions for Visual Stability

Fixed width and height attributes were added to all major images, reducing layout shifts and improving CLS.

Additional Benefits of WordPress Speed Optimization

Optimizing your WordPress website goes beyond fast load times. It directly impacts your site’s ability to rank higher in search engines, reduce bounce rates, and retain visitors. A well-optimized site improves user experience by ensuring pages load quickly on both desktop and mobile devices.

Speed also influences how frequently your site is crawled by search engines like Google. A fast website allows bots to index more pages per crawl session — a critical factor in SEO success.

How We Improve PageSpeed Score

One of our goals was to improve PageSpeed score using performance-first design methods. From compressing images with next-gen formats to restructuring HTML, CSS, and JS hierarchies, every tweak is measured and strategic. We also review server settings, caching policies, and implement a robust CDN to ensure global consistency.

Why WordPress Performance Tips Matter

WordPress performance tips are crucial for site owners and developers. It’s not just about plugins — it’s about understanding how to streamline your theme, leverage lightweight builders, and use tools that minimize database bloat. When done right, your Core Web Vitals skyrocket, especially your Largest Contentful Paint (LCP) and First Input Delay (FID).

Running a GTmetrix Website Speed Test

We consistently run a GTmetrix website speed test to validate performance improvements. GTmetrix provides valuable insights into structure, load order, and bottlenecks. When used in tandem with Google PageSpeed Insights, it offers a complete view of real-world site performance across multiple devices and browsers.

Why Website Speed Optimization Matters

Site speed impacts everything — from SEO rankings and bounce rates to conversions and revenue. A slow site will push users (and Google) away. A fast one keeps everyone happy.

We recommend checking your site with Google PageSpeed Insights and learning from trusted resources like Web.dev’s Core Web Vitals guide.
