• LCP (Largest Contentful Paint) – Time to load main content
• FID (First Input Delay) – Time to interact with the site
• CLS (Cumulative Layout Shift) – Visual stability during load

Target Benchmarks:

🧪 3. How to Test Your Website Speed

Use these tools to measure your current performance:

• Google PageSpeed Insights – https://pagespeed.web.dev/
• GTMetrix – https://gtmetrix.com
• WebPageTest – Advanced waterfall view
• Lighthouse Report (in Chrome DevTools)

Check both mobile and desktop scores, as Google primarily ranks based on mobile-first indexing.

🛠️ 4. Techniques to Boost Website Speed

Here are practical strategies you can apply today:

✅ Use a Lightweight Theme

• Avoid bloated WordPress themes with lots of unused code
• Recommended themes: GeneratePress, Astra, Hello (for Elementor)

✅ Limit JavaScript and CSS

• Avoid using too many plugins and external scripts
• Defer loading of JS files
• Combine or minify CSS and JS files using plugins like WP Rocket or Autoptimize

✅ Enable Lazy Loading

Lazy load images, videos, and iframes so they load only when visible.

For WordPress, use plugins like:

• WP Rocket
• a3 Lazy Load
• Lazy Load by WP Rocket (free)

✅ Use Efficient Fonts

• Avoid multiple font families
• Host Google Fonts locally
• Use system fonts or variable fonts to reduce load time

🖼️ 5. Image Optimization Best Practices

Images often make up 60–70% of a page’s size. Optimize them with:

• WebP format – Smaller, modern alternative to JPG/PNG
• Compress images using TinyPNG, ShortPixel, or Imagify
• Resize images before uploading
• Add width and height attributes to prevent layout shift (CLS)

📉 6. Minification & Compression

Minify:

• Remove unnecessary characters from code (white spaces, comments)
• Tools: Autoptimize, WP Rocket, Cloudflare

Enable Gzip or Brotli Compression:

• Reduces file size of HTML, CSS, JS
• Use tools like Check GZIP Compression

🌐 7. Server & Hosting Optimization

Choose fast and reliable hosting.

Recommended Hosting for Speed:

• Cloudways (VPS-level performance)
• SiteGround (managed WordPress)
• Kinsta (Google Cloud infrastructure)
• Hostinger (budget-friendly)

Also:

• Use PHP 8.2+
• Limit shared hosting usage
• Enable object caching like Redis or Memcached

🌍 8. Use a Content Delivery Network (CDN)

A CDN distributes your content across servers globally, reducing load times.

Popular CDN Providers:

• Cloudflare (Free + Paid)
• BunnyCDN
• KeyCDN
• Amazon CloudFront

✅ Benefit: Users around the world access data from the nearest location.

🧹 9. Clean Up Unused Plugins & Database (WordPress Users)

Too many plugins slow down your site.

• Remove unnecessary or inactive plugins
• Avoid overlapping plugins (e.g., multiple SEO tools)
• Use tools like WP-Optimize or WP Sweep to clean:
  • Post revisions
  • Auto drafts
  • Transients
  • Unused tables

🔍 10. Tools to Monitor and Maintain Speed

Keep speed in check with these tools:

🔁 Ongoing Maintenance Tips
