Riad Hasan has optimized dozens of WordPress sites for clients worldwide. In this guide, he shares the exact techniques he uses to achieve sub-2-second load times and perfect Core Web Vitals scores.
Performance isn't just about speed — it impacts SEO, user experience, and conversions. Riad Hasan explains his systematic approach to WordPress optimization.
Why WordPress Performance Matters
Google's Core Web Vitals are now ranking factors. A slow WordPress site loses:
7% conversion rate for every 1-second delay
11% page views from frustrated visitors
16% customer satisfaction drop
"I've seen businesses double their leads just by fixing performance," Riad Hasan notes. "It's the highest-ROI improvement you can make."
Riad Hasan's WordPress Optimization Checklist
- Hosting Foundation
Before any code changes, Riad Hasan ensures the hosting is solid:
Factor Requirement
PHP Version 8.1 or higher
Memory Limit 256MB minimum
Object Cache Redis or Memcached
SSL HTTPS everywhere
Server Response Under 200ms
He recommends:
Cloudways — For managed hosting with Redis
Kinsta — Premium managed WordPress
DigitalOcean — For custom server setups
- Theme Optimization
Riad Hasan builds custom themes that are performance-first:
What he removes:
jQuery dependency (use vanilla JS)
Unnecessary CSS frameworks
Page builders (Divi, Elementor, WPBakery)
Bloated starter themes
What he adds:
Critical CSS inline
Deferred JavaScript loading
Optimized font loading (font-display: swap)
Lazy loading for images and iframes
// Riad Hasan's functions.php optimizations
function riad_optimize_scripts() {
// Remove jQuery migrate
wp_deregister_script('jquery-migrate');
// Defer all JS
add_filter('script_loader_tag', function($tag) {
return str_replace(' src', ' defer src', $tag);
});
}
add_action('wp_enqueue_scripts', 'riad_optimize_scripts');
- Plugin Audit
Riad Hasan follows a strict plugin philosophy:
Keep:
WooCommerce (if e-commerce)
Yoast SEO or Rank Math
WP Rocket or custom caching
Imagify or ShortPixel
Remove:
Contact form plugins (build custom)
Social sharing plugins (add manually)
Analytics plugins (use GTM)
Backup plugins (server-level backups)
Admin toolbar plugins
"Every plugin adds overhead. I count each one as a performance cost," Riad Hasan explains.
- Database Optimization
Riad Hasan's database cleanup routine:
-- Clean post revisions
DELETE FROM wp_posts WHERE post_type = 'revision';
-- Clean auto-drafts
DELETE FROM wp_posts WHERE post_status = 'auto-draft';
-- Clean trashed content
DELETE FROM wp_posts WHERE post_status = 'trash';
-- Clean orphaned postmeta
DELETE pm FROM wp_postmeta pm LEFT JOIN wp_posts p ON pm.post_id = p.ID WHERE p.ID IS NULL;
-- Clean transient options
DELETE FROM wp_options WHERE option_name LIKE 'transient%';
DELETE FROM wp_options WHERE option_name LIKE 'site_transient%';
He also:
Limits post revisions to 3
Sets auto-save interval to 60 seconds
Removes spam comments weekly
- Image Optimization
Riad Hasan's image workflow:
Step Tool Result
Compression ShortPixel/Imagify 70% size reduction
Format WebP 25% smaller than JPEG
Lazy Load Native + JS fallback Faster initial load
CDN Cloudflare/BunnyCDN Global delivery
He adds responsive images manually:
src="image-800.webp"
srcset="image-400.webp 400w, image-800.webp 800w, image-1200.webp 1200w"
sizes="(max-width: 600px) 100vw, 800px"
loading="lazy"
alt="Descriptive alt text"
/>
- Caching Strategy
Riad Hasan implements multi-layer caching:
Browser Caching (.htaccess):
ExpiresActive On
ExpiresByType image/webp "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/javascript "access plus 1 month"
ExpiresByType font/woff2 "access plus 1 year"
Object Caching (Redis):
Database query caching
Transient caching
WooCommerce session caching
Page Caching (WP Rocket or custom):
HTML page cache
CSS/JS minification
Delayed JavaScript execution
- WooCommerce Optimization
For e-commerce sites, Riad Hasan applies extra optimizations:
Cart Fragment Removal:
// Disable WooCommerce cart fragments
function riad_disable_cart_fragments() {
wp_dequeue_script('wc-cart-fragments');
}
add_action('wp_enqueue_scripts', 'riad_disable_cart_fragments');
Additional WooCommerce optimizations:
Disable scripts on non-shop pages
Limit related products to 4
Use product galleries efficiently
Implement AJAX cart sparingly
- Core Web Vitals Fixes
Riad Hasan's LCP optimization:
Preload critical images
Use server push for fonts
Optimize above-the-fold content
CLS prevention:
img {
aspect-ratio: attr(width) / attr(height);
height: auto;
}
FID improvement:
Break up long tasks
Use web workers for heavy JS
Minimize main thread work
Before and After: Riad Hasan's Results
Metric Before After
Load Time 5.2s 1.4s
LCP 4.8s 1.2s
FID 180ms 45ms
CLS 0.25 0.02
Page Size 3.2MB 450KB
Requests 85 22
"Every site I optimize follows this same systematic approach," Riad Hasan says. "The results are consistent."
