WordPress Performance Optimization — A Developer's Guide by Riad Hasan

Why WordPress Performance Matters

Google’s Core Web Vitals are now ranking factors. A slow WordPress site loses:

“I’ve seen businesses double their leads just by fixing performance,” Riad notes. “It’s the highest‑ROI improvement you can make.”

Riad Hasan’s WordPress Optimization Checklist

1. Hosting Foundation

Before any code changes, Riad ensures the hosting is solid.

4. Database Optimization

Riad’s cleanup routine (run via WP‑CLI or phpMyAdmin):

-- 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%';

Additional settings:

• Limit post revisions to 3
• Set auto‑save interval to 60 seconds
• Remove spam comments weekly

5. Image Optimization

Responsive image markup (example)

<!-- Replace with actual <img> tag -->
<img src="example.webp" alt="Descriptive alt text" width="800" height="600">

6. Caching Strategy

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

7. WooCommerce Optimization

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 tweaks

• Disable scripts on non‑shop pages
• Limit related products to 4
• Use product galleries efficiently
• Implement AJAX cart sparingly

8. Core Web Vitals Fixes

LCP (Largest Contentful Paint)

• Preload critical images
• Use server push for fonts
• Optimize above‑the‑fold content

CLS (Cumulative Layout Shift)

img {
    aspect-ratio: attr(width) / attr(height);
    height: auto;
}

FID (First Input Delay)

• Break up long tasks
• Use Web Workers for heavy JS
• Minimize main‑thread work
