🚀 What Makes a WordPress Site Fast? A Developer’s Checklist

A slow site doesn’t just frustrate users — it also hurts your SEO rankings, conversions, and credibility. Over the years, I’ve worked with clients who thought speed was all about installing a caching plugin. But real performance starts earlier — with architecture, development practices, and how you manage assets.

This is the checklist I personally follow to build fast WordPress sites that pass Core Web Vitals and perform well under real-world traffic.

1. 🧱 Use Lightweight Themes & Avoid Plugin Bloat

Speed starts with your foundation.

I always:

• Avoid multipurpose themes with 10 sliders and 30 demos
• Use lightweight themes like GeneratePress, Blocksy, or a custom-built base
• Audit every plugin — if it’s not needed, I remove it

👉 Rule of thumb: fewer plugins = fewer queries, scripts, and chances for conflict.

---

2. 📊 Optimize Database Queries (or Use Custom Tables)

Too many developers rely entirely on wp_postmeta and wp_options. That’s fine — until your site has 20,000 records.

I:

• Use custom tables when storing structured or repeatable data
• Optimize WP_Query with the right parameters (no_found_rows, fields => ids, etc.)
• Avoid autoloading unnecessary options

👉 A bloated wp_options table with too many autoloaded fields can drag down even simple pages.

---

3. ⚙️ Load Scripts Wisely (defer, async, conditionally)

Don’t load jQuery on every page. Don’t load your custom slider script when it’s not needed.

I:

• Enqueue scripts only when necessary (is_page() or is_single() conditions)
• Use defer and async where possible
• Minimize third-party embeds unless essential

👉 Less JS = faster TTI (Time to Interactive)

---

4. 🖼️ Image Optimization & Lazy Loading

I:

• Resize images before uploading (no need to use a 4000px photo on a 300px area)
• Use modern formats like WebP
• Add native lazy loading (loading="lazy" on <img> tags)

Bonus: I run assets through tools like TinyPNG or ShortPixel before they hit production.

---

5. 📦 Use Page Caching + Object Caching

While caching isn’t everything, it is essential.

I typically:

• Use LiteSpeed Cache (especially if hosted on LiteSpeed server)
• Enable object caching via Redis or Memcached for dynamic sites
• Set up server-level caching where possible (Cloudflare, hosting-level Varnish)

👉 Caching is the last 20% that makes your 80% work shine.

---

6. 🧼 Minify & Combine CSS/JS (Carefully)

I minify CSS and JS, but with caution — combining everything into one file doesn’t always help on modern HTTP/2 or HTTP/3 servers.

Instead:

• Use a smart build pipeline or a plugin like Autoptimize
• Minify only when assets are stable (no frequent changes)
• Exclude scripts that break with minification

---

7. 💡 Hosting Matters — Don’t Cheap Out

No amount of clean code can fix a $1/month shared hosting plan.

I recommend:

• Hostinger, Cloudways, or any VPS where you control server config
• Use object caching, PHP 8.x, and LiteSpeed or Nginx
• Don’t overpay for “WordPress-specific” features you don’t use

👉 Your site speed is only as good as your server response time.

---

🎯 Final Thoughts

Speed is more than a Lighthouse score — it’s about how the site feels to real users.

As a developer, I focus on writing lean code, minimizing server load, and ensuring assets are only loaded when they’re truly needed.
