Why Page Builders Slow Down WordPress Website Performance

Introduction

Page builders like Elementor, Divi, WPBakery, and Beaver Builder make it easy to design WordPress websites without coding. However, while they provide convenience, they often come at the cost of WordPress website performance and speed. A slow website can negatively impact SEO rankings, user experience, and conversion rates.

While these tools are great for beginners, they come with trade-offs that many website owners overlook. Slow-loading pages frustrate visitors, increase bounce rates, and lower search engine visibility. If your business relies on online traffic and conversions, understanding the drawbacks of page builders is essential.

This article explains why page builders slow down WordPress websites and how to optimize performance if you choose to use one.

⚠️ Excessive Code & Bloat

Problem: Page builders generate bloated code that affects load speed.

• Every element added (buttons, sliders, forms) includes extra HTML, CSS, and JavaScript.
• Page builders often wrap content in multiple nested divs, increasing page size.
• Extra styling rules override WordPress’s default CSS, leading to excessive code processing.
• Unnecessary code execution slows down rendering and impacts user experience.

Solution:

• Use only the essential features of the page builder.
• Minimize the number of elements per page.
• Consider lightweight alternatives like GenerateBlocks or Kadence Blocks.
• Audit and remove unused widgets or modules to improve page efficiency.

🐌 Increased HTTP Requests

Problem: More elements = more HTTP requests.

• Page builders load multiple CSS and JavaScript files.
• Some load Google Fonts, FontAwesome icons, and animations separately.
• Additional files mean longer loading times for visitors, especially those on slower connections.
• Excess HTTP requests increase server load and impact performance on shared hosting.

Solution:

• Use a caching plugin to combine and minify scripts (e.g., WP Rocket, Autoptimize).
• Disable unnecessary page builder features.
• Load Google Fonts locally instead of externally.
• Consider using system fonts instead of third-party font libraries.

📉 Poor Core Web Vitals Performance

Problem:

Google measures Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS)—page builders often negatively affect all three.

• LCP Issues: Large, unoptimized page builder elements load slowly.
• FID Delays: Excess JavaScript slows interactivity.
• CLS Problems: Page builders load dynamic content late, causing layout shifts.
• Extra scripts and animations add to render-blocking elements.

Solution:

• Enable lazy loading for images and videos.
• Optimize above-the-fold content using critical CSS.
• Test site speed with Google PageSpeed Insights.
• Reduce dependency on animated or interactive page builder elements.

🔄 Dependency on Shortcodes & Inline CSS

Problem: Many page builders use shortcodes to render elements.

• Shortcodes are processed dynamically, increasing server load.
• Inline CSS adds unnecessary styling instead of using external stylesheets.
• Too many shortcodes cause conflicts with other WordPress plugins and themes.
• Overlapping styles increase DOM complexity, leading to slow rendering times.

Solution:

• Switch to theme-based layouts when possible.
• Consider a Gutenberg-based design for speed benefits.
• Use custom CSS instead of page builder styling.
• Limit the use of global shortcodes to essential components only.

🖥️ Server & Database Load

Problem:

• Some page builders store layouts in the database, slowing queries.
• Higher CPU and memory usage impact shared hosting environments.
• Excess database queries increase TTFB (Time to First Byte).
• Page builders often store revision histories, increasing database size.

Solution:

• Use a well-optimized hosting provider (e.g., Kinsta, WP Engine, SiteGround).
• Clean up the database regularly with WP-Optimize.
• Enable Object Caching to reduce database queries.
• Limit post revisions to prevent database bloat.

⚖️ Alternative Solutions: Lightweight Page Builders

If you must use a page builder, consider lighter options:

• Bricks Builder – Minimal bloat, highly customizable.
• Oxygen Builder – Designed for performance with clean code.
• GeneratePress + GenerateBlocks – Integrates well with native WordPress functionality.
• Kadence Blocks – Optimized for speed, works with Gutenberg.
• Breakdance Builder – Newer builder focused on performance-first design.

🚀 Best Practices to Optimize a Page Builder Website

If removing a page builder isn’t an option, follow these steps to improve performance:

✅ Optimize Images

• Use WebP format instead of PNG/JPEG.
• Compress images using ShortPixel or WP Smush.
• Enable lazy loading for offscreen images.

✅ Reduce Plugin Overload

• Disable unused page builder modules.
• Remove unnecessary WordPress plugins.
• Replace bloated plugins with lightweight alternatives.

✅ Leverage Caching & CDNs

• Enable browser caching and Gzip compression.
• Use Cloudflare or another CDN to serve static files faster.
• Implement server-level caching when possible.

✅ Minimize Render-Blocking Resources

• Load JavaScript asynchronously or defer loading.
• Inline critical CSS for faster rendering.
• Remove unused CSS and JavaScript files.

🚀 Final Thoughts

While page builders offer design flexibility, they can significantly slow down WordPress websites due to excess code, HTTP requests, and database queries. If performance is a priority, consider using Gutenberg, lightweight page builders, or custom-coded themes.

If you’re already using a page builder, optimizing images, reducing plugins, leveraging caching, and minimizing render-blocking elements can help speed up your site.
