Why Most Websites Are Slow and How to Fix Them

By Ted Politidis, Head of SEO at ergoseo.com

After working with WordPress, Linux servers, and performance optimization for more than 18 years, I can confidently say that page builders are not the real problem. In most cases, the page builder simply exposes weaknesses that already exist elsewhere in the website.

Page Builders Are Not the Real Problem

For example, I’ve worked on countless Elementor websites that initially scored around 57% in Google PageSpeed Insights. After optimizing the server, backend, database, and frontend, many of those same websites achieved scores as high as 97% while maintaining the same design and functionality. The transformation wasn’t achieved by replacing Elementor or installing another performance plugin. It came from understanding how WordPress actually works beneath the surface.

The Caching Plugin Trap

Why Stacking Plugins Makes Things Worse

One of the biggest mistakes website owners make is believing that every performance issue can be solved by installing another caching plugin. A slow website accumulates optimization plugins over the years until it resembles a collection of competing performance tools. WP Rocket, LiteSpeed Cache, Autoptimize, Asset CleanUp, Perfmatters, FlyingPress, image optimization plugins, database cleaners, and several CDN integrations all attempt to solve similar problems. Instead of improving speed, they frequently create conflicts, duplicate processes, increase server load, and make troubleshooting almost impossible.

Every Plugin Must Justify Its Existence

My philosophy has always been different. I use only a handful of carefully selected tools that each serve a specific purpose. If a problem can be solved at the server level, there is little reason to burden WordPress with another plugin that runs on every request.

Real Performance Starts Before the Browser

Real performance starts long before the page reaches the visitor’s browser. The web server, PHP configuration, MySQL database, object caching, file compression, HTTP headers, DNS response times, and even the operating system all influence how quickly a page is generated. When these components are properly configured, Elementor becomes far more efficient because it receives a healthy environment in which to operate.

The Database: Where Hidden Problems Live

The backend is where many hidden performance problems originate. Bloated databases filled with expired transients, fragmented tables, orphaned metadata, revision overload, and abandoned plugin data gradually slow down every database query. Poor indexing and inefficient SQL operations increase server response time before the browser even begins downloading images or CSS files. Optimizing the database often produces measurable improvements that no frontend optimization plugin can achieve.

Server and PHP Configuration

Server optimization is equally important. Incorrect PHP settings, insufficient memory allocation, outdated database configurations, excessive CPU usage, poor process management, and inefficient web server settings create bottlenecks that are invisible to most users. These issues cannot be solved by enabling another cache plugin. They require experience with Linux servers, Apache or LiteSpeed configuration, PHP tuning, and database optimization.

How to Optimize Elementor the Right Way

Identify the Bloat, Not the Builder

Elementor itself loads CSS, JavaScript, fonts, icons, and layout information. Most of this is perfectly reasonable for a modern page builder. The real issue arises when websites contain dozens of unnecessary widgets, third-party Elementor addons, multiple font families, oversized images, poorly written plugins, and scripts that load on every page whether they are needed or not. Performance declines because every additional request increases the workload for both the browser and the server.

I approach Elementor optimization by identifying unnecessary assets rather than removing useful functionality. Every stylesheet, JavaScript file, external request, and plugin is evaluated individually. If it contributes value, it stays. If it provides little benefit while consuming resources, it is removed or replaced with a lighter solution.

Images Are Still the Heaviest Offender

Images continue to be one of the largest contributors to slow websites. Uploading massive images directly from a camera or graphic design application wastes bandwidth and delays rendering. Proper resizing, modern image formats, intelligent compression, and lazy loading significantly reduce page weight without sacrificing visual quality. These improvements complement Elementor instead of fighting against it.

Core Web Vitals Changed the Rules

Core Web Vitals have also changed the way websites should be optimized. Google measures much more than loading time. Metrics such as Largest Contentful Paint, Interaction to Next Paint, Cumulative Layout Shift, and Time to First Byte all contribute to the overall experience. Improving these metrics requires a complete understanding of how the browser renders a page and how the server delivers content. Chasing a higher PageSpeed score without understanding these fundamentals often leads to optimizations that look impressive in reports but deliver little benefit to real visitors.

Why Frontend Tweaks Alone Will Never Be Enough

Many developers focus almost exclusively on frontend tweaks because they are easy to demonstrate. Minifying CSS, combining JavaScript, deferring scripts, or delaying execution certainly have their place, but they cannot compensate for an overloaded backend. A website with a slow database and poorly configured server will always struggle regardless of how aggressively the frontend is optimized. TTFB, for example, is a server issue, and ChatGPT won’t give you a viable solution because it lacks the technical page speed dataset to pull answers from.

My Optimization Process, Step by Step

My work begins behind the scenes. I optimize the operating system, configure the web server correctly, tune PHP, improve MySQL performance, reduce unnecessary database activity, eliminate inefficient plugins, and streamline WordPress itself. Only after the foundation is healthy do I move on to frontend improvements. The result is not simply a better PageSpeed Insights score but a website that feels genuinely responsive for every visitor.

Why Speed Is an SEO Investment, Not a Vanity Metric

One of the most rewarding aspects of this work is watching websites that were considered beyond repair suddenly become fast, stable, and enjoyable to use. Remember, user experience is a Google ranking metric, and the suite of Core Web Vitals was built primarily to measure UX. Faster pages and good UX reward owners with a reduced bounce rate, which feeds directly into improved SEO performance. Seeing a PageSpeed score rise from 57% to 97% is satisfying, but the real success lies in faster page generation, reduced server load, improved Core Web Vitals, lower bounce rates, and a noticeably smoother browsing experience.

Final Thoughts

Fast websites are not created by installing more optimization plugins. They are built through careful engineering, informed decisions, and a deep understanding of WordPress, Linux servers, databases, and web performance. When every layer of the stack is working efficiently, page builders perform exactly as they should. That is how I consistently transform underperforming websites into high-performing platforms that deliver excellent user experiences while achieving PageSpeed scores that many people assume are impossible.
