Visual page builders (Elementor, Divi, WPBakery) have become the most popular tools in recent years for quickly building websites. To designers or marketing specialists, they feel like magic: no need to learn programming, everything can be placed using drag and drop directly onto the screen. However, what looks convenient on the outside is most often a technical disaster on the inside. In this case study, we look at a real Latvian industrial equipment services company whose website was completely transformed from a heavy visual builder to clean WordPress code.
Initial Situation and Diagnostics
The company approached us with classic complaints: to eliminate performance issues, targeted website speed optimization was combined with a review of advertising: "We invest funds in advertising, but the number of inquiries is low. On mobile phones, the page opens slowly, and in search positions, we constantly lose to competitors who have significantly less content."
During the initial technical audit, the following metrics were identified:
- Total page weight: 5.8 MB for the homepage alone.
- DOM element count: 2,840 elements on a single page (Google recommended limit is under 800). Every simple heading or button was wrapped in 8 to 10 nested
<div>containers. - Network request count: 114 separate files (38 different CSS files and 29 JavaScript scripts that mutually blocked rendering).
- Mobile load time (LCP): 4.8 seconds on a real mobile 4G network.
- Google PageSpeed score on mobile: 29 out of 100 points (deep in the red zone).
"A visual builder creates the illusion that you are building a house, but in reality, you are building a house out of packaging cardboard boxes where each subsequent box is nested inside the previous one. The browser on a mobile phone has to open all 2,000 boxes to finally find a single sentence. When you remove this unnecessary layer and build a clean wood and concrete structure, the result is staggering."
Rebuilding Process - From 50 Plugins to Clean Architecture
Instead of trying to fix slow code with plugins, modern clean code website development allowed rebuilding the site from the ground up while preserving existing content and URL structure:
Stage 1: Code Cleanup. The visual builder was completely dismantled. Instead, a custom, lightweight WordPress child theme was developed using the native Gutenberg block system without any external block plugins.
Stage 2: Style and Script Consolidation. All 38 separate CSS files were replaced with a single compact, minified stylesheet (size only 32 KB). The volume of JavaScript code was reduced by 90%, leaving only what is strictly necessary for the mobile menu and interactive forms.
Stage 3: Image Conversion to WebP. All heavy JPEG and PNG images were converted to modern WebP formats with precise dimensions, eliminating the browser's need to scale large images.
Stage 4: Server FastCGI Micro-Caching. Direct FastCGI caching was installed on the Nginx server, serving static pages directly from RAM in less than 50 milliseconds without PHP processor load.
Before and After Metrics Comparison
| Technical Metric | BEFORE (Visual Builder) | AFTER (Clean WordPress Code) |
|---|---|---|
| Total Homepage Weight | 5.8 MB | 640 KB (-89%) |
| DOM Element Count | 2,840 elements | 420 elements (-85%) |
| Network Request Count | 114 requests | 18 requests (-84%) |
| Mobile Load Time (LCP) | 4.8 seconds | 0.8 seconds |
| Google PageSpeed (Mobile) | 29 / 100 (Red) | 98 / 100 (Green) |
Business Results After 90 Days
Before implementing such improvements, it is recommended to perform a technical and speed audit. Three months after introducing the new code, the following business results were observed:
- Drop in Mobile Bounce Rate: Users no longer abandoned the site while waiting for a blank screen.
- Growth in Google Ads Conversions: Because the landing page opened instantly, the ad quality score increased, lowering the cost per click.
- Rise in Organic Rankings: The Google search engine appreciated the outstanding Core Web Vitals metrics, resulting in increased top-ten keyword positions for the company without purchasing additional backlinks.
Frequently Asked Questions About Clean Code vs Builders
Why is the Core Web Vitals INP metric so poor on Elementor sites?
Elementor loads dozens of JavaScript libraries that block the browser's main thread. When a user taps the screen, the browser cannot react immediately because it is busy processing scripts.
A slight improvement can be achieved with aggressive caching and file minification, but fundamental DOM depth and redundant requests cannot be resolved without rewriting the code.
How do Gutenberg custom blocks provide easy content editing?
Gutenberg blocks are built specifically for your company's needs: the client can change texts, images, and prices in a visually convenient environment, while the design grid and clean code remain safely protected.

Fixed budget. No hidden extra fees or forced services.In 2026, loading speed must fit within the Doherty 400ms threshold, where clean code and server-side caching fully outperform bloated plugins. Learn more in our Website Speed Optimization guide.
Visual page builders (Elementor, Divi) promise fast design creation, but their price is a massive DOM element tree, unnecessary megabytes of unused code, and critically poor Core Web Vitals on mobile devices. In a real client case study, rewriting into clean code reduced page weight from 4.8 MB to 380 KB while doubling mobile conversions.
