Two Very Different Philosophies

Elementor and GenerateBlocks are both WordPress page builders. The similarity largely ends there.

Elementor is built around maximum features. Drag-and-drop visual editing, 90+ widgets, a template library, a theme builder, a popup builder, form builder, and WooCommerce integration. It loads its full widget library on every page whether you use 5 widgets or 50.

GenerateBlocks is built around minimum footprint. Four core blocks (Container, Grid, Headline, Image), full design control, and almost no JavaScript on the front end. You build what you need. Nothing else loads.

This difference in philosophy shows up clearly in real-world performance data.

What the Data Shows

The Admin Bar tested Lighthouse performance scores on over 150 real agency-built WordPress sites in March 2025. The results:

Builder	Sites Tested	Median Lighthouse Score	Mean Score
GenerateBlocks	14	90	88
Elementor	30	66	67

That is a 24-point gap in median scores on real production sites. Not a controlled demo. Not a best-case scenario. Sites built by professional agencies that presumably have some optimization in place.

GenerateBlocks sites land in Google’s “Good” range (90+). Elementor sites land in “Needs Improvement” (50-89). The gap is structural, not incidental.

Why the Gap Exists

Elementor loads its complete widget library on every page as a single JavaScript bundle. A blog post with just a heading, body text, and an image still loads the full Elementor frontend JavaScript – including code for the carousel widget, the accordion widget, the counter widget, and every other widget you are not using.

WP Rocket’s controlled benchmark test recorded Elementor’s LCP (Largest Contentful Paint) at 5.4 seconds on a simple test page. Google’s “Good” LCP threshold is 2.5 seconds.

GenerateBlocks generates its layout via CSS classes. There is no JavaScript runtime on the front end for basic layouts. A page built with GenerateBlocks typically loads 30-60KB of total CSS and JavaScript from the builder itself. Elementor’s front-end bundle alone is 200-400KB.

Elementor’s Strengths (They Are Real)

This is not a one-sided case. Elementor has genuine advantages that explain why it has over 12 million active installs.

Easier to use for non-developers. The visual drag-and-drop interface is genuinely intuitive. Someone with no development background can build a decent-looking page without writing code.

More pre-built templates and widgets. The template library is extensive. For a first website or a quick landing page, the time savings are real.

Better for complex interactive elements. Pop-ups, form builders, sliding panels, and other interactive features are built in. GenerateBlocks requires additional plugins or custom code for these.

Larger ecosystem of third-party add-ons. If you need a specific feature, there is probably an Elementor add-on for it.

For a business site that needs to rank well in Google search and convert paid traffic efficiently, these advantages are meaningful but secondary to performance.

GenerateBlocks’ Strengths

Front-end performance. The 90 median Lighthouse score across 14 real-world sites speaks for itself.

Output is clean HTML and CSS. GenerateBlocks generates lean, semantic markup. No inline styles added to every element. No proprietary shortcodes that create dependency on the plugin being active.

Works with GeneratePress. GeneratePress is one of the fastest WordPress themes available. The combination of GeneratePress and GenerateBlocks consistently produces scores in the 85-100 range with standard optimization.

Easier to maintain long-term. Because there are fewer moving parts and no proprietary shortcodes baked into every page, a GenerateBlocks site is simpler to hand off, update, or rebuild in the future.

The Business Case for Performance

For a business site generating leads or sales, the performance gap has direct financial consequences.

Google Ads cost-per-click. Google’s Quality Score factors in landing page experience, which includes load speed. A low Quality Score means higher CPC. The difference between a Lighthouse score of 66 (Elementor median) and 90 (GenerateBlocks median) represents a meaningful Quality Score improvement on landing pages.

Organic rankings. Core Web Vitals – LCP, INP, and CLS – are confirmed Google ranking signals. A site consistently in “Needs Improvement” territory competes at a disadvantage against “Good” sites with equivalent content and backlinks.

Bounce rate. Google’s own research shows bounce probability increases 32% as page load time goes from 1 to 3 seconds. Elementor’s baseline LCP of 5.4 seconds puts the majority of mobile visitors in the abandonment zone before the page finishes loading.

Who Should Use Each

Elementor is the right choice if:

• You are building the site yourself with no developer support
• The design is complex with many interactive elements
• SEO and page speed are secondary priorities
• You need the extensive widget library and template ecosystem

GenerateBlocks is the right choice if:

• The site generates revenue and depends on Google rankings or paid search
• You have a developer building and maintaining the site
• Performance scores and Core Web Vitals are a priority
• You want a maintainable, lightweight codebase long-term

For most business sites that started on a ThemeForest theme with Elementor bundled and have since grown to where rankings and conversions matter, GenerateBlocks is the right direction for a rebuild.

The Migration Question

The most common concern: “I have years of content on Elementor. How hard is it to move?”

A professional rebuild is not a one-click migration. Each page is rebuilt in GenerateBlocks using the same content, the same structure, and the same URLs. The content itself – text, images, metadata – transfers. The layout is rebuilt from scratch in the lighter framework.

For a standard business site of 10-20 pages, this is a 5-15 business day project. The performance improvement on the other side is structural and permanent, not dependent on ongoing plugin updates or optimization plugin settings.
