How to Migrate from Elementor to Gutenberg Blocks
Your agency built client sites with Elementor. Now you are dealing with slow page speeds, bloated DOM, plugin conflicts, and vendor lock-in. Migrating to Gutenberg blocks is not just possible — it is one of the smartest moves for long-term maintainability. Here is exactly how I do it.
Why Agencies Are Making the Switch
I have had an increasing number of agencies contacting me specifically for Elementor-to-Gutenberg conversions. The reasons are consistent:
Performance
Elementor loads 800KB+ of CSS and JS globally, even on pages that don't use it. After migration, I typically see page weight drop by 40-60% and Largest Contentful Paint (LCP) improve by 1-3 seconds.
Clean Output
Elementor generates deeply nested <div> structures — sometimes 8-10 levels of wrappers for a simple heading. Gutenberg outputs clean, semantic HTML that search engines and screen readers love.
No Lock-in
Deactivating Elementor leaves a mess of shortcodes and broken layouts. Gutenberg is part of WordPress core — your content stays clean and portable regardless of what plugins you add or remove.
Fewer Plugin Conflicts
Elementor's JS-heavy architecture frequently conflicts with caching plugins, CDNs, and other builders. Post-migration, the stack becomes simpler and more predictable.
The Migration Process (Step by Step)
This is not a "click a button and done" process. It is a structured rebuild that preserves the design while replacing the underlying technology. Here is my workflow:
Phase 1: Audit & Document
- Screenshot every page and template at desktop, tablet, and mobile breakpoints
- Map all Elementor widgets used to their Gutenberg block equivalents
- Identify custom Elementor widgets that need custom Gutenberg blocks or ACF blocks
- Document global styles: fonts, colors, spacing, custom CSS
- Export all content (text, images, links) into a structured document
Phase 2: Build the Gutenberg Foundation
- Create a clean block theme with
theme.jsondefining the design system (fonts, colors, spacing) - Build reusable block patterns for repeating layouts (hero sections, CTAs, testimonials)
- Create custom ACF blocks for any complex components not covered by core blocks
- Set up block locking and user permissions so clients cannot break the layout
Phase 3: Content Migration
- Rebuild each page using the new block patterns and custom blocks on staging
- Migrate content page by page — not automated, because automated tools produce messy output
- Preserve all URLs, meta data, and internal links to protect SEO
- Set up 301 redirects if any URL structures change
Phase 4: Testing & Launch
- Visual regression testing against the original screenshots
- Run Lighthouse and Core Web Vitals before and after, document the improvements
- Cross-browser and mobile testing
- Client training session on the new Gutenberg editing experience
- Deactivate and remove Elementor, clean up the database of Elementor metadata
Common Concerns (and My Answers)
"Won't my clients miss the drag-and-drop?"
In practice, most agency clients only edit text, swap images, and add blog posts. They rarely use Elementor's full drag-and-drop. With properly locked-down Gutenberg blocks and clear editing patterns, clients find it easier because there is less to accidentally break.
"Isn't Gutenberg limited for complex layouts?"
Not in 2026. Between the Group, Columns, Cover, and Row blocks — plus custom ACF blocks and reusable patterns — I can replicate any Elementor layout. The difference is the output is clean HTML, not nested div soup.
"How long does a migration take?"
A typical 10-15 page brochure site takes 2-3 weeks. Larger sites with WooCommerce or complex custom post types take 4-6 weeks. The investment pays for itself in reduced hosting costs, fewer plugin renewals, and significantly better Core Web Vitals.
