Over the past year, I’ve integrated Full Site Editing into multiple WordPress projects — from custom marketing sites to modular landing page systems for clients. FSE changes the workflow significantly, but with the right approach, it improves maintainability and hands control back to non-technical users.
Here are a few takeaways based on real use:
🔹 Block themes are non-negotiable
If you’re working with FSE, start with a proper block-based theme. Retrofitting classic themes creates unnecessary friction. I’ve had the best results using minimal starter themes or building from scratch with theme.json as the foundation.
🔹 Design systems matter more now
The Global Styles interface is useful, but unless you’ve mapped out a consistent design system, changes made by users can lead to visual drift. I usually define strict spacing, color, and typography rules in theme.json, which saves time later.
🔹 Patterns > templates for client sites
Clients rarely want to edit templates — they want flexibility in layout. I rely heavily on synced patterns, so clients can build consistent sections without touching structure.
🔹 Version control becomes trickier
With layout changes happening in the editor (saved to the database), versioning becomes messy. I handle this by exporting templates and patterns into the theme during development, then locking down critical parts before handoff.
🔹 Performance is still a manual concern
FSE doesn’t automatically lead to lean front-ends. You still need to audit block output, minimize unused styles, and keep assets clean. Don’t assume Gutenberg handles it all.
📌 I’m currently working with businesses that need custom WordPress block themes or want to transition from classic themes to an FSE-based stack.
If you’re planning that move or need someone who’s already been through the practical challenges of FSE — let’s talk.
