What is Gutenberg development?
Gutenberg development is the practice of building WordPress sites block-first — with custom blocks, block patterns, theme.json tokens, and full-site editing. The block editor done deliberately gives marketing a design tool that stays inside the design system rather than fighting it.
Why Gutenberg, deliberately
Gutenberg is the future of WordPress. Most agencies still treat it as the back-up plan.
Gutenberg is no longer the editor most agencies tolerate to deliver page-builder work — it's the platform WordPress is being built around. Block-based themes, full-site editing, theme.json, and the block editor have matured. We build Gutenberg-first when the brand wants editor flexibility without page-builder bloat, and when the in-house team wants a tool they don't need to be retrained on every six months.
What we hear most
When teams move to Gutenberg with us.
Editor is a wall of plain fields
Classic editor + ACF gives a content team rows of inputs that don't reflect what the page will look like. Editing requires Preview-Save-Reload purgatory.
Page builder bloat
Elementor or Divi loading 800KB sitewide. Editor exposes too many controls. Marketing drifts from the design system every release.
Custom blocks needed
A pricing block, a quote-request module, an interactive comparison — all live in the design system but no one wants to wedge them into the existing builder.
Block patterns missing
Marketing rebuilds the same hero, the same CTA strip, the same testimonial section every time. Patterns would save hours per page.
Full-site editing on the table
Brand wants the in-house team to edit headers, footers, and templates without filing a ticket. FSE is the answer when the design system is disciplined.
Theme.json governance
Type, colour, spacing tokens drift between PHP, CSS, and editor. Theme.json centralizes them — but only if it's set up properly.

Performance & SEO

Process
How this service runs end to end
The same six-step shape we use across every Haxtiv project — adapted to the specifics of this scope.
01
Discover
Audit, intent, and the part nobody is saying out loud
We open with a working session — not a deck. We pull analytics, crawl the existing site, audit the brand, and interview the people closest to revenue. We surface the friction inside the team, not just the friction on the screen.
02
Define
Sitemap, story, and the metrics that actually matter
We define the audience journeys, the commercial pages we are willing to defend, the SEO architecture, and the measurable outcomes. You get a shape of the project that survives feedback because it was built on evidence.
03
Design
Editorial system, art-directed, never templated
Type, grid, motion, and tone built as a system. We design the hero, the long pages, the unloved corners, and the empty states. Every screen looks like it belongs to the same studio. Nothing is parked for later.
04
Build
Production code your team can keep
WordPress, Shopify, or page builder — we build clean, accessible, performant, and documented. Component-led, naming you'll recognize next year, and a changelog your in-house team can read.
05
Launch
Migration without losing rankings or sleep
Pre-launch crawl, redirect map, schema and metadata cutover, performance baseline, and a launch playbook. We run the deploy with you, not at you.
06
Grow
Care plan, CRO sprints, and quiet improvements
We stay involved. Monthly performance reports, security and core updates, and CRO sprints that compound. The site gets better the longer you keep us.

Numbers we earn, not numbers we round up.

In their words
Senior teams who chose us.
Haxtiv replatformed our marketing site without losing a single ranking. We saw organic leads up 38% inside the first quarter and the editorial team finally has a layout system they don't fight.

Headless WordPress redesign
Our previous Shopify build was a Frankenstein of apps. The Haxtiv team simplified the stack, rebuilt the PDP and CRO patterns, and our store is faster and more profitable than it has ever been.
