What is the difference between a traditional and headless CMS?

A traditional CMS tightly couples the editorial back-end to the front-end presentation layer. A headless CMS separates them: content is stored and managed in a structured back-end and delivered via APIs to any front-end — website, mobile app, digital signage, and so on. This gives you far greater flexibility, faster performance, and the freedom to adopt new channels without re-platforming.

What does your digital accessibility service cover?

We offer the full accessibility lifecycle: an audit of your existing digital platforms against WCAG 2.2 criteria, a prioritised remediation roadmap, hands-on implementation (code fixes, component redesigns, alt-text and semantic HTML), and a conformance statement for the European Accessibility Act (BFSG). We also advise teams on embedding accessible design practices so new features are built right from the start.

What does your SEO service include?

Our SEO offering covers the full stack: technical audits and fixes (Core Web Vitals, crawlability, structured data), keyword and topic strategy, on-page content optimisation, and authority-building through link acquisition. We embed SEO considerations into every website project from architecture onwards, so digital visibility is built in rather than bolted on.

What is Generative Engine Optimisation and why does it matter now?

GEO is the practice of optimising your digital visibility to be cited and recommended by AI-powered answer engines such as ChatGPT, Google Gemini, and Perplexity. As these tools increasingly shape buying behaviour — especially in B2B — your brand's authority and information quality in training-accessible channels becomes a meaningful source of discovery. We optimise entity coverage, topical authority, and content structure so that AI systems recognise and surface your brand.

What is Digital Presence Strategy Consulting?

This is our upstream consulting service that defines where your brand needs to be visible, how it should be perceived, and what investment is required across channels — before any development begins. We conduct a digital footprint audit, assess competitive positioning, prioritise channels (organic, AI, paid, social), define KPIs, and produce a phased roadmap that brings your website, SEO, GEO, and content into a coherent strategy.

What is Digital Visibility and how do you improve it?

Digital visibility is the degree to which your brand is found, recognised and trusted across all the channels your buyers use — search engines, AI answer engines, social platforms, industry publications and beyond. Improving it requires a coordinated approach: a technically sound website, SEO built into the architecture, GEO for AI engine presence, content that earns authority, and performance marketing that amplifies reach. At SUNZINET, we treat digital visibility as the measurable outcome of everything we build and optimise together.

What CMS technologies do you work with?

We are technology-agnostic and maintain certified partnerships across a wide stack: TYPO3 (Gold Partner), Storyblok, Contentful, HubSpot CMS, Directus, Salesforce Experience Cloud, and others. We recommend the right technology for your specific requirements — scale, team capabilities, integration needs — not the one we happen to sell the most of.

Where are you right now?

Recognise your challenge

Global-Site challenge

You're running websites across multiple markets, languages, or franchise locations — and the cracks are showing. Brand inconsistency, duplicated content work, and no single source of truth are creating hidden costs.

Solution:

Bring everything together with a unified platform that keeps your brand consistent, eliminates duplicated effort, and gives every market a single source of truth.
Legacy Platform Problem

Your current platform made sense when you chose it. Now it’s slow, fragile under load, and holding your team back. Every workaround adds more complexity — and you’re facing another rebuild sooner than you’d like.

Solution:
Rebuild on a future-ready architecture designed to scale with your business, handle tomorrow’s demands, and avoid another costly rebuild in just a few years.
The Digital ROI Gap

Your website exists but isn’t generating enough leads. Campaigns take too long to launch, and editors remain dependent on developers — creating friction across teams and slowing down growth.

Solution:

Transform your website into a measurable growth channel with a platform and strategy that empower teams. Track performance, accelerate campaign delivery, improve CRO, generate new leads, and clearly review business impact.

Our work speaks for itself

The new website is already delivering measurable added value

Working with SUNZINET has noticeably strengthened our digital focus. The decisive factor for me was that the team quickly understood our goals and translated them into a clear, future-proof solution. The new website supports our brand, provides guidance for our target groups and is already delivering measurable added value. We received reliable advice at management level and were able to rely on well-founded decisions at all times. A partnership that I would highly recommend.
