Why Next.js + SEO?
WordPress was modern in 2010. Next.js is modern in 2026. And SEO without solid technical foundations is wasted money. Here's what that means for you.
The page is already prepared before your browser asks. Visitors in Cologne never wait more than a second for first content — and Google rewards that with better rankings (Server Components, Edge Rendering).
Google sees your full page immediately — no waiting time. Clean heading structure, automatic sitemap, indexing prepared from day one (Server-Side Rendering, semantic HTML, Core Web Vitals).
ChatGPT and Perplexity don't quote random websites — they quote the ones they understand. An invisible info-sheet in the source code translates your content into machine language (JSON-LD, Schema.org, AI Overviews).
When someone in Bergisch Gladbach searches for “tenancy lawyer”, your firm should be on top — not one from Hamburg. Clean geo data and a Google Business link make the difference (LocalBusiness schema, Google Business Profile).
A website that installs on a phone like a real app — without the App Store / Play Store detour. Own home-screen icon, full-screen view, works in spotty signal too (Progressive Web App).
Next.js is built by Vercel and Meta and used by Nike, Notion, OpenAI and TikTok. Translation: you won't be stuck on dead technology in five years like many WordPress themes from 2018.
Four pillars for top rankings
SEO in 2026 isn't just “add some keywords”. It's a technical, editorial and structural craft. These four pillars come standard — every project.
I decide which pages Google sees — and which it shouldn't waste budget on. Protection against duplicate content, mobile-first structure, scores above 95 in Google's own measurement tool. Since the 2021 Page Experience Update this isn't a nice-to-have, it's the baseline (Core Web Vitals, sitemap, robots.txt, canonicals).
Clear heading levels so Google understands hierarchy. One search intent per page — no two pages competing for the same term. Content that machines understand and humans actually want to read (heading hierarchy, keyword map, internal linking).
When someone in Bonn searches for “tax consultant”, your firm should appear — not one in Hamburg. Name, address and phone identical everywhere (otherwise Google thinks you're two different companies). Google Business Profile linked too (LocalBusiness schema, NAP consistency, Google Business Profile).
ChatGPT, Perplexity and Google AI Overviews only cite sources they recognize as reliable. Questions are marked up in source code so the AI can quote them verbatim — the new SEO discipline of the next 24 months (JSON-LD, FAQPage schema, AI-Overview optimization).
Most agencies in Cologne run WordPress, route you through three account managers and bill every email. Not me.
| Kriterium | Indievisual (Freelancer) | Klassische Agentur |
|---|---|---|
| Point of contact | You speak directly with the person who builds. | Account manager → project lead → developer. |
| Tech stack | Modern stack (Next.js 16, React 19) — what Linear, Vercel and Notion run on. | Usually WordPress with 30 plugins that need regular updates. |
| Response time | Under 4 hours on weekdays — no hotline, no ticket system. | Response times per contract, often 2–5 business days. |
| Pricing | Fixed price up front. What's agreed stands — no surprise add-ons. | Hourly rate plus tracking, every change as a billable change request. |
| Editing after launch | You type what should change — AI adjusts the code. Self-editable. | Every text change costs an hour of fees plus admin overhead. |
| Code ownership | The full source code lives in your account — switch providers any time. | You can't leave the system without rebuilding the site. |
| Contract terms | Cancel monthly — no lock-in, no friction. | Often 12–24 months minimum term. |

Research of the queries your customers actually type. One clear search intent per URL. No keyword cannibalization.

My tech & SEO stack
Makes your site load in under a second and lets Google understand it immediately. Used by Nike, Notion and OpenAI.
Buttons, forms, transitions stay smooth — on a MacBook and on a three-year-old Android alike.
Errors surface while writing, not weeks after launch. Cuts the bug rate roughly in half compared to plain JavaScript.
Want to change a color later? It's one place, not two hundred.
Delivers from the Frankfurt edge node — your visitor in Bonn loads from 200 km away, not from the US. Makes Lighthouse 95+ realistic.
Inquiries land reliably in your inbox, not in spam. Auto-confirmation to the sender included.
Daily view of which queries you rank for, where traffic gets lost and which pages Google can't find. Mandatory for serious SEO.
Reveals which keywords your competitors in the Rhineland capture — and which gaps you can fill without crowding.
Shows month over month whether your site is rising or sinking in Cologne and surroundings. Makes SEO success measurable.
Tells Google and ChatGPT what the page is — practice, law firm or restaurant in Bergisch Gladbach. Prerequisite for AI search engines like Perplexity to cite you.
Measures how fast the site really arrives at the visitor — on a 5-year-old smartphone, not on my workstation. Score below 90 = we grab a coffee and fix it.
Warns immediately when a change breaks load time — before it goes live.
Progressive Web App
A PWA (Progressive Web App) is a website that installs on a phone like a real app — without the App Store or Play Store detour. One tap on “Add to Home Screen” is enough. No 30 % Apple commission, no week-long store review, no duplicate code for iOS and Android.

About
I've been building websites for over ten years — the last four almost exclusively with Next.js, with a clear SEO focus. Used to be agency-side, now solo: closer to the code, closer to the customers, further from slide decks.
My standard: I deliver sites that don't look like templates, rank in Google's top 3 and that you can maintain yourself without calling me.
Packages
All prices as “starting from”, because every project is different. Always included: PWA, training session, 30 days of support, full code ownership for you.
One page. To the point.
Multi-page site that ranks.
When the website is the product.
For sites that need to keep getting better.
