winno review (2026): Hiring a Swiss GEO agency, and how to check its work

winno is not a tool. winno GmbH, based in Männedorf in the canton of Zurich, is an agency that builds websites in Webflow and Shopify, runs SEO and offers GEO for Swiss SMEs. It writes in German for German-speaking Switzerland and the wider DACH region. The founders are Fábio Lichtler and Philipp Gomez. The brand dates from 2020 and the GmbH from 2023.

So this review asks a service buyer's questions, including how you keep an independent view of whether the work paid off. We read winno.ch, the GEO agency page, the agency comparison page, the about page, the grounding page and llms.txt on 20 October 2026.

What you get

winno builds GEO on top of existing SEO instead of selling it as a separate trick. The work, as described on its GEO page, runs in five steps:

A free visibility analysis before any contract.
A workshop that fixes the prompt set, phrased the way Swiss customers ask, and keeps it stable so monthly numbers stay comparable.
One-off technical work: Schema.org markup, llms.txt, and crawler access for GPTBot, ClaudeBot, PerplexityBot and Google-Extended.
Ongoing content passages with figures and sources added to pages that already rank, plus entity work and external mentions on directories and trade portals.
Monthly monitoring per AI system.

winno expects first movement after 6 to 10 weeks and a stable picture after about four months. Without an SEO base, it starts there.

There are two free ways in: an SEO check reviewed with you in a video call (with an AI-answer spot check on request), and a GEO visibility test of 25 customer questions on four AI systems, delivered within 3 working days.

How it measures

This is where winno is more open than most agencies. It names its tool: measurement runs with Finseo on the fixed prompt set across ChatGPT, Perplexity, Gemini and Google AI Overviews. The monthly report covers mention rate, citation rate, share of voice, competitor mentions and a source list per AI system, plus Search Console and Matomo data.

It also publishes its own numbers for winno.ch: 37 customer questions and 3,262 evaluated answers from 9 September to 8 October 2026, with overall visibility of 7.3% and no Gemini data for that period. It labels this clearly as its own measurement, not a client result.

One gap to note: winno optimizes for six AI systems but reports on four. Claude and Copilot are not in the measured metrics.

Price signals

There is no rate card. GEO starts with a fixed-price audit that tests your brand against 100 to 300 customer questions, and the price is named only in the quote. The GEO and comparison pages say SEO and GEO together cost more than CHF 10,000 over the first 6 to 12 months. llms.txt is more specific: SEO retainers from CHF 3,000 a month, and web design projects at CHF 10,000 to 30,000.

Those two framings do not quite match. CHF 3,000 a month for SEO alone would pass CHF 10,000 within four months. Ask for a line-item quote that separates the audit, the GEO retainer and any SEO work.

The +575% claim

The homepage shows a +575% organic traffic graphic. The about page cites average uplifts of +285% traffic and +340% qualified inquiries. None of these names a client, a period or a method. Treat them as marketing, not as a result you can expect.

The named references (Auto Group Schweiz AG, CPFirst Bar & Statthotel and SDRsofGermany) are more useful. Ask for a reference call and that engagement's Finseo report.

winno's comparison page of GEO agencies and tools (dated 9 October 2026) has a useful ten-question checklist, but its tool prices come from an agency that sells against those tools. Check figures on the vendor's own page.

What to ask before you sign

What does the audit cost, and what does the retainer cost after it?
Which prompts are in the fixed set, and do I get the raw answers or only the summary?
Why are Claude and Copilot optimized for but not measured?
Who owns the Finseo workspace if we part ways?
Can you show a client report from a named reference?

To its credit, winno states its own limits: nobody can guarantee a ChatGPT recommendation, and it lists cases where it is the wrong choice. It works in German only and says Romandie and Ticino content needs other help.

Why keep independent measurement

When an agency does the work and reports on it with a tool it picked, you have no second opinion. That applies to any agency, not only winno. Run your own measurement alongside theirs.

Promptwatch is built for this. Country-level tracking is on every plan, so you can track your own prompts for Switzerland. Citation analytics shows which pages, domains, Reddit threads and YouTube videos AI cites, so you can check that the external mentions winno lands are actually picked up. Agent Analytics, from Professional, logs whether GPTBot, ClaudeBot and PerplexityBot fetch the pages winno rewrote, and flags crawl errors after the technical work. Visitor analytics ties AI-referred sessions to conversions, which is the number a +575% graphic should be replaced with.

Essential at $95 a month gives you 50 prompts across all tracked LLMs with daily refresh, Claude and Copilot included. Professional at $245 adds crawler logs and 150 prompts. To run GEO in-house instead of hiring an agency, Content Agents plan, write and publish pages to Webflow, Framer or WordPress through a review inbox.

Verdict

winno is a credible choice for a German-speaking Swiss SME that wants website, SEO and GEO from one team, and it is more transparent than most about method and limits. Budget is the hurdle: no rate card and over CHF 10,000 in year one. Whoever does your GEO work, keep your own Promptwatch workspace running so you can see what moved, what was crawled and what converted.
