From SEO to GEO: the online search revolution

Online search has never stopped evolving

The way professionals and consumers find information online has gone through several major revolutions in three decades. Each transition has reshuffled the cards of visibility. The current transition, from classic search engines to AI answer engines, is the deepest of all.

For Swiss companies, understanding this evolution is not an academic exercise. It is a strategic necessity. Those who understood Google in 2005 dominated their market for 15 years. Those who understand GEO today will gain the same advantage.

Timeline: 30 years of online search

1994-2000: The era of directories

Early internet users found websites via directories such as Yahoo! Directory, DMOZ or online Yellow Pages. The logic was editorial: humans manually classified sites by category.

To be visible, you simply had to submit your site to the directory and be accepted. Competition was low, the internet had only a few million pages. In Switzerland, the first corporate websites appeared without a real visibility strategy.

2000-2010: The Google and keyword era

Google's PageRank algorithm revolutionised search by ranking pages by algorithmic relevance. SEO (Search Engine Optimization) was born: optimising your site to appear in Google's first results.

The levers: keywords in titles, meta descriptions, backlinks, rich content. The first SEO specialists appeared. Google became the universal entry point to information. Swiss companies invested massively in organic and paid search marketing.

2010-2022: The era of advanced SEO

Google made its algorithms more complex (Panda, Penguin, BERT, MUM). SEO became a sophisticated discipline integrating loading speed, mobile experience, topical authority and E-E-A-T content (Experience, Expertise, Authoritativeness, Trustworthiness).

The global SEO market exceeded USD 80 billion. In Switzerland, SME SEO budgets ranged between CHF 2'000.– and CHF 8'000.– per month. Being on the first page of Google had become a vital business issue.

2023-2024: The AI Overviews disruption

Google launched AI Overviews (formerly SGE): AI-generated responses directly in search results. Users no longer needed to click on a link: the answer is synthesised at the top of the page.

First earthquake: click-through rates (CTRs) on organic results dropped sharply for queries covered by AI Overviews. Classic SEO loses effectiveness, even for perfectly optimised sites.

2025-2026: The era of AI engines

Perplexity, ChatGPT with web browsing, Claude, Gemini and Copilot become credible alternatives to Google for information research. These AI answer engines do not return a list of links: they provide a direct, conversational, synthetic answer.

GEO (Generative Engine Optimization) emerges as the discipline that optimises visibility in these new engines. A new paradigm is taking hold: it is no longer about being ranked, but about being cited, recommended and preferred by AI.

AI engine adoption: the key figures

The shift to AI answer engines is not a projection. It is measurable.

• 73% of senior executives use generative AI weekly for decision-making (McKinsey, 2025).
• 62% of professionals in Switzerland use an AI assistant at least once a week (Deloitte Digital Switzerland, 2025). This figure rises to 78% among senior executives and B2B decision-makers.
• A growing share of B2B searches now starts on an AI assistant rather than on Google.
• Perplexity has shown a sustained growth trajectory since 2023.
• ChatGPT has more than 200 million weekly active users (OpenAI, 2024), of which a significant share use it as a search engine.
• Google's AI Overviews cover a growing proportion of informational queries, reducing organic CTRs.

In French-speaking Switzerland, this adoption is particularly marked in B2B sectors: consulting, IT, financial services, legal and healthcare. Decision-makers no longer systematically go through Google to assess a provider. They ask ChatGPT or Perplexity directly.

The concrete impact on businesses

Google visibility is no longer enough

A company perfectly ranked on Google can be completely absent from AI responses. The reverse is also true: some brands with little Google visibility are regularly cited by LLMs thanks to a strong semantic presence and consistent structured data.

Concretely, this means that your first-page Google ranking no longer guarantees your full visibility. You can invest several thousand francs per month in SEO and remain invisible to the growing share of prospects searching via AI.

The buying journey has changed

The typical B2B buying journey in Switzerland in 2026:

1. Discovery: the decision-maker asks a question to ChatGPT or Perplexity ("Which AI consultancy in French-speaking Switzerland?")
2. Evaluation: they ask AI for a comparison, which cites 3 to 5 players
3. Validation: they check on Google and visit the recommended sites
4. Decision: they contact the companies cited by AI

If you do not appear at step 1, you do not exist in this journey. And this journey represents a growing share of customer acquisitions.

The cost of inaction

Every month without GEO optimisation is a month during which your competitors consolidate their position in AI responses. LLMs "learn" cumulatively: the more a source is cited consistently and frequently, the more it becomes a reference. The snowball effect plays against laggards.

SEO + GEO convergence: the winning strategy

SEO and GEO are not in opposition. They converge. An integrated strategy produces results superior to either discipline taken in isolation.

What SEO brings to GEO

• Domain authority: a high DA feeds the RAG systems of AI engines, which use the web as a source.
• Regular indexing: a site well crawled by Google is also better captured by LLM retrieval mechanisms.
• Quality content: the E-E-A-T fundamentals of SEO are directly transposable to GEO.

What GEO brings to SEO

• Structured data: JSON-LD markup optimised for GEO also improves Google rich snippets.
• Factual and structured content: the clear, self-sufficient paragraphs GEO requires improve user experience, an SEO ranking factor.
• Multi-source consensus: the strategy of presence on third-party sources strengthens the backlink profile.

The 4-step action plan

1. Audit: measure your current visibility on Google AND on AI engines. A GEO audit reveals what ChatGPT, Claude, Perplexity and Gemini say about your business.
2. Structure: implement JSON-LD structured data (Organization, Person, Service, FAQ) and optimise the semantics of your content.
3. Amplify: build a multi-source consensus through third-party publications, professional directories and high informational-value content.
4. Monitor: monthly track your GEO Score and your SEO ranking to adjust the strategy.

This integrated approach is exactly what we deploy at MCVA Consulting for Swiss companies.

Operational summary

• Online search has gone through five eras: directories, Google, advanced SEO, AI Overviews, AI engines.
• 62% of Swiss professionals already use an AI assistant every week (Deloitte Digital Switzerland, 2025).
• Your Google ranking no longer guarantees your visibility. AI engines cite according to their own criteria.
• The optimal strategy combines SEO and GEO: the two reinforce each other.
• Companies that act now build a lasting competitive advantage. A SEO consultant specialising in French-speaking Switzerland can support you in this transition.

FAQ

Is SEO dead?

No. SEO is not dead — it is just no longer enough on its own. Google remains the dominant search engine in Switzerland. Organic traffic via Google still represents the leading source of acquisition for most companies. What has changed is that SEO now covers a decreasing portion of the total visibility spectrum. With a growing share of B2B searches starting on an AI assistant and AI Overviews reducing organic CTRs, a strategy exclusively focused on SEO leaves a growing blind spot. SEO remains a pillar. GEO becomes the indispensable second pillar.

Should you abandon Google Ads in favour of GEO?

No. Google Ads and GEO serve different and complementary objectives. Google Ads generates immediate, measurable traffic, with directly traceable ROI. GEO builds organic visibility on AI engines, which influences the buying journey upstream of Google search. Strategic recommendation: maintain your Google Ads campaigns for volume and immediate conversion, and invest in parallel in GEO to capture prospects who start their research on AI. In the medium term, a strong GEO presence can reduce your dependence on paid ads by increasing your organic traffic from AI recommendations.

How do you measure visibility on AI engines?

AI visibility is measured across four dimensions: Presence (is your brand cited when sector-related questions are asked?), Accuracy (is the information cited correct?), Sentiment (is the tone positive, neutral or negative?) and Recommendation (does AI actively recommend you?). At MCVA Consulting, we aggregate these four dimensions into the GEO Score, a proprietary 100-point metric measured on 5 AI engines. There is not yet a universal equivalent of Google Search Console for AI engines, which makes a specialised audit all the more necessary to get a reliable measure.
