PRESENSS is an AI Visibility Intelligence platform that measures and optimizes how a brand appears inside the answers of the 9 leading AI engines: ChatGPT, Gemini, Claude, Perplexity, Grok, Copilot, DeepSeek, AI Overviews and Meta AI. It produces the PRSNSS Score (0–100) and uses synthetic personas plus the Presence Agent to grow brand presence in AI.

What is GEO and how is it different from SEO?

GEO (Generative Engine Optimization) is the discipline of making a brand visible inside AI-generated answers — not in classic search result links. While SEO optimizes for ranking on Google or Bing, GEO optimizes for being mentioned, cited and recommended by ChatGPT, Gemini, Claude, Perplexity, Grok, Copilot, DeepSeek, AI Overviews and Meta AI.

How does PRESENSS measure AI visibility?

PRESENSS runs thousands of real queries across 9 AI engines using synthetic personas matched to your target audience. For every response it analyzes presence (mentioned or not), position (where the brand appears), sentiment, and context (recommended, compared, or merely listed). The result is the PRSNSS Score, on a 0–100 scale, segmented by engine, language, intent and persona.

What is the PRSNSS Score?

The PRSNSS Score is a 0–100 metric of a brand's visibility inside AI answers. It blends four components: Presence (35), Position (25), Sentiment (20) and Context (20), weighted by the market share of each AI engine (ChatGPT 18%, Gemini 16%, Claude and Perplexity 14%, Grok, Copilot and AI Overviews 10%, DeepSeek 8%).

Which AI engines does PRESENSS support?

PRESENSS supports the 9 leading AI engines: ChatGPT (OpenAI), Gemini (Google), Claude (Anthropic), Perplexity, Grok (xAI), Copilot (Microsoft), Google AI Overviews, DeepSeek and Meta AI (Llama).

Does PRESENSS track brand visibility inside Grok?

Yes. PRESENSS runs persona-driven queries against Grok (xAI) and scores presence, position, sentiment and context exactly as it does for ChatGPT or Gemini. Grok weighs 10% of the blended PRSNSS Score. Because Grok leans heavily on real-time social signals, PRESENSS also surfaces Reddit and X discussion opportunities as concrete Presence Agent actions for brands with low Grok visibility.

How do I get my brand cited by AI Overviews and Meta AI?

AI Overviews and Meta AI reward structured, citable content: FAQ and Product schema, clear factual statements near the top of the page, comparison tables, and mentions on third-party sources those engines already cite. PRESENSS identifies which external domains each engine cites for your category through citation tracking, then the Presence Agent generates the schema, content briefs and outreach needed to appear in them.

What are synthetic personas?

Synthetic personas are AI-generated user profiles — startup founder, enterprise buyer, technical user, marketing manager, local consumer — each with its own intent, language and search behavior. PRESENSS uses them to simulate how different real customers would query AI engines about your category.

What is the Presence Agent?

The Presence Agent is PRESENSS's autonomous optimization layer. It turns recommendations from the PRSNSS Score into concrete actions — content briefs, schema, citations, outreach — and either executes them on verified domains or delivers downloadable assets. It is included in the Business and Enterprise plans.

How much does PRESENSS cost?

PRESENSS has six tiers: Free (€0, 5 simulations/month, 2 AI engines), Starter (€49, 3 engines), Growth (€149, 5 engines), Pro (€299, 7 engines + citation tracking + API), Business (€499, all 9 engines + Presence Agent with 100 actions/month) and Enterprise (custom).

What is Generative Engine Optimization (GEO)?

GEO is the discipline of making your brand visible, accurately represented and recommended inside generative AI engines like ChatGPT, Gemini, Claude and Perplexity. Here is the complete definition.

A new layer of search has emerged

For 25 years, SEO meant one thing: rank on Google's blue links. In 2024 that started to change. Today, more than 1.5 billion people ask questions to ChatGPT, Gemini, Claude, Perplexity, Copilot, Grok, DeepSeek and Google's AI Overviews every month — and the answers they get rarely look like a list of links.

They look like synthesized recommendations. And if your brand is not in those recommendations, you are invisible to the fastest-growing discovery channel in human history.

That is what Generative Engine Optimization (GEO) is built to fix.

The official definition

> Generative Engine Optimization (GEO) is the discipline of optimizing how a brand, product or entity is represented across generative AI engines so that it is mentioned, cited and recommended in their answers.

While SEO optimizes for crawlers and ranking algorithms, GEO optimizes for how Large Language Models (LLMs) compress the web into a single answer.

How GEO is different from SEO

SEO ranks pages. GEO ranks brands inside answers.
SEO is measured by position 1–10. GEO is measured by mention rate, sentiment and recommendation share.
SEO rewards backlinks and keywords. GEO rewards structured data, citation-worthiness and consistent presence across high-authority sources.
SEO outputs a SERP. GEO outputs a paragraph that may never link to you.

The 4 pillars of GEO

1. Presence

Does the AI know your brand exists? If you ask Perplexity "best CRM for startups" and your brand is missing from the list, you have a presence problem.

2. Accuracy

When the AI mentions you, does it describe you correctly? Hallucinations are a brand-safety risk.

3. Sentiment

Is your brand described positively, neutrally or negatively in AI-generated answers?

4. Recommendation share

In comparative queries, what percentage of the time are you the recommended option vs your competitors?

Why GEO matters now

68% of brands are completely invisible in AI responses for their core category queries.
AI Overviews now appear in 47% of US searches, pushing organic clicks down 35%.
ChatGPT alone drives more referral traffic than X (Twitter) for B2B SaaS.

If you are not optimizing for GEO in 2026, you are betting your business on a search paradigm that is rapidly shrinking.

How to start with GEO today

1. Measure your baseline. Run a PRSNSS Score across 8 AI engines.

2. Audit your structured data. JSON-LD Organization, Product and FAQPage schemas are read directly by LLMs.

3. Build citation-worthy assets. Reddit threads, Wikipedia, G2, Capterra and high-DR blog posts are the sources LLMs trust most.

4. Monitor weekly. AI engines update fast. What works in March may be invisible in June.

The bottom line

GEO is not "SEO 2.0". It is a parallel discipline that sits on top of SEO. The brands that master it in 2026 will own the next decade of digital discovery.
