Presence Index: What It Is and How to Measure Your Visibility in AI

How do you know if your company appears when someone asks ChatGPT about your sector? How frequently does Perplexity mention you? What position does your business occupy in the AI's mind? To answer these questions with real data, GEOMOND developed the Presence Index: the first AI visibility metric in the Spanish-speaking market.

What Is the Presence Index?

The Presence Index is a score from 0 to 10 that reflects your company's real visibility in the main generative AI models: ChatGPT, Perplexity AI, Gemini, and Claude. It measures how frequently and relevantly these models mention your business when their users ask questions related to your sector, services, or geographic area.

It's not an estimate or a projection. The Presence Index is calculated by launching a set of real and representative questions to multiple AI models, analyzing their responses, and scoring your company's presence based on mention frequency, position in the response, and associated context.

The Presence Index was developed by the GEOMOND team in response to a real need: businesses needed an objective way to know whether they were on AI's radar and to measure the impact of their GEO actions over time. Since its introduction in 2024, it has become the central KPI of all the GEO projects we execute.

The Presence Index Scale

• 0–1: Total invisibility. AI is unaware of or ignores your company. No model mentions you when a user asks about your sector.
• 1.1–2.5: Minimal presence. You appear sporadically in very specific or niche responses, but you're not an established reference.
• 2.6–4.5: Emerging presence. AI starts to recognize you in some queries, but inconsistently. You have signals but not enough consolidated authority.
• 4.6–6.5: Established presence. You appear regularly in responses about your sector. AI considers you a relevant option, though not the main one.
• 6.6–8: Dominant presence. You're one of the main references AI mentions in your sector and geography. Your competitors follow you.
• 8.1–10: Absolute reference. AI positions you as the indisputable option in your category. You capture most mentions in high-value queries.

For context: most Spanish companies that have never worked on GEO have a Presence Index between 0 and 2. GEOMOND clients with 12 months of continuous work typically reach between 4 and 6.5 points, with the best cases reaching 7-8.

How Is the Presence Index Calculated?

The calculation combines several dimensions that are weighted according to their relative importance:

1. Mention frequency (40%): In what percentage of relevant queries does your company appear? If out of 50 representative questions in your sector, you appear in 15, your mention frequency is 30%.
2. Position in response (25%): Are you mentioned first, at the end, or in the context of "you might also consider..."? First-position mentions carry more weight than tail mentions.
3. Positive context (15%): Is the mention positive ("one of the best options"), neutral ("there's also X company"), or negative? The qualitative context of the mention is relevant.
4. Cross-model consistency (10%): Do ChatGPT and Perplexity mention you with the same frequency, or only one? Multi-model consistency is a sign of consolidated authority.
5. Coverage breadth (10%): Do you appear only in very specific queries or across the full range of questions in your sector? Coverage breadth reflects the depth of your presence in AI.

Benchmarks by Sector

Based on our analyses of Spanish companies, these are the average Presence Index values by sector for companies that have never worked on GEO:

• Clinics and health: 0.8–1.8 (majority at 0–0.5 if they don't have well-optimized Google My Business)
• Law firms: 0.5–1.5 (LLMs generalize a lot in legal)
• Consulting and B2B: 1–2 (if they have presence in sector media)
• Restaurants and retail: 1.2–2.5 (Google Reviews have some effect)
• Marketing and agencies: 1.5–3 (digital-native sector, higher baseline visibility)

Why Does the Presence Index Matter?

Because what isn't measured can't be improved. Before the Presence Index, businesses had no objective way to know whether they were on AI's radar. The metric enables strategic decisions based on real data:

• Establish a baseline: know exactly where you are today so you can measure progress
• Measure real impact: verify whether GEO actions are producing results
• Compare with competitors: understand who has an AI advantage in your sector and by how much
• Prioritize actions: identify which GEO pillars need more attention for the greatest impact
• Demonstrate ROI: present verifiable data to investors or executive management

The Evolution of Presence Index Over Time

The Presence Index is not static: it rises with well-executed work and can fall if the competition works more actively on their GEO. AI models are periodically updated with new data, which means visibility in AI requires continuous work, not a one-time intervention.

We've observed that clients with the highest rate of Presence Index improvement are those who work on all five pillars in parallel, publish new content regularly, and execute constant amplification actions. GEO is a marathon, not a sprint: the best results come after 6-12 months of continuous work.

How Long Does It Take to Improve the Presence Index?

GEOMOND clients improve their Presence Index an average of 0.5-1 points per month with continuous work. The first movements are detectable at 6-10 weeks. A 6-month cycle can take a business from 0 to 2.5-3 points, moving from total invisibility to established presence.

Factors that accelerate improvement are: having a solid content base to optimize, operating in a sector with low GEO competition, and applying all 5 pillars of GEO in parallel rather than sequentially.

How to Interpret Your Presence Index and What to Do With It

A low index (0-2) indicates that AI doesn't have enough structured information about your company and doesn't include you in its sector responses. The priority in this phase is the Entity pillar: Schema.org, NAP consistency, complete Google Business Profile. Without a solid entity foundation, the rest of the actions have limited impact.

A medium index (2.1-5) indicates that AI knows you but doesn't consider you a reference source. In this phase, the priority is the Content and Amplification pillars: create the best content pieces in the sector and multiply mentions in authoritative external sources. The goal is to move from "known" to "cited".

A high index (5.1-8) indicates consistent presence as a sector reference. The strategy in this phase is consolidation and expansion: more queries addressed, more geographies covered, more sector specifics where you can position yourself. In this phase it's also critical to monitor that model updates don't erode the position gained.

Frequently Asked Questions About the Presence Index

Is the Presence Index a GEOMOND metric or an industry standard? The Presence Index is a proprietary metric developed by GEOMOND. It's the first and most comprehensive generative AI visibility metric available in the Spanish-speaking market. The GEO industry is so new that there isn't yet a universal standard metric equivalent to Moz's DA or Ahrefs' AS for SEO.

How frequently does the Presence Index change? The Presence Index can change with each AI model update (which occur several times a year) and with the GEO actions you execute. We measure our clients' index every 4 weeks to detect trends and adjust strategy. An index that drops after a model update indicates that competition has gained ground or that the model has changed its selection criteria.

Can I calculate my Presence Index without GEOMOND? You can do a manual version: define 20-30 representative queries from your sector, launch them in ChatGPT, Perplexity, and Gemini, and record whether you appear and how. The appearance frequency weighted by mention quality gives you an estimate. The process is laborious but gives an idea of the magnitude of current visibility. GEOMOND automates and systematizes this process with greater precision and consistency.

How to Know Your Current Presence Index

GEOMOND offers a free Presence Index analysis for any company. Within 24-48 hours you'll receive your current score, an analysis of queries where you should appear but don't, and a comparison with the main competitors in your sector. No cost or commitment. It's the first step for any well-founded GEO strategy.

Can a competitor's Presence Index also be measured? Yes. The same query protocol we use to measure your Presence Index can be applied to estimate that of your main competitors. This allows building a comparative analysis of the state of GEO in your sector and understanding how much ground you need to gain (or how much you need to defend) to be the AI reference in your category.

Measuring your Presence Index is the first step of any serious GEO strategy. Without baseline data, there's no strategy: only intuitions. GEOMOND's free diagnosis provides you with your current Presence Index in 24-48 hours, with a breakdown by AI model and by sector query type, so you can make the decision to invest in GEO with real data and a clear baseline from which to measure progress.

The Presence Index is not a static number: it changes with each GEO action you execute and with each AI model update. Measuring it regularly (every 4 weeks is the recommended cadence) allows you to detect whether actions are working and adjust strategy in time. Without regular measurement, GEO is blind optimization.
