AI Share of Voice for Local Businesses: How to Measure If You Show Up in ChatGPT, Perplexity, and Gemini

Traditional share of voice means how often your brand shows up versus competitors in paid or organic search. AI share of voice is the same idea applied to AI-generated answers.

When someone types a question into ChatGPT or Perplexity, the AI produces a short list of recommendations. If you show up in 4 out of 10 relevant queries, your AI share of voice is 40%. If you never show up, it's zero.

That number is becoming one of the most important metrics for local businesses. Buyers who use AI assistants tend to trust the recommendations they get. If your name never appears, you don't exist to that buyer.

You don't need any tools to get a rough read on where you stand. Open ChatGPT and ask it a question your ideal customer would ask. Something like: 'What is the best cosmetic dentist in [your city]?' or 'Where should I go for a Botox treatment near [your neighborhood]?'

Do the same search on Perplexity and on Google's AI Overview. Write down whether your business shows up, and if it does, where you appear in the list.

Repeat this with five or six different query variations. By the end you'll have a rough sense of your visibility. It won't be precise, but it will tell you if you have a problem.

ChatGPT, Perplexity, and Gemini all pull from different underlying data sources and use different ranking logic. A business that shows up confidently on Perplexity might not appear at all on ChatGPT, and vice versa.

Perplexity tends to rely heavily on live web results and structured citations. ChatGPT pulls from its training data plus real-time web browsing when enabled. Gemini is tied closely to Google's own knowledge graph and local business data.

This means optimizing for one engine does not automatically improve your visibility on others. A real AI visibility strategy has to account for all of them.

Checking once is easy. Checking every week across three AI engines, for five to ten query variations, in a way that lets you spot trends over time, is a different story.

AI recommendation results are not static. They shift as the models update, as new content gets indexed, and as competitors make changes to their own presence. A business that shows up today might disappear next month.

Without consistent tracking you can't tell whether what you're doing is working. You just have a snapshot with no context.

OptimizeMyGEO runs your queries across ChatGPT, Perplexity, and Gemini on a weekly cadence. Every run logs whether you appeared, where you appeared, and what the AI said about you.

The dashboard shows your score per model, your score over time, and how you compare to the competitors we track alongside you. You can see the exact queries we're running and the raw AI output that generated each score.

When something changes, you see it immediately instead of finding out three months later when a competitor has taken your place in every answer.

There is no universal benchmark because it depends heavily on your market, your category, and how competitive your city is. A cosmetic dentist in a mid-size city might reasonably target 60 to 70% share of voice across the queries most relevant to their practice. A restaurant in a major city might be happy with 30%.

What matters more than the raw number is the trend and the gap between you and your top competitor. If you're at 20% and your main competitor is at 65%, that's the number to close.

The free audit at optimizemygeo.com will show you your baseline and give you a sense of what's realistic for your market.

The quickest way to understand where you stand is to run the audit. Enter your business name, category, and city. We query ChatGPT, Perplexity, and Gemini using the searches your customers are most likely to run, and show you whether you show up.

If you're invisible right now, that's useful information. It means there's room to improve and the businesses that start optimizing first tend to hold those positions as AI search grows.

The audit is free and takes about two minutes. Get yours at optimizemygeo.com.
