Use it at https://aeometer.com/tools/ai-visibility-checker. ## How the checker works 1. **Describe your brand.** Brand name, what you sell, who buys it and up to five competitors. The checker writes 8 to 12 buyer prompts across five intents. 2. **Ask each engine.** Open each prompt in ChatGPT, Claude, Perplexity and Google, each in a new tab, and read what comes back. 3. **Mark what you see.** Mentioned, Not mentioned, Competitor only or No answer. Your mention rate and per-engine breakdown update as you go. ## Prompt templates The checker fills these templates from your inputs. They follow the same patterns AEOmeter uses for the starter prompts it suggests when you add a brand. None of them names your brand, because a question that names you mentions you by definition. Tokens: `{category}` is what you sell (for example "product analytics tool"), `{audience}` is who buys it (defaults to "a small team"), `{competitor1}` and `{competitor2}` are the first two competitors you list, `{problem}` is an optional problem phrased as a verb ("find out why users churn"). Templates are used in this order, up to 12 prompts. | Intent | Template | Used when | | --- | --- | --- | | Category discovery | What is the best {category}? | always | | Category discovery | Which {category} would you recommend for {audience}? | always | | Category discovery | What are the top {category} options right now? | always | | Comparison | Compare the most popular {category} options for {audience}. | always | | Comparison | {competitor1} vs {competitor2}: which is better for {audience}? | 2+ competitors | | Comparison | Is {competitor1} the best {category} for {audience}, or is there something better? | exactly 1 competitor | | Alternatives | What are the best alternatives to {competitor1}? | 1+ competitor | | Alternatives | What are the best alternatives to {competitor2}? | 2+ competitors | | Alternatives | What are some lesser-known {category} options worth trying? | no competitors given | | Problem-led | How can {audience} {problem}? | a problem is given | | Problem-led | What tools help {audience} {problem}? | a problem is given | | Use case | Which {category} is easiest to set up for {audience}? | always | | Use case | What is a good {category} for {audience} on a tight budget? | always | | Use case | Which {category} should {audience} switch to as they grow? | always | Example for a product analytics tool sold to seed-stage startups, with Mixpanel and PostHog as competitors: "What is the best product analytics tool?", "Mixpanel vs PostHog: which is better for seed-stage startups?", "What are the best alternatives to Mixpanel?". ## Asking each engine Ask each prompt in a fresh chat on every engine, so earlier conversations don't shape the answer. - **ChatGPT:** Opens a new chat in your ChatGPT account. - **Perplexity:** Runs the search right away. - **Claude:** Needs a Claude login. Start a new chat for each prompt. - **Google AI Overviews:** Look for the AI Overview above the results. Mark No answer if there is none. ## Marking each answer - **Mentioned:** The answer names your brand. - **Not mentioned:** You are not named, and neither is any competitor you listed. - **Competitor only:** A competitor you listed is named and you are not. - **No answer:** Error, refusal, login wall, or no AI Overview. Left out of the score. Mention rate = Mentioned ÷ (Mentioned + Not mentioned + Competitor only). No answer is left out of the denominator. With zero usable answers the rate is a dash, not 0%. Calculate it overall and per engine. ## How to read your results The checker uses the same mention rate AEOmeter calculates for tracked brands, with you doing the reading instead of the software. **Mention rate:** Answers that name your brand ÷ answers that came back. If ChatGPT names you in 3 of 8 answers, your ChatGPT mention rate is 38%. An engine with no usable answers shows a dash, not 0%. See the [methodology](https://aeometer.com/methodology) for how AEOmeter counts it. **No answer:** Errors, refusals, login walls and searches where Google showed no AI Overview. They say nothing about your visibility, so they are left out of the denominator. **Competitor only:** The most useful mark on the page. The AI recommended someone in your category and it wasn't you. Open that answer again and note which pages it cites. That is your reading list for this question. **Per-engine breakdown:** Each engine builds its answers differently, so a strong ChatGPT number and a weak Perplexity number is common. Start with the engine your buyers use most. ## What this score can't tell you - **It is one sample.** Ask the same prompt twice and you can get a different list of brands. A single check is a snapshot of one moment. - **Answers are personalized.** Signed-in accounts can use memory, past chats and location, so what you see can differ from what a buyer sees. - **The sample is small.** 12 prompts on 4 engines is 48 answers at most. A 10-point gap between two engines can be noise. - **You decide what counts.** AEOmeter counts a mention when an answer contains your brand name or one of its aliases as a whole word. Use the same rule here so your numbers compare. ## Track these prompts automatically Checking by hand works once. To see whether you are gaining or losing ground, run the same prompts on a schedule and keep every answer. AEOmeter does that from your own Chrome with your own AI accounts, saves the original answer and its sources, and tracks your competitors in the same answers. Copy your prompts as CSV and import them when you set up your brand. Start at https://aeometer.com/sign-up. Needs Chrome open while checks run. CSV format for import: a `prompt` column and a `tags` column with semicolon-separated tags. ```csv prompt,tags "What is the best product analytics tool?","discovery" "What are the best alternatives to Mixpanel?","alternatives" ``` ## FAQ ### Is the AI visibility checker free? Yes. It runs in your browser with no account, no API key and no server calls. Your inputs and marks are saved in this browser's local storage so you can come back to them. ### Which AI engines does it cover? ChatGPT, Claude, Perplexity and Google AI Overviews. These are the same four engines AEOmeter tracks. ### Why don't the prompts include my brand name? A prompt like "Is Acme any good?" will mention Acme every time. That tells you the AI knows you exist. It says nothing about whether buyers find you when they ask for a recommendation, which is what the mention rate measures. ### Why is No answer left out of the score? A failed or missing answer is not a miss. Counting it as one would push your score down for reasons that have nothing to do with your brand. AEOmeter treats failed, blocked and no-AI-Overview checks the same way. ### How is this different from AEOmeter? The checker is a manual snapshot. AEOmeter runs your prompts on a daily schedule in your own Chrome, keeps every answer with its cited sources, and shows your mention rate, citations and share of voice against competitors over time. Your Chrome has to be open for checks to run. ### Can I import these prompts into AEOmeter? Yes. Click Copy prompts as CSV and paste the result into the prompt import in AEOmeter. Each prompt keeps its intent as a tag. ## Related - [Track brand mentions in ChatGPT](https://aeometer.com/guides/track-brand-mentions-in-chatgpt): Turn this one-off check into a weekly habit, by hand or with software. - [How to choose prompts](https://aeometer.com/guides/choosing-prompts): Write prompts that match how your buyers ask, and avoid the ones that flatter you. - [Methodology](https://aeometer.com/methodology): How AEOmeter calculates mention rate, citations and share of voice. --- - Web page: https://aeometer.com/tools/ai-visibility-checker - Start tracking your brand: https://aeometer.com/sign-up - All pages for AI agents: https://aeometer.com/llms.txt
