Measure ChatGPT visibility without confusing a spot check for a benchmark
See whether AI answers mention your brand, who appears instead, and which sources shape the answer. Every run preserves the questions, answers, citations, and provider coverage behind the result.
Directional API-grounded measurement, not a replica of a personalized ChatGPT consumer session.
What it measures
Four metrics, each tied to answer evidence
Discovery visibility
How often the brand appears in neutral buyer questions that do not plant its name.
Prominence
Whether the brand leads the answer, makes the shortlist, or appears incidentally.
Competitor share of voice
Which selected competitors appear across the same answer set and how often.
Owned citations
How often eligible answers cite the submitted canonical domain or a subdomain.
Choose the measurement model
The right ChatGPT SEO tool depends on the decision
| Approach | Best for | Important tradeoff |
|---|---|---|
| Typing prompts into ChatGPT | Fast spot check | Personalized sessions, changing prompts, no controlled evidence |
| Continuous AI monitoring | Ongoing trend tracking | Recurring subscription and changing prompt panels |
| 100 Questions benchmark | Comparable baseline or rerun | Frozen questions, four providers, stored answers and citations |
For the broader market, compare continuous monitoring, enterprise research, SEO suites, and fixed benchmarks in the AI SEO tools guide.
Controlled workflow
From subject definition to evidence-linked action
- 01
Define the subject
Submit the brand, canonical domain, category, market, aliases, and selected competitors.
- 02
Freeze the questions
The run creates 20 neutral discovery questions and 5 direct diagnostic questions, then freezes them.
- 03
Run four providers
The identical set is sent through web-grounded OpenAI, Claude, Gemini, and Grok provider calls.
- 04
Review the evidence
Metrics link back to stored answers, cited URLs, missed questions, competitors, and recommended actions.
ChatGPT discovery foundation
Access matters, but access does not guarantee inclusion
OpenAI documents OAI-SearchBot separately from GPTBot: publishers can control search discovery independently from model training. A public page still needs clear entity facts, useful answers, trustworthy evidence, and third-party corroboration before it becomes a safe recommendation.
Read the official OpenAI publisher guidance, then use the LLM SEO guide for the broader content and authority workflow.
Questions before choosing a tool
ChatGPT SEO tool FAQ
What is a ChatGPT SEO tool?
A ChatGPT SEO tool measures or improves how a brand appears in AI-generated answers. Useful tools separate technical crawlability, prompt monitoring, content optimization, and controlled visibility measurement instead of hiding them inside one unexplained score.
Can a tool guarantee that my brand ranks in ChatGPT?
No. ChatGPT answers vary by model, search behavior, available sources, prompts, location, and time. A defensible tool can measure a controlled snapshot and preserve evidence; it cannot guarantee inclusion or reproduce every consumer session.
Does 100 Questions use the ChatGPT consumer interface?
No. It uses API-grounded provider calls through Vercel AI Gateway. That sacrifices consumer-interface personalization in exchange for identical questions, controlled provider comparisons, stored evidence, and repeatable reruns.
Why compare ChatGPT with Claude, Gemini, and Grok?
A brand can be visible in one assistant and absent in another because providers use different models, search integrations, and source-selection systems. Multi-provider context shows whether a result is broad or dependent on one ecosystem.
How often should I rerun a ChatGPT visibility benchmark?
Rerun after substantive changes have had time to be crawled: new comparison pages, clearer entity facts, original research, earned third-party coverage, or important technical fixes. Reusing the frozen questions makes the comparison more meaningful.
