What Should an LLM SEO Tool Actually Measure?
What should an LLM SEO tool measure?
An LLM SEO tool, also sold as an LLM visibility tool, should record whether ChatGPT, Perplexity and Google AI Overviews mention, recommend or cite your business for a fixed prompt set, keeping every answer and source URL. BaaDigi's own tracker ran 88 prompts across three engines and kept 1,429 answers with each cited link (Aug 18–31 2026). A score without the raw answers behind it is not worth paying for.
What matters most for a local business?
Check whether the tool can test your actual services and locations, identify the correct business, and show each engine separately. Confirm how many prompts, runs, locations, and exports the price includes. A larger dashboard is not useful if you cannot verify a result or act on the information it provides.
Can an AI agent actually use your website?
AI agents are starting to visit sites on a customer's behalf — comparing companies and requesting quotes. We run the same agentic browsing checks Google built into Chrome and show you what an agent hits when it lands on your site. No email to run it.

What should the measurement distinguish?
Separate mentions, recommendations, citations, and factual accuracy. A tool may detect your company name correctly while missing that the answer describes the wrong business with a similar name. Inspect the location, domain, and service details during a trial.
| Measure | Question it answers | Check in a trial |
|---|---|---|
| Business mention | Was your company named? | Aliases and similarly named businesses |
| Recommendation | Was it presented as a suitable option? | Whether the surrounding sentence supports that label |
| Website citation | Was your domain linked as a source? | The actual URL, not merely a domain count |
| Answer accuracy | Were the service and business facts correct? | Location, phone, scope, and unsupported claims |
| Collection quality | Did the intended test run successfully? | Timeouts, unavailable features, retries, and missing evidence |
Why does the collection method matter?
Ask whether results come from a consumer app, an API, a search service, or another collection method. Record model or mode information where available. Do not assume one product's output reproduces every customer's experience of a different product.
OpenAI's search documentation explains that local and saved context can affect ChatGPT searches. That makes test conditions part of the evidence. The tool should disclose what it controls and what it cannot reproduce.
How should a tool define share of voice?
Require the actual calculation. A percentage might mean the share of completed answers mentioning you, the share of all company mentions, or a weighted score. Those are different measures. Ask to see the numerator, denominator, time period, and treatment of multiple mentions in one answer.
Show failed tests separately instead of silently counting them as absences. Keep each engine visible, even when the product also reports an aggregate. An aggregate can hide missing coverage or a problem affecting only one collection method.
What is a useful acceptance test before paying?
- Supply real prompts. Include your core services, actual cities, a research question, and a branded accuracy check.
- Inspect a sample answer. Confirm that the business detection and citation labels match the evidence.
- Check a missing result. Establish whether it was a completed answer without your company or a collection failure.
- Export the evidence. Confirm you can retain prompts, timestamps, answers, and URLs for later comparison.
- Review the billable limits. Count engines, locations, repeated runs, seats, and retention requirements.
- Make a real decision. Identify one correction the report supports. If it cannot support a decision, more scores may not help.
Use the AI search visibility checking workflow to interpret the trial. If ongoing measurement is the main need, the acceptance test above is the requirements list; run it against each vendor with the same prompts.
What does a real run look like?
Our own collection is a useful yardstick for any tool you trial. Between August 18 and 31, 2026 we ran 88 prompts on Mondays, Wednesdays and Fridays through ChatGPT, Perplexity and Google AI Overviews. ChatGPT and Perplexity each returned 511 usable answers; Google AI Overviews returned 407 after errors were excluded, for 1,429 answers in total. Each answer was stored with its full text and every cited URL, which is how we can say reddit.com was cited 657 times and baadigi.com 382 times, and how we can show the per-engine split (Perplexity cited reddit.com 382 times; Google AI Overviews cited google.com 310 times). The citation study publishes the table. Ask any vendor to show you the same level of detail for your prompts before you pay; the LLM SEO guide explains what to do with it once you have it.
What should you avoid claiming from the data?
Do not call a mention rate a sales conversion rate or infer the assistant's full selection logic from one cited page. A report can reveal incorrect information and observable changes. It cannot guarantee that a particular edit will produce a future recommendation.
Use technical findings for their actual scope. A crawl failure calls for an access investigation. A missing service description calls for a content review. Neither finding justifies promising a ranking timetable. The manual ChatGPT check is a useful starting procedure.
How should you compare prices?
Compare the total cost for the same prompt set, engines, locations, run frequency, exports, and review effort. Use current vendor offers; this guide does not establish a universal software price range.

Who does AI recommend, and which sources does it cite?
More people ask ChatGPT and AI search “who's the best contractor near me?” every day. See if AI names you — or sends the job to someone else. No email to run it.

Frequently Asked Questions
Are an LLM visibility tool and a rank tracker the same?▼
No. A rank tracker records positions in a defined search result. An LLM visibility tool inspects generated answers using its own collection and scoring method. Keep the two reports separate.
Does every tool cover the same AI engines?▼
No. Coverage, modes, locations and collection methods depend on the product and plan. Ask for the current list and run a sample with your own service-and-city questions before assuming a logo on the pricing page means full coverage.
What should I ask about a share-of-voice score?▼
Ask for the numerator, the denominator, the engine coverage, the prompt set, the weighting and the time period. Find out whether two mentions of your company in one answer count once or twice, and whether failed runs are dropped or reported. In our own August 2026 run, Google AI Overviews returned 511 rows but only 407 usable answers; a tool that silently counts the errored rows as absences would cut your apparent share of voice for no real reason. Different definitions produce different percentages from the same answers, so insist on seeing the underlying counts per engine.
Should I buy software or a one-time audit?▼
Buy software when someone will review and act on recurring results. Buy a defined audit when you need findings and an action plan at a point in time. Compare scope, evidence, exports and total cost; neither guarantees future recommendations or inquiries.
How much does BaaDigi’s visibility analysis cost?▼
The starting AI Search Visibility Checker is free. The AI Visibility Audit is a flat $497 for one business and one market. It is a one-time diagnosis, not a monitoring subscription.

What Should an AI Tracker Measure?
An AI visibility tracker records selected AI answers over time so you can compare mentions, citations and factual descriptions under documented conditions. Its value depends on a stable question set, reliable business matching and reviewable evidence. A changing score is a prompt to investigate, not proof that an edit caused a gain or loss.
How Do You Analyze AI Search Visibility?
Turn an AI visibility report into a useful action list. Check test conditions, citation sources, failed runs, and business details before drawing conclusions.
