For the rows agreed in writing: what happens next: in the 30 minute conversation we confirm the scope, the delivery date and the terms with you. The written agreement then fixes the price shown here, and no payment is taken before it.
What we deliver and when
- A monthly category briefing, a quarterly member session with our researchers, studies 7 days before public release and member questions answered in a monthly note.
- A searchable corpus of every Absence Index answer from ChatGPT, Claude, Perplexity, Google AI Overviews and Google AI Mode with its receipt, filterable by engine, vendor, category and date, with CSV export and read-only access through our API and assistant connector.
- Captures between public releases, and alerts when a followed vendor's naming count changes between captures.
Who it is for
Marketers, analysts and agencies who follow how the five engines answer buyer questions across categories and want the evidence between our public releases.
Included
- Up to 5 named users per company.
- Quoting and citing the data with attribution.
- Every count with its base and capture date. An unlisted vendor is not a measured absence.
Not included
- Bulk redistribution of the corpus.
- Measurement of your own questions, which is the Question Tracking Plan or the $19 live question.
Method and receipts
Every count we report comes from our published method, version 1.1: the base and the date beside each figure, failed captures listed apart from the valid base, and a receipt kept for every observed answer. Read the method.
Terms
- Billed monthly, month to month; cancel before the next renewal. No minimum term.
- Agreed in writing before payment, with no automatic enrollment.
- We do not promise any ranking, placement, traffic or revenue result. What the engines say is recorded on stated dates.
Questions buyers ask
Is the Index still open to everyone?
Yes. Public releases stay open under their published license. Membership adds search across releases, alerts and the captures between releases.
Can we use the data in our reports?
Yes, with attribution. The corpus itself cannot be redistributed in bulk.
Does membership measure our own questions?
No. That is the Question Tracking Plan or a $19 live question.
