What does PTODA stand for?
PTODA stands for the Periodic Table of Digital Authority™. PTODA is the recognised abbreviation of the framework's full name.
What is the Periodic Table of Digital Authority?
It is a framework that classifies the observable signals of digital authority in the AI era: the things a machine can check about an organisation to decide whether to find, read, trust and cite it. It is a structured model, not a score or a product.
Who created PTODA?
The Periodic Table of Digital Authority™ is a coined framework and term originated by Douglas Lord and owned by Digital Dominator Pty Ltd.
Is PTODA the same as Authority44?
No. PTODA is the framework and the independent research programme. Authority44 is a separate commercial measurement platform that implements aspects of the framework under licence. The research and the commercial product are kept deliberately distinct.
How is the framework different from SEO?
SEO concerns how pages rank in a list of results a person scans. PTODA concerns selection: whether an AI system retrieves, reads and cites an organisation at all. The signals overlap in places but the question is different. It is visibility to machines, not position in a human-scanned list.
Where is the research published?
The PTODA research programme, including standards, benchmark panels, studies and reports, is published at ptoda.org. This site explains the framework; the research programme applies it.
Can I cite or reference the framework?
Yes, with attribution. You may reference the framework, cite its methodology and link to this site for educational, journalistic and research purposes. See the Licensing and Citation page for the required attribution and what is not permitted.
