Every signal that determines whether AI systems - ChatGPT, Google AI Overviews, Perplexity, Gemini - recommend your business or skip it. 44 elements. 8 authority groups. One framework.
The Periodic Table of Digital Authority™ is the visual representation of the Digital Authority Signal System™ — the proprietary scoring methodology behind AUTHORITY44™. The visible periodic table shows 44 core elements (matching the AUTHORITY44 brand). The full underlying system extends to 63 coded signals across 8 authority groups, scored via a weighted composite formula and an original inverse penalty model.
Conceived and invented by Doug Lord no later than November 2024 and first published in a live product environment at authority44.ai in early 2026. Unlike static SEO tables that describe ranking factors, the Digital Authority Signal System produces a measurable Authority Score (0–100) used for analysis, benchmarking, and optimisation.
OG01 scores your business across the most critical authority signals and tells you exactly which elements to fix first.
