When buyers research who to hire, they ask ChatGPT, Google’s AI, Perplexity, and Claude who to consider — and that handful of names becomes the shortlist. SIGNALS finds where your company is invisible across all four engines, does the work to get you cited, and measures the movement.
SIGNALS is the AI-visibility (AEO) framework, the intelligence platform that measures it, and the practice that does the work — for industrial and professional firms. It is a BlackSig Systems company.
A seven-dimension, weighted scoring system for how citable a page is to AI engines. Each weight is derived from measured effect size across four peer-reviewed studies (Princeton GEO, ConvertMate, Discovered Labs) spanning 2M+ citations. Alignment is the dominant signal — the only dimension that survives controlling for domain authority.
Behind the score, a four-stage pipeline — Retrieval → Parsing → Ranking → Generation — pinpoints exactly where a page drops out before it can be cited.
Visibility is decided on a company’s own pages, and in the CIP-skid category no fabricator is named across all four engines at once. Share of voice by engine (% of runs naming the firm): IPEC — Google AIO 40, ChatGPT 100, Perplexity 0, Claude 100, combined 60. GEA — 20, 40, 80, 100, combined 60. CSI (Central States Industrial) — 80, 0, 20, 60, combined 40. Arcadia Equipment — 20, 0, 20, 100, combined 35. Agidens — 0, 60, 20, 20, combined 25.
A free, PULSE-powered visibility assessment maps exactly where your company is cited and where it is invisible across all four engines, against the competitors winning your category. SIGNALS — a BlackSig Systems company.
