Make sure AI search recommends you.

Buyers ask ChatGPT, Google’s AI Overviews, Perplexity, and Claude which companies to consider before they talk to sales. Two things can go wrong:

Missing from answers: on the questions that build a shortlist, they name your competitors instead.
Out-of-date details: when they do describe you, they sometimes use old pricing or products.

Two services

AI Visibility Program (also called AEO, GEO or AI SEO): does AI search name you when buyers ask? We find the buyer questions where you’re missing, do the work on your pages and across the web to get you cited, and measure the movement. From $3,000 a month, scoped after the free visibility assessment. Pricing.
AI Answer Accuracy: is what AI search says about you still true? We log every stale claim across the four engines, trace where it comes from, fix the sources and prove it changed. Accuracy Audit $1,500; Correction Sprint from $3,000; Accuracy Monitor $500 a month.

SIGNALS is the AI-visibility (AEO) framework, the intelligence platform that measures it, and the practice that does the work. It is a BlackSig Systems company.

The SIGNALS framework: the proprietary system for AI citation readiness

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.

Structure (12%): content organized for AI extraction
Intent (10%): adjacent buyer questions covered
Grounding (13%): claims sourced and verifiable
Newness (5%): recency visible on the page
Alignment (35%): page vocabulary matches how buyers ask (the dominant signal)
Language (10%): titles and openings phrased for buyer queries
Substantiation (15%): third-party validation across the web

A four-stage pipeline (Retrieval, Parsing, Ranking, Generation) shows where a page drops out before it can be cited.

From our research: one category, measured

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.

What we do: measure, change, prove

Measure: PULSE maps where you’re cited and where you’re invisible across the four engines, compared with the competitors winning your category.
Change: the work on your own pages: structure for extraction, vocabulary that matches how buyers ask, grounded and sourced claims, and substantiation across the web.
Prove: we re-measure and show the movement. Perplexity and Google AI Overviews usually move first; ChatGPT and Claude take longer. We report the results either way.
