3,733 businesses studied across 5 AI models

When AI recommends a business in your category, is it you — or your competitor?

We ran the largest controlled study in the field — 1,004 then 2,729 businesses, 5 AI models — to find the exact off-page signals that get a business cited by ChatGPT, Perplexity, Gemini, and Google's AI. Then we run those signals for you and measure the lift against your baseline.

The audit is free, no credit card. The six-week study program is $500 (normally $2,000) while seats last.

The problem

Your SEO is invisible to AI

Millions now ask ChatGPT for recommendations instead of Googling. Traditional SEO doesn't influence what AI models recommend. Your competitors are already in those answers — you're not.

The platform

We don't guess at GEO. We dose the signals your category actually responds to.

Measurement sits at the center. Around it, the execution arms our research ranked highest — led by the strongest off-page predictor we found, directory and entity presence, which in our second study overtook Domain Authority itself.

Measurement core

GEO Tracker

Every tactic is measured against a baseline. The Tracker tests your brand against real buying-intent prompts across ChatGPT, Perplexity, Gemini, Claude, and Google's AI Overview — so you see your share of model move, and which lever moved it.

Top predictor

Entity & Directory Sync

The strongest off-page signal in our research. Consistent identity and presence across the directories, schema, and knowledge graphs AI reads.

Review Engine

Review count and velocity on the platforms AI weights — Google reviews were a top single predictor of visibility in study one.

Be the Cited Source

On the AI surfaces that return source URLs, being the page cited tracked with a 5.5× lift in mention probability. We work to make that page yours.

Press & Citation Engine

Earned media plus selective forum participation — a supporting signal, weighted to your vertical, never the whole strategy.

A note on Reddit: it's real, but it's not the headline. In our second study, Reddit's apparent predictive power collapsed from r=0.333 to r=0.000 once we controlled for general multi-platform presence. So we treat forum work as one honest, vertical-dependent input — not the core. See the study.

How it works

Three steps. Measurable results.

Baseline
01

Baseline

We measure your AI visibility across the signals the research identified — entities, reviews, on-page, citations, press — and your share of model today. You get a scored starting line and a plan triaged to the gap you actually have.

Dose the signals
02

Dose the signals

We run the highest-leverage arms first: entity and directory presence, review velocity, becoming the cited source — plus selective press and forum work where your vertical rewards it. Every action is human-approved.

Measure the lift
03

Measure the lift

Watch your GEO score and share of model move in near real time. See which AI models recommend you, track competitors, and tie movement back to the tactic that caused it.

The proof is the research

We measured what actually moves AI visibility

Most GEO advice is folklore. Ours is built on two published studies of 3,733 businesses across five AI models — and a third, controlled before-and-after trial now in recruitment.

Read the AI Visibility Index research

AI visibility is a system, not a single lever. No one off-page signal dominates once you control for the rest — and which signals matter shifts sharply by industry. So we don't sell a one-button fix. We measure your baseline, run the stack the evidence supports for your category, and show you the movement.
