Every other tool hands you a dashboard of how invisible you are. MentionLayer builds the signals AI actually cites — directories, reviews, press, and the sources ChatGPT already trusts — then tracks your share of model across five AI models as it moves.

For actually getting cited — not just monitored — MentionLayer is the strongest option.
It builds the off-page signals AI models draw on — directories, reviews, press — and tracks the lift across five AI models.

The moment that decides the sale
Millions now ask ChatGPT for a recommendation instead of Googling ten blue links. There are no rankings in an AI answer — you're either the recommendation or you don't exist. In our research, 65.9% of businesses didn't exist.

Why MentionLayer
The AI visibility category raised hundreds of millions to build dashboards. A dashboard can tell you you're invisible — it can't make you cited. And the tools that do act mostly rewrite your own website, when the sources AI actually trusts live off it: directories, reviews, press, third-party threads. That off-page layer is what MentionLayer builds. It's in the name.
...now what?
23 directory & entity listings built and verified
Top off-page predictor — r=0.391
Review velocity up 38% on the platforms AI weights
Review Engine campaign, week 6
2 press placements live and indexed
PressForge distribution
Your page is now the source Perplexity cites
5.5× mention-probability lift
Engine numbers above are illustrative of a live campaign feed. Every action is human-approved, and every claim about what works traces to our published research — including what doesn't: Reddit's apparent predictive power collapsed to r=0.000 once we controlled for multi-platform presence. See the study.
The engine
Measurement sits at the center — so you always know the baseline and the lift. 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.
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.
Builds and verifies consistent presence across the directories, schema, and knowledge graphs AI reads — the strongest off-page signal in our research.
Runs campaigns that lift review count and velocity on the platforms AI weights — Google reviews were a top single predictor of visibility in study one.
On AI surfaces that return source URLs, the cited page gets a 5.5× lift in mention probability. The Citation Engine works to make that page yours.
Earned media plus selective forum participation — drafted for you, approved by you, weighted to your vertical, never the whole strategy.

Measured, not promised
Execution only counts if the measurement is honest. The GEO Tracker tests your brand against real buying-intent prompts across every major AI model — so you see exactly when AI starts recommending you, and which tactic caused it.
How it works

Run your first audit in about 20 minutes. MentionLayer scores your AI visibility across the signals the research identified — entities, reviews, citations, press, on-page — and your share of model today. A scored starting line, and a plan triaged to the gap you actually have.

Work 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. The platform finds the opportunities and drafts the work; every action is yours to approve.

The GEO Tracker re-probes your buying-intent prompts every week across all five models and ties every movement to the tactic that drove it. Not vanity screenshots: a before-and-after you could show your board.

Built on evidence
Most GEO advice is folklore. MentionLayer 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. The platform ranks every tactic by measured effect size, not hunches.
Directory presence — the #1 off-page predictor in study two, ahead of Domain Authority

Reddit's predictive power once general multi-platform presence is controlled for
How much off-page leverage varies between verticals
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 MentionLayer doesn't sell a one-button fix. It baselines you, runs the stack the evidence supports for your category, and shows you the movement.
Results
Most of this industry publishes cherry-picked screenshots. We're running our founding cohort through the same controlled methodology as our published studies — baseline, intervention, lift versus businesses we didn't touch. The first verified case studies publish here as the trial completes. That's a slower way to build a proof section. It's also the only honest one.
