AI VISIBILITY
INDEX
METHODOLOGY
How We Measure Which Businesses
AI Sees, Cites and Recommends
The AI Visibility Index by Chief AI Advisors is an independent
research initiative designed to measure how businesses appear
within AI-generated search, discovery and recommendation
environments.
Rather than asking which businesses rank highest in traditional
search results, the Index examines a different question:
When consumers ask AI who to hire, which businesses
actually make the answer?
Each Index uses a defined geographic market, industry-specific
consumer prompts and observed AI responses to measure the
relative visibility of businesses within that market.
Recommendation Visibilty
Share of Voice
Cross Platform Visibility
Citation & Authority
What We Measure
AI visibility is more complex than a single search ranking.
A business may appear frequently on one AI platform, rarely on another, or be mentioned without being prominently recommended. AI systems may also rely on very different sources when forming their answers.
The AI Visibility Index therefore evaluates visibility across four core dimensions.
Recommendation Visibility
How often and how prominently does a business appear when AI is asked for relevant recommendations?
We examine whether businesses appear within responses to high-intent consumer prompts and the prominence of those appearances.
Businesses that are repeatedly surfaced as relevant recommendations demonstrate stronger observed visibility than businesses that appear rarely or incidentally.
Share of Voice
How much of the observed AI recommendation landscape does a business capture compared with its competitors?
Share of Voice measures a company’s relative presence across the prompt set.
This helps reveal whether AI recommendations within a market are distributed among many businesses or concentrated around a smaller group of companies.
Cross-Platform Visibility
Does the business appear consistently across different AI search and answer environments?
AI platforms do not necessarily produce the same recommendations.
A business may be highly visible within one environment while largely absent from another.
Where multiple AI platforms are included in an Index, we examine the consistency of a company’s visibility across those environments.
Citation & Authority
What sources appear to support AI’s understanding and recommendations of a business?
AI-generated answers can draw upon company websites, directories, review platforms, publications, local resources and other third-party sources.
We examine the citations and supporting sources observed during testing to better understand the information environment surrounding the businesses being recommended.

How Each Market Is Tested
Every AI Visibility Index begins with a clearly defined:
Industry
Geographic market
Research period
Prompt set
AI platform set
For example, an Index examining plumbing companies in Greater Victoria may include prompts representing several types of real consumer intent.
These might include:
“Who are the best plumbers in Victoria, BC?”
“Recommend a reliable plumber in Greater Victoria.”
“Who should I call for emergency plumbing in Victoria?”
“Which Victoria plumbing companies have a strong reputation?”
“Who installs hot water tanks in Greater Victoria?”
The objective is not to repeatedly ask the same question using slightly different wording.
Instead, the prompt set is designed to represent the different ways a real customer might research, compare and select a provider.
Businesses Are Discovered Through the Results
The AI Visibility Index is not designed around a predetermined list of winners.
Businesses are primarily identified through the observed AI responses themselves.
When the tested AI systems mention, cite or recommend businesses in response to the standardized prompt set, those entities become part of the observed competitive landscape.
Where appropriate, additional known market participants may also be monitored to understand whether established businesses are consistently absent from AI-generated recommendations.
This approach allows us to measure who AI is actually surfacing, rather than simply testing a hand-selected list of companies.
Standardized Testing
Consistency is essential when comparing businesses.
Within each Index edition, the same core prompt set and testing framework are used across the selected AI environments.
Results are collected during a defined research period so that businesses are being compared against the same general market conditions.
The specific:
- AI platforms tested
- geographic boundaries
- industry definition
- number and type of prompts
- research dates
are disclosed within each published Index.
From Observations to an AI Visibility Score
Observed results are evaluated using the four dimensions of the Chief AI Visibility Index:
Recommendation Visibility
Share of Voice
Cross-Platform Visibility
Citation & Authority
These measurements are combined to provide a comparative indication of each business’s observed AI visibility within the tested market.
The resulting score is intended to make relative visibility easier to understand.
An AI Visibility Score is not a quality score.
It does not measure workmanship, professional competence, customer service, value, safety or whether one company is objectively better than another.
It measures observed visibility within AI-generated search and recommendation environments during the stated research period.
AI Visibility Is Dynamic
Unlike a traditional directory listing, AI-generated answers can change.
Different platforms use different models, retrieval systems, data sources and methods for generating responses.
Results may also evolve as:
- AI platforms and models change
- websites are updated
- new content is published
- reviews and reputation signals change
- third-party citations appear or disappear
- business information changes
- competitors strengthen their digital presence
- AI systems gain access to new information
For that reason, each AI Visibility Index should be viewed as a snapshot in time, not a permanent ranking.
The research date shown on each Index is an important part of interpreting the results.
Why Results May Differ Between AI Platforms
There is no single universal AI search result.
One platform may strongly recommend a business that another platform barely mentions.
This can happen because AI systems differ in the information they can access, the sources they rely upon, how they interpret a query and how they determine which entities to include in an answer.
Those differences are precisely why Cross-Platform Visibility is an important part of the Index.
Being visible to one AI system does not necessarily mean a business is broadly visible across the AI discovery landscape.
What the Index Does — and Does Not — Tell You
The Index Can Help Show:
Which businesses AI systems are currently surfacing.
How recommendation visibility is distributed within a market.
Which businesses demonstrate stronger cross-platform visibility.
Which sources and citations frequently appear around AI recommendations.
Where established businesses may be significantly underrepresented.
How the competitive AI visibility landscape changes over time.
The Index Does Not Determine:
Which business provides the best service.
Which company a consumer should ultimately hire.
Whether a business is professionally qualified or appropriate for a specific job.
Whether an AI system’s recommendation is factually correct.
Whether a company will appear in every future AI-generated response.
Independence & Commercial Relationships
The AI Visibility Index is produced by Chief AI Advisors as an independent research initiative.
Businesses do not purchase their position within an Index, and payment is not used to improve a company’s ranking.
Chief AI Advisors may separately provide AI visibility, digital authority, search, automation or advisory services to businesses that appear within markets we study.
Where a material commercial relationship could reasonably affect the interpretation of a published Index, it will be disclosed.
Corrections & Business Information
AI systems can occasionally associate outdated, incomplete or incorrect information with a business.
We welcome factual corrections involving items such as:
Business name
Website
Location
Service area
Business status
Entity identification
A factual correction does not guarantee a change in ranking because rankings reflect the AI responses observed during the stated testing period.
Where appropriate, corrections may be incorporated into future editions.

Why We Created the AI Visibility Index
The way customers discover businesses is changing.
Traditional search remains important, but consumers increasingly have the ability to ask AI:
Who should I hire?
Which company would you recommend?
Who is trusted for this particular problem?
Instead of presenting a page containing dozens of possible websites, an AI system may provide only a handful of recommendations.
That creates a new competitive question for established businesses:
Is AI able to understand, trust and recommend you?
The AI Visibility Index was created to make that emerging landscape more measurable and transparent.
Market Visibility vs. Business Readiness
The AI Visibility Index measures what is happening in the market.
It tells us which businesses are appearing within observed AI recommendations and how their visibility compares with competitors.
The Chief AI Business Diagnostic asks a different question:
How prepared is your individual business for the AI era?
The Diagnostic examines broader areas including:
AI Efficiency Opportunity
Where AI and automation could reduce repetitive work, recover time and improve operations.
AI Visibility Readiness
Whether the business has the clarity, authority and digital signals that help AI systems understand and potentially recommend it.
Digital Foundation
Whether the website and broader digital presence support search visibility, AI visibility and conversion.
Together, the Index and Diagnostic provide two different perspectives:
The Index shows the competitive landscape.
The Diagnostic examines the individual business.

Frequently Asked Questions
Common questions about the methodology behind the AI Visibility Index, including how markets are tested, how businesses are discovered, what the rankings measure, and why results can vary between AI platforms and over time. The Index is designed to provide a transparent, repeatable view of how businesses are being surfaced, cited and recommended within the evolving AI search landscape.
How is the AI Visibility Index calculated?
The AI Visibility Index evaluates observed AI search performance across four core dimensions: Recommendation Visibility, Share of Voice, Cross-Platform Visibility, and Citation & Authority. These measurements are used to compare the relative visibility of businesses within a defined industry, geographic market and testing period.
How do you choose the prompts used in each Index?
Each prompt set is designed around realistic questions a potential customer might ask when researching or choosing a business. Prompts cover different forms of commercial intent, including general recommendations, reputation, specific services, problems, comparisons and location-based searches rather than repeatedly testing variations of the same question.
Are the businesses chosen before the research begins?
Not necessarily. Businesses are primarily discovered through the AI responses themselves. When AI platforms mention, cite or recommend companies in response to the standardized prompt set, those businesses become part of the observed competitive landscape. Known businesses may also be monitored to identify companies that are notably absent from AI recommendations.
Can a business pay to be included or rank higher?
No. Businesses cannot purchase inclusion, placement or a higher ranking in the AI Visibility Index. Rankings are based on observed AI search visibility during the stated research period and are independent of any commercial relationship with Chief AI Advisors.
Businesses can, however, improve their AI visibility. Chief AI Advisors works with companies to identify why they may be underrepresented in AI-generated recommendations and strengthen the authority, content, citations, entity signals and digital foundation that influence how AI systems understand and recommend them.
Improvement does not guarantee a particular ranking, but it can strengthen a business’s ability to be discovered, understood and considered by AI platforms.
Why can rankings differ between AI platforms?
Different AI platforms use different models, retrieval technologies, information sources and methods for generating recommendations. A company that appears prominently on one platform may have significantly less visibility on another, which is why cross-platform consistency is an important part of the research.
How often can AI visibility rankings change?
AI visibility is dynamic and rankings can change as AI models evolve, websites are updated, new content and citations appear, reviews change and competitors strengthen their digital presence. Each published Index therefore represents a snapshot of observed visibility during a specific research period.
Does a high AI Visibility Score mean a company is the best business?
No. The Index measures AI visibility, not business quality. A high score indicates that a company was more visible within the tested AI search and recommendation environment. It does not evaluate workmanship, professional competence, customer service, pricing or whether a consumer should choose one business over another.
What are Citation & Authority Signals?
These are the external and owned sources that may help AI systems understand and validate information about a business. Depending on the market and platform, these can include company websites, directories, review platforms, industry resources, publications, local sources and other authoritative references observed during testing.
Why might an established business not appear in AI recommendations?
Strong real-world reputation or traditional search rankings do not automatically produce strong AI visibility. AI systems need to clearly understand what a business does, where it operates and why it may be a credible recommendation. Gaps in content, entity clarity, citations, authority signals or broader digital presence can contribute to inconsistent AI visibility.
Can a business request a correction to the Index?
Yes. Businesses can contact Chief AI Advisors regarding factual information such as their business name, website, location, service area or operating status. A factual correction does not automatically change a ranking because published rankings reflect the AI responses observed during the stated research period.
