Glossary
Terms and metrics used across LLM Authority Index.
A reference for the measurement framework, AI search mechanics, and economic concepts that appear in our reports and platform.
A
AI Commercial Momentum
AI Commercial Momentum is the change over time in how frequently a company, brand, or product is recommended by AI systems for commercially relevant, generally unbranded questions.
The term is broader than a simple visibility metric. It describes the research hypothesis that persistent changes in AI recommendation behavior may contain information about future consumer consideration, branded search, direct traffic, customer acquisition, or other commercial outcomes. That relationship is being tested prospectively and has not been established as a predictor of revenue, earnings, valuation, or stock returns.
Read MoreAI Divergence Candidate
An AI Divergence Candidate is a company whose AI recommendation movement meets predefined magnitude, directional uncertainty, and cross-platform breadth rules for deeper commercial and financial follow-up.
Under the current V0 framework, a Positive AI Divergence Candidate requires a recommendation-coverage increase of at least 5 percentage points, an exploratory interval above zero, and improvement across at least four AI platform families. A Negative AI Divergence Candidate requires the reverse pattern. The label is a research classification, not a stock rating or investment recommendation.
Read MoreAI Investor Signal
An AI Investor Signal is a measurable change in how AI systems surface, compare, rank, or recommend a company that may contain information relevant to future commercial performance or investor expectations.
A change in AI visibility is not automatically an investor signal. In the LLM Authority Index framework, investor relevance must be tested prospectively. A useful signal should be measured before the downstream outcome, economically connected to the company or tracked entity, reasonably persistent, and incrementally informative beyond conventional data investors already have.
Read MoreAI Ranking Position
AI Ranking Position measures where a brand appears inside the AI answer, not just whether it appears.
The reports treat answer position as commercially meaningful because AI-generated recommendations are not neutral lists; users tend to notice and trust the first few names most. The system determines ranking by looking for an explicit ordered list or "best / top / first / second" structure, and if none exists, it defaults to first tracked-company mention order. This is included because being ranked first, second, or third has different likely outcomes than being buried lower in the response, even when overall visibility looks similar.
AI Recommendation Coverage
AI Recommendation Coverage is the percentage of eligible AI observations in which a company, brand, product, or other tracked entity receives a valid recommendation.
In the longitudinal AI Investor Signals framework, recommendation coverage is generally calculated across matched prompt-platform observations. It measures absolute recommendation frequency, not simple presence and not competitive recommendation share. A company can appear in an answer without being recommended, and it can increase recommendation coverage while losing recommendation share if competitors improve faster.
Read MoreAI Recommendation Momentum
AI Recommendation Momentum is the direction and magnitude of change over time in how often AI systems recommend a company, brand, product, or other tracked entity across a comparable set of commercially relevant prompts.
In the current LLM Authority Index framework, the primary implementation measures the change in recommendation coverage across matched prompt-platform observations. AI Recommendation Momentum is an AI-side measurement. It should not be interpreted as revenue momentum, earnings momentum, stock-price momentum, or financial performance without separate validation.
Read MoreAI Recommendation Share
AI Recommendation Share is the portion of recommendation allocations captured by a company within a defined competitive category or recommendation set.
Recommendation share measures competitive selection, while recommendation coverage measures how often the company is recommended across eligible observations. The two can move differently. A company can improve absolute recommendation coverage while losing recommendation share if competitors improve faster.
Read MoreAI Recommendation Share Gap
The AI Recommendation Share Gap is the difference between a company's AI Recommendation Share and a comparable measure of real-world market share.
AI Recommendation Share Gap = AI Recommendation Share - Comparable Market Share. A positive gap means the company captures a larger share of AI recommendations than its current real-world market position would suggest. A negative gap means it captures a smaller share. The gap is descriptive until longitudinal research establishes whether it contains information about future commercial share or growth.
Read MoreAI Revenue Index (ARI)
AI Revenue Index is a directional value metric calculated as ARS × Q × VPQ.
This is the boardroom-friendly expression of the model: how much AI-influenced demand value a brand appears to control. It is not meant as exact attribution, but as a disciplined estimate of the revenue pool associated with AI recommendation share. It is included because it gives the report a commercially legible output rather than stopping at abstract visibility numbers.
AI Share of Voice (SOV)
AI Share of Voice measures how often a brand appears in AI-generated answers compared with competitors.
This is one of the foundational metrics in the report because it answers the most basic discovery question: when people ask commercially relevant questions in AI tools, how often does the brand show up at all? It is usually calculated across a defined prompt set, cluster, platform, or total market view. Its value is that it gives a directional market-share style view of AI visibility, but it is included with an important caveat: appearance alone is not enough, because a brand can be visible without being preferred, recommended, or ranked highly. That is why SOV is always interpreted alongside ranking, recommendation rate, and citation strength.
AI Visibility Market Divergence
AI Visibility Market Divergence is a research framework for comparing a validated AI-derived commercial signal with contemporaneous investor expectations, such as analyst forecasts, company guidance, growth expectations, valuation measures, or other market information.
The term does not mean that the market is wrong or that a stock is mispriced. A divergence only identifies a potential difference between an AI-derived commercial signal and expectations already visible in financial data. The AI signal must first demonstrate prospective commercial value before market-divergence conclusions become meaningful.
Read MoreAttribute-Level Sentiment
Attribute-level sentiment measures how specific brand attributes, such as price, trust, AI features, or usability, are described.
A brand's overall sentiment may look healthy while specific attributes are weak or risky. For example, a platform may be described positively for ease of use but negatively for pricing transparency. This is included because strategy usually requires knowing what exactly is helping or hurting recommendation quality, not just whether the brand is liked in general.
Average Rank (AR)
Average Rank summarizes ranking performance by converting answer position into a point score.
The scoring model assigns 10 points to rank 1, 9 to rank 2, and so on down to 1 point for rank 10, with rank 11+ scoring zero. This allows the reports to compress many prompt outcomes into one comparable ranking measure. It is included because raw rank snapshots are too fragmented at scale; Average Rank gives a clearer view of how strongly a brand performs across an entire cluster or platform rather than in a single answer.
Average Rank When Mentioned
Average Rank When Mentioned measures how well the brand ranks only in prompts where it appears.
This isolates answer quality from answer frequency. A company might have low overall visibility but rank very strongly whenever it does appear, or it might appear often but only in low positions. This metric is included to separate those cases and prevent analysts from confusing absence problems with ranking-quality problems.
Average Rank, Cluster-Wide
Cluster-wide Average Rank measures total ranking strength across all prompts in a cluster, including prompts where the brand does not appear.
This version of AR divides total ranking points by all prompts in the cluster, so absence hurts the score. That makes it a better measure of overall cluster strength than a "when mentioned" score. It is included because it answers the tougher question: not just how well the company ranks when it shows up, but how strong it is across the full opportunity set.
B
Brand Rating
Brand Rating measures how strongly a brand is represented inside the influential evidence networks shaping AI-generated conclusions.
It is a proposed framework for measuring how strongly a brand is positioned within the network of sources, claims, and evidence that influence AI-generated answers and recommendations.
Read MoreBrand-in-Question vs Organic Appearance
This distinction separates prompts that explicitly name the brand from prompts where the brand appears without being asked for directly.
A company often performs better when it is already named in the question, but the more valuable discovery signal is whether it appears organically in non-branded prompts. This is included because branded presence measures existing awareness, while organic appearance measures real recommendation power and category relevance.
Buyer Stage
Buyer Stage indicates where a prompt sits in the decision journey, such as discovery, comparison, or evaluation.
The report architecture recognizes that prompts at different stages have different commercial implications. Early educational prompts shape category entry, while pricing and shortlist prompts influence conversion-ready decisions. Buyer Stage is included because the same visibility level can mean very different things depending on whether the user is just learning or about to choose.
C
Citation Architecture
Citation Architecture describes the sources and source patterns that appear to shape how AI systems talk about a brand.
This is one of the most important explanatory concepts in the report. AI models do not form recommendations out of nowhere; they are influenced by the domains, content types, and third-party references that repeatedly support answers. Citation Architecture captures those support structures, including official sites, editorial sources, reviews, forums, and other public references. It is included because many ranking and recommendation outcomes are driven less by brand messaging and more by the surrounding evidence environment.
Citation Moat / Citation Advantage
Citation Moat describes a durable advantage created when one brand is consistently supported by stronger and more numerous authoritative sources than competitors.
The sample reports repeatedly show that some competitors win not just because of brand strength, but because they have built an evidence environment AI systems repeatedly rely on. That produces self-reinforcing recommendation patterns. It is included because it explains why some brands are hard to displace even when the target has a competitive product.
Citation Rating
Citation Rating measures the relative influence of a source within AI citation and evidence networks.
It is a proposed framework for measuring how influential a source is within the evidence networks that shape AI-generated answers, recommendations, and conclusions.
Read MoreCitation Source Mix
Citation Source Mix shows the distribution of source types supporting AI answers, such as official sites, editorial pages, reviews, forums, and social platforms.
The methodology specifically calls for classifying citations by source type because not all evidence plays the same role. Official pages may explain products, editorial content may define "best" lists, reviews may shape trust, and forums may shape real-user credibility. It is included because understanding the mix helps explain why certain brands are framed as authorities while others are treated as alternatives or cautions.
Cited Domains
Cited Domains are the websites or root domains that appear as supporting sources in AI responses.
Tracking cited domains shows which websites are repeatedly used to support brand recommendations, explanations, or comparisons. This matters because the source of the answer often influences the framing of the answer. It is included to reveal whether the brand is supported by strong first-party and third-party evidence, or whether competitors own the domains AI systems keep leaning on.
Company-Associated Cited Domains
Company-associated cited domains are the domains most often connected to a specific brand when that brand appears in AI answers.
This metric goes beyond overall domain counts and asks which sources are effectively carrying the brand's authority. That can include the brand's own website, partner pages, editorial reviews, public discussions, or comparison sites. It is included because a company may appear often, but for fragile reasons tied to a narrow evidence base, while another brand may be supported by a broader, more durable citation network.
Competitive Gap
A Competitive Gap is the measurable difference between the target company and competitors on visibility, ranking, citation support, or framing.
The report is explicitly competitive intelligence, so it does not stop at describing the target in isolation. It compares where competitors outrank, out-cite, or out-convert the target in commercially important conversations. This is included because strategy depends on understanding not just internal weakness, but who is taking the recommendation share the target is losing.
Competitive Velocity
Competitive Velocity measures how quickly competitors are gaining or losing AI discovery ground relative to the target company.
This turns momentum into a comparative signal. Instead of asking only whether the target improved, it asks whether the target improved faster or slower than the brands it competes against. It is included because a company can post positive gains and still lose relative position if competitors are accelerating faster.
Cost Per Click (CPC)
CPC is the estimated paid-search cost associated with a keyword and acts as a proxy for commercial intent or market value.
Higher CPC often signals that advertisers value traffic in that area, which makes it a useful proxy when estimating the economic importance of prompt clusters. It is included because the report's economic layer needs a directional commercial weighting system grounded in something more concrete than opinion.
D
Discovery Economics
Discovery Economics estimates the commercial significance of AI visibility and recommendation performance.
This is the value layer that converts discovery metrics into business relevance. Rather than treating appearance in AI answers as a vanity signal, the economics layer connects visibility to directional monetary value using search demand, commercial intent, and monetization proxies. It is included because decision-makers care not just who appears in AI answers, but what those appearances are likely worth.
F
Framing Distribution
Framing Distribution classifies the role the AI assigns to a brand, such as leader, strong option, specialist, alternative, fallback, or cautionary option.
This is one of the more sophisticated parts of the methodology because it captures market role, not just tone. A brand may receive positive sentiment but still be framed as niche, secondary, or conditional. It is included because the reports are meant to explain not just whether AI mentions a brand, but what kind of market position AI seems to believe that brand occupies.
H
High-Intent Prompt Cluster
A High-Intent Prompt Cluster is a themed group of commercially relevant prompts that represent a specific buying conversation.
Examples include pricing, alternatives, trust, educational, or recruitment software prompts. Clustering matters because discovery performance varies dramatically by intent type; a brand may be strong in alternatives but invisible in pricing, or trusted in educational content but absent from shortlist prompts. Clusters are included because they make the report strategically useful: instead of one blended number, the report shows where the commercial problem actually lives.
M
Matched Prompt-Platform Cell
A Matched Prompt-Platform Cell is a normalized prompt and AI platform-family combination that can be compared across two or more observation periods.
Matched cells are used to reduce denominator drift in longitudinal AI measurement. Instead of comparing different prompt or platform populations from month to month, the methodology compares the same normalized prompt on the same platform family when possible. This makes measured momentum less sensitive to changes in the observation mix.
Read MoreMention-to-Top-1 Rate
Mention-to-Top-1 Rate shows how often a brand converts an appearance into a first-place recommendation.
This is a conversion metric rather than a visibility metric. It asks: once the brand enters the answer, how often does it become the leading recommendation? That matters because some brands are commonly present but rarely endorsed as the best option. It is included because it reveals the gap between being known and being preferred.
Mention-to-Top-3 Rate
Mention-to-Top-3 Rate shows how often an appearance turns into a top-three placement.
This is similar to Mention-to-Top-1 but slightly broader and often more stable across clusters. It is useful for diagnosing whether a brand is merely peripheral or genuinely considered competitive once it is surfaced. It is included because a company can have acceptable presence but poor conversion into commercially meaningful positions.
Monthly Momentum
Monthly Momentum tracks how the target company's AI visibility metrics change from month to month.
The system is designed for recurring reporting, so one static snapshot is not enough. Momentum shows whether share of voice, ranking, citations, and other indicators are improving, weakening, or holding flat. It is included because early movement often matters more than current size; a smaller brand gaining quickly may be strategically more important than a larger brand standing still.
N
Negative AI Divergence Candidate
A Negative AI Divergence Candidate is a V0 research classification for a company whose AI recommendation coverage declined by at least 5 percentage points, whose exploratory interval remained below zero, and whose recommendation direction worsened across at least four AI platform families.
The label means the AI-side movement is unusual enough to merit prospective follow-up. It does not mean the company's revenue, earnings, valuation, or stock price will decline.
Read MoreP
Platform Breadth
Platform Breadth measures how many AI platform families show the same directional recommendation movement for a tracked company or entity.
Platform breadth is used as a separate signal-quality dimension because aggregate recommendation change can hide disagreement among AI systems. Broader directional participation may make an observed AI-side movement more robust, but it does not by itself establish commercial or financial predictive value.
Read MorePlatform Concentration Risk
Platform Concentration Risk, in the LLM Authority Index AI-search framework, is the risk that an aggregate recommendation or visibility signal depends heavily on one or a small number of AI platform families.
A company can show strong aggregate improvement even when most platforms are flat or declining if one platform moves sharply enough. Platform concentration risk therefore helps distinguish broad multi-platform movement from platform-specific movement. It is a measurement-quality concept, not a claim about the company's financial risk.
Read MorePlatform Visibility
Platform Visibility compares how the brand performs across individual AI systems such as ChatGPT, Gemini, Copilot, and Google AI surfaces.
The methodology explicitly separates datasets by platform because the same brand can perform differently across LLM environments. Each platform has its own retrieval patterns, answer structures, and citation tendencies, so a brand may win on one system and disappear on another. It is included because "AI visibility" is not one market; it is a set of overlapping but distinct discovery environments.
Platform Volatility
Platform Volatility measures how much performance changes across AI platforms or across reporting periods.
Because AI systems evolve quickly, visibility and recommendation behavior can shift by platform and by month. Tracking volatility helps analysts avoid overinterpreting one-off wins or losses. It is included because a durable opportunity is more valuable than a temporary fluctuation caused by platform instability.
Positive AI Divergence Candidate
A Positive AI Divergence Candidate is a V0 research classification for a company whose AI recommendation coverage increased by at least 5 percentage points, whose exploratory interval remained above zero, and whose recommendation direction improved across at least four AI platform families.
The label means the AI-side movement is unusual enough to merit prospective follow-up. It does not mean the company's revenue, earnings, valuation, or stock price will increase.
Read MorePresence Rate / Presence Coverage
Presence Rate, also called Presence Coverage, is the percentage of eligible AI observations in which a company, brand, or tracked entity appears at all, regardless of whether it is recommended.
Presence is a visibility measure rather than an endorsement measure. A company may be mentioned as background context, compared with competitors, described negatively, or listed without being recommended. Presence should therefore be interpreted separately from recommendation coverage, recommendation share, rank, sentiment, and citation behavior.
Read MorePrompt Coverage
Prompt Coverage measures which relevant user prompts the brand appears in and which it misses.
The reports are built around the idea that not all prompts matter equally; what matters is coverage across high-intent questions that align with buying, comparing, trusting, or shortlisting. Prompt Coverage therefore shows where the brand is active and where it is absent across actual demand. It is included because brands often discover that their AI visibility is patchy: strong in some buyer questions and nonexistent in others.
Prompt Subtype Classification
Prompt subtype classification breaks a cluster into narrower prompt patterns or subtopics.
Within a larger cluster like "trust" or "comparison," prompts can still behave differently depending on wording, user need, or category angle. Classifying subtypes helps isolate which exact conversations the brand wins or loses. It is included because broad clusters can hide important nuances that matter for strategy and content intervention.
Q
Query Intent
Query Intent describes what the user is trying to achieve with a prompt, such as learning, comparing, pricing, trusting, or selecting.
Intent classification helps keep the report commercially grounded. It explains why some prompts are informational, some are evaluative, and some are directly transactional in nature. It is included because the report's usefulness depends on distinguishing curiosity from buying behavior.
Query Volume (Q)
Query Volume measures how often the tracked prompts or prompt themes are searched or asked.
In the economics model, not all prompts are equally valuable; some represent much larger pools of demand than others. Query Volume is included because a brand winning a low-volume prompt cluster is less meaningful than winning a high-volume cluster with strong buyer intent. It helps weight visibility by actual market demand.
R
Recommendation Portability
Recommendation Portability describes how consistently a company's recommendation movement transfers across different AI platform families.
If recommendation coverage moves in the same direction across most major AI systems, the movement is more portable. If aggregate movement is driven by only one or two platforms while others disagree, portability is lower. Recommendation portability measures cross-platform consistency, not financial strength or predictive validity.
Read MoreS
Search Volume
Search Volume is the estimated number of searches associated with a keyword or query set.
Search Volume is often used as an input into cluster weighting and economics modeling because it helps quantify the size of the opportunity behind specific themes. It is included because the report aims to focus on real demand, not just arbitrary prompt samples.
Sentiment
Sentiment measures whether the AI's description of a brand is positive, neutral, or negative in context.
The methodology treats sentiment as contextual rather than simplistic. It considers the user question, the wording used by the AI, and the role the company plays in the answer. This is included because a brand can be visible but framed negatively, qualified cautiously, or treated as a weaker option. Visibility without favorable sentiment may not translate into trust or conversion.
Sentiment Score / Net Sentiment
Sentiment Score and Net Sentiment summarize the balance of positive, neutral, and negative brand framing across prompts.
Rather than looking only at raw counts, these summary measures provide a quicker way to compare how a brand is being described across clusters or platforms. They are included because analysts need a compact read on whether brand framing is improving, deteriorating, or holding steady over time.
T
Target Company Absence Prompt
A target company absence prompt is a prompt where competitors appear but the target company does not.
These are some of the most actionable records in the report because they represent live discovery losses. They show the exact moments where the market is having a conversation and the target brand is excluded from it. They are included because absence is often more strategically revealing than weak presence.
Top-1 Rate
Top-1 Rate is the percentage of prompts where the brand is ranked first in the AI answer.
This is the clearest measure of recommendation leadership. It shows how often the brand is the default, primary, or "best" answer rather than just one option among many. The value of Top-1 Rate is that it captures who is truly winning the buying moment. It is included because many brands are visible but rarely win the top slot, which creates a structural disadvantage that basic visibility metrics can hide.
Top-10 Rate
Top-10 Rate tracks how often a brand appears in the first ten ranked positions of an AI response.
This metric extends the ranking lens further down the answer to show whether a company is broadly present in ranked results even when it is not near the top. It is most useful for large comparison-style prompts where more brands appear. It is included because it helps distinguish total invisibility from weak-but-real inclusion and supports the ranking score logic used in Stage 0 extraction.
Top-3 Rate
Top-3 Rate measures how often a brand appears among the first three recommended companies in an AI answer.
This is a practical conversion metric because many users focus on the first few options in a list. A brand that consistently lands in the top three is still meaningfully in the consideration set, even if it is not always first. It is included because it provides a more forgiving but still commercially useful measure of competitiveness than Top-1 alone, especially in crowded categories where the brand may not dominate but still earns serious evaluation.
U
Undercontested Opportunity
An Undercontested Opportunity is a prompt area or discovery segment where the target company could gain visibility with relatively less competitive resistance.
These are the openings the report is meant to surface: clusters, platforms, or citation environments where the target is not yet strong but where recoverability or upside looks favorable. It is included because the report is not just diagnostic; it is supposed to show where gains are most realistic and commercially meaningful.
V
Value per Query (VPQ)
Value per Query estimates the economic value associated with a given query or query class.
VPQ usually comes from affiliate economics, monetization benchmarks, CPC proxies, or similar commercial inputs. It translates demand into value instead of treating all queries equally. It is included because some prompt categories are much more monetizable than others, and the report's economics layer depends on reflecting that uneven value distribution.
W
Weighted Commercial Score
Weighted Commercial Score is a blended metric used to reflect the relative business value of a cluster or prompt set.
The automation specification includes this to prevent all clusters from being treated as equally important. By combining demand and commercial signals, the report can prioritize discovery areas that likely matter more to revenue or lead generation. It is included because strategic recommendations should be guided by opportunity size, not only by visibility weakness.
