Shopping where an AI agent discovers, compares, and buys products on a person's behalf. Moving the buying decision from human browsing to machine selection.
AI search termAgentic Commerce Protocol (ACP / UCP)
Open standards that let AI agents complete a purchase. Exposing product, price, and checkout data in a machine-readable way. Examples: ACP (OpenAI + Stripe) and Google's UCP.

An automated bot that fetches web pages for an AI company. To train a model, build a search index, or pull a page live to answer a question.
AI search termAI Hallucination
When an AI generates plausible-sounding but false information. Including wrong facts about a brand, invented features, or fake citations.
AI search termAI Overviews
Google's AI-generated answer summaries that appear above traditional search results, synthesising and citing sources for a query.
BuffyAI Visibility Score
A composite 0-100 score blending share of voice, top-ranked %, average rank, and citation coverage into one headline read of how visible your brand is across AI answers.
AI search termAI-Readiness Audit
A structured check of whether AI engines can reach, read, understand, corroborate, and quote your site. Grading crawler access, extractability, product data, off-site presence, and quotability, usually as scored pillars.
AI search termAnswer Engine Optimization (AEO)
Optimizing your content to become the cited source when AI answer engines generate a direct response to a question.
AI search termAnswer Volatility
How much an AI engine's answer. The brands it names and the sources it cites. Changes when the same or a slightly reworded question is asked again.
AI search termAstroturfing
Manufacturing fake grassroots endorsement. Using coordinated fake accounts, planted posts, or paid engagement to make brand promotion look like organic community consensus.
BuffyAverage Rank
Your brand's average position in AI-recommended lists across prompts where it's mentioned. Lower is better. #1 means consistently first.
BuffyBrand Perception
A qualitative read of how AI platforms collectively describe and position your brand, based on branded queries.
AI search termCitation (AI / LLM)
When an AI answer references and links a source it used. Being cited (not just mentioned) is how you earn trust and AI-referred traffic.
BuffyCitation Coverage
Of the AI answers that mention your brand, the share that also cite your brand's own website as a source.
AI search termCitation Gap (Source Gap)
The difference between the sources AI engines cite for your category and the ones that mention you. Revealing where you're absent from the answer.
AI search termCitation Hallucination
When an AI produces a reference that looks legitimate but fails at the level of identity. Either the cited work doesn't exist, or a real work is credited to substantially the wrong authors.
BuffyCited Pages
The unique URLs AI cites as sources when mentioning your brand.
AI search termCommodity Content
Content that restates what many pages already cover without adding first-hand experience or unique knowledge, making it easily replaceable and increasingly hard to get indexed or cited.
AI search termContent Decay (Citation Cliff)
The decline in how often AI engines cite a page as it ages. Live retrieval favors recently-updated content, so citations fall off after roughly a quarter.
AI search termConversational Search
Searching by asking full, natural-language questions. Often in a back-and-forth. Instead of typing keywords, the way people use ChatGPT, AI Mode, and Perplexity.
AI search termCorroboration
Multiple independent, credible sources agreeing on the same fact. A strong signal that makes AI engines more willing to state and cite it.
AI search termDark Library Effect
The gap between how heavily AI crawls and cites a page and how little referral traffic it sends back. Most visible on articles, which AI reads and summarises but rarely links a visitor to.
AI search termDark Traffic
Real visits whose true source is invisible to analytics. They arrive with no referrer and get filed as 'Direct,' hiding much of your AI-driven traffic.
AI search termE-E-A-T
Google's quality framework. Experience, Expertise, Authoritativeness, Trustworthiness. Signals that also shape whether AI engines treat your content as a credible source.
AI search termEarned Media
Coverage and mentions a brand earns from independent third parties. Press, reviews, forums, and best-of lists. Rather than pays for (paid media) or publishes itself (owned media). It is the dominant source of AI citations.
AI search termEmbeddings
Numeric representations of meaning that let an AI judge how related two pieces of text are. The basis of semantic search and retrieval.
AI search termEntity Authority
How strongly and credibly AI associates your brand with a topic. A strong predictor of AI citations, often more than backlinks or technical SEO.

AI search termGenerative Engine Optimization (GEO)
The practice of getting your brand mentioned, cited, and recommended across generative AI engines like ChatGPT, Gemini, and Claude.
AI search termGhost Citation
When an AI answer uses your page as a source and links it, but never names your brand in the text. A citation with no mention attached.
AI search termGoogle AI Mode
Google's conversational, AI-generated search experience. A full chat interface powered by Gemini, distinct from the shorter AI Overview summary.
AI search termGrounding
Connecting an AI's answer to verifiable external sources, so claims are backed by retrieved evidence rather than the model's memory.
BuffyHero Products
Your flagship products. Each gets a dedicated deep-dive prompt and is scored individually for how favourably AI describes it.
AI search termKnowledge Cutoff
The date after which a model's training data stops, so without live search, it doesn't 'know' anything more recent.
AI search termKnowledge Graph
A structured map of real-world entities. Brands, products, people, and the relationships between them, used by search and AI engines to 'know' what your brand is.
AI search termLarge Language Model (LLM)
An AI model trained on vast amounts of text that predicts and generates language. The engine behind ChatGPT, Gemini, Claude, and AI search.
AI search termllms.txt
A proposed standard. A Markdown file at /llms.txt, that gives AI crawlers a concise, curated guide to your site's most important content.
AI search termMultimodal Search
Searching with images or voice, not just typed text. A fast-growing share of AI queries, where the engine interprets a photo or spoken question.
AI search termProduct Feed
A structured file of your products, one row per item with attributes like title, price, availability, and GTIN, that feeds shopping and AI systems the facts they surface.
AI search termPrompt
The question or instruction a person gives an AI. The AI-search equivalent of a search query, but usually longer and more conversational.
AI search termPrompt Injection
Trying to manipulate an AI's output by feeding it crafted text. Including attempts to plant fake rankings or claims a model might repeat.
AI search termQuery Fan-Out
When an AI decomposes one user question into several parallel sub-searches, then synthesises the results, so a single prompt pulls from many sources.
AI search termRetrieval-Augmented Generation (RAG)
An architecture that pairs a language model with live document retrieval, so answers are grounded in fetched sources rather than memory alone.
AI search termrobots.txt
A file at your domain root that tells crawlers. Including AI bots, which pages they may or may not fetch.
AI search termSemantic Search
Retrieval based on meaning rather than exact keywords. Matching the intent behind a query to content that answers it, using embeddings.
AI search termSentiment Analysis
Measuring not just whether a brand is mentioned in AI answers, but how it's described. Positive, negative, or neutral.
BuffyShare of Voice (SoV)
The percentage of AI answers to category prompts that mention your brand at all.

AI search termSilent Source
A page an AI engine reads and uses during retrieval to shape its answer, but never links or names in the final response. It informs the answer invisibly.
AI search termSite Reputation Abuse
Publishing third-party content on an established, trusted site mainly to exploit that site's ranking and citation signals. A named Google spam tactic, sometimes called parasite SEO.
AI search termStablecoin
A cryptocurrency token designed to hold a stable value by being pegged to a reserve asset. Usually the US dollar, so it can be used for payment rather than speculation.
AI search termStructured Data (Schema markup)
Machine-readable Schema.org markup (Product, FAQ, Organization, etc.) that labels what your content is, making it far easier for AI to parse and cite.
BuffyTop-Ranked %
Of the AI answers that mention your brand, the share that rank it #1. The single top pick.
BuffyTotal Mentions
The total number of times your brand was mentioned across all tracked prompts in the latest analysis.
AI search termWeb Discovery Project
