Glossary · 22 terms

The AI marketing glossary.

Plain-English definitions of every term you need to operate in AI search in 2026. AEO, GEO, AAAT, knowledge graph, citation rate, llms.txt, and the 16 other concepts that decide whether ChatGPT, Perplexity, Claude, and Gemini cite your brand or your competitor.


  • AEO — meaning and why it matters

    Answer Engine Optimization. The discipline of structuring a website so AI answer engines — Google AI Overviews, Perplexity, You.com, SearchGPT — cite it as a source. AEO targets the synthesized-answer surface, not the blue-link list.

  • GEO — meaning and why it matters

    Generative Engine Optimization. The discipline of getting cited by conversational LLMs — ChatGPT, Claude, Gemini. The primary lever is off-site presence in places those models already trust (trade press, podcast transcripts, Wikipedia, GitHub READMEs).

  • AAAT — meaning and why it matters

    Agentic AI Advertising Team. The AdMax operating model — a senior human strategist plus four named AI agents (Sage, Lab, Helm, Lookout) each owning one part of the always-on side of a marketing engagement.

  • AI Overview — meaning and why it matters

    The synthesized paragraph that appears above the traditional blue links on Google for most informational queries. Generated by Gemini plus Google's retrieval system, with three to seven citation links underneath.

  • Citation rate — meaning and why it matters

    The percentage of buyer queries in a category where an AI engine cites your brand by name. The headline AEO/GEO metric.

  • llms.txt — meaning and why it matters

    A short Markdown file at the root of a domain that tells AI crawlers what the site is, who it serves, and which pages summarize the brand best. Format documented at llmstxt.org.

  • robots.txt — meaning and why it matters

    The directive file that tells crawlers which paths to read and which to skip. For AI visibility, robots.txt must explicitly allow GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and CCBot.

  • Knowledge graph — meaning and why it matters

    A machine-readable network of entities (people, places, organizations, concepts) with relationships between them. Google, Wikipedia, Wikidata, and Crunchbase maintain knowledge graphs; AI engines pull from these to anchor brand descriptions.

  • Schema markup — meaning and why it matters

    JSON-LD structured data blocks that tell engines what a page is about. Organization, Article, FAQPage, Service, HowTo, BreadcrumbList. AEO requires clean schema across every cornerstone page.

  • Cornerstone page — meaning and why it matters

    A high-priority, evergreen page that defines a key topic for the site. AdMax cornerstones include /aaat, /audit, the AEO/GEO services, and the major blog explainers.

  • Sidechain compression — meaning and why it matters

    An audio production technique where one signal (typically voice) triggers compression on another (typically music). Used in podcasts and reels to make the music duck under the voice automatically.

  • Answer-shaped content — meaning and why it matters

    Content structured as question-H2 + 40-to-80-word direct answer + supporting depth below. AI engines extract the direct answer; humans read the depth.

  • Crawl budget — meaning and why it matters

    The number of pages a search engine will crawl on a site in a given session. Higher crawl budget = faster indexing of new content. Earned by site authority and signaled by sitemaps with priority weights.

  • Sitemap — meaning and why it matters

    An XML or JSON file listing every page a site wants engines to find. Submit to Google Search Console and to Bing Webmaster Tools. Priority weights tell engines which pages matter most.

  • Canonical tag — meaning and why it matters

    An HTML tag declaring the official URL for a page. Prevents duplicate-content penalties and tells AI engines which version to cite.

  • Off-site mention — meaning and why it matters

    A reference to your brand on a site you do not control — trade press, podcast transcripts, association directories, Reddit. The trust signal that makes AI engines treat you as a citable source.

  • AI Overview citation — meaning and why it matters

    A link appearing in the citations bar underneath a Google AI Overview. The 2026 equivalent of a #1 organic ranking — pulls disproportionate click-through versus non-cited pages.

  • Indexability — meaning and why it matters

    Whether a search engine is allowed to add a page to its index. Blocked by robots.txt rules, noindex meta tags, or canonical conflicts.

  • Core Web Vitals — meaning and why it matters

    Google's three page-experience metrics — LCP (load), CLS (layout stability), INP (interaction responsiveness). All three must be green for cornerstone pages.

  • Topical authority — meaning and why it matters

    The signal that a domain is a deep expert on a subject. Built by publishing a connected cluster of cornerstone + supporting pages around a single topic. AEO engines reward topical authority strongly.

  • Hybrid agency — meaning and why it matters

    A marketing agency that pairs senior human strategists with AI agents. The strategist owns the plan and the relationship; the agents execute the always-on side — analytics, creative iteration, optimization, market watch. AdMax is one.

  • Pixel — meaning and why it matters

    A small piece of JavaScript embedded on a website that tracks visitor behavior. The Search Atlas dynamic-optimization pixel lets OTTO ship per-page SEO fixes without redeploying the site.
