SearchShifter™ Glossary

Definitions of key terms for AI visibility and Generative Engine Optimization (GEO). This glossary provides context and clarity for structured answers, schema, hidden signals, and other elements that improve your website’s visibility inside AI engines.

AI Visibility

The ability of your content, brand, or website to be discovered and quoted inside artificial intelligence tools such as ChatGPT, Gemini, Claude, and Perplexity. Unlike traditional SEO, which focuses on Google rankings, AI visibility focuses on appearing in AI-generated answers.

Generative Engine Optimization (GEO)

The practice of structuring your website so that AI engines can interpret and quote it. GEO includes Q&A blocks, schema, glossary links, hidden signals, and llms.txt to help AI tools trust and recommend your content.

Hidden Signals

Metadata and structural elements such as canonical tags, last updated dates, author attribution, and breadcrumbs. These signals are not always visible to users but are essential for AI engines to validate authority.

Schema

Structured data markup (JSON-LD) that helps search engines and AI engines understand your content. Examples include FAQPage schema for Q&A sections and DefinedTerm schema for glossary entries.

Large Language Models (LLMs)

A crawler instruction file similar to robots.txt but designed for large language models (LLMs). It provides AI crawlers with guidance about which parts of your site can be used for training and citation.
