Straight definitions for the terminology behind AI content, AEO, and GEO.
AI Humanization is the process of rewriting AI-generated text to reduce detectable machine patterns, so it reads naturally and scores low on AI-detection tools like GPTZero and Originality.ai, while preserving the original meaning and facts.

The AI Detection Score is a percentage estimate, produced by tools like GPTZero, Originality.ai, or a built-in checker, of how likely a piece of text is to have been written by an AI rather than a human. Lower scores indicate text that reads as more human-written.

Answer Engine Optimization (AEO) is the practice of structuring content, such as direct definitions, clear headings, and Q&A formats, so that answer engines like Google featured snippets, Siri, and Alexa can extract and surface it directly as an answer.
Related: Generative Engine Optimization (GEO), Zero-Click Search
Generative Engine Optimization (GEO) is the practice of structuring and writing content so that generative AI systems, such as ChatGPT, Perplexity, and Google AI Overviews, are more likely to cite or quote it when generating answers to user queries.

Perplexity RAG refers to the retrieval-augmented generation pipeline Perplexity.ai uses to answer queries: it retrieves relevant live web pages, then generates an answer grounded in and citing those sources, rather than relying only on the model’s training data.

Content velocity is the rate at which a website publishes new content over a given period. Higher, sustained content velocity is associated with faster indexing and more topical coverage, but only when quality is maintained alongside output.

E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is a framework from Google’s Search Quality Rater Guidelines used to evaluate content and site quality, especially for topics that affect a reader’s health, finances, or safety.

A zero-click search is a search query that gets answered directly on the search results page, via a featured snippet, knowledge panel, or AI Overview, so the user never clicks through to a website.
