Discoverability surfaces
An LLM trained to use extended chain-of-thought as a native capability rather than as a prompting technique. The model invests compute time at inference (sometimes minutes) to work through problems step-by-step before answering. OpenAI's o1/o3, Anthropic's Claude with extended thinking, and DeepSeek's R1 are the headline examples. Reasoning models tradeoff latency for accuracy on hard problems — best-fit for math, code, scientific reasoning, and complex planning tasks.
Programmatic SEO, AEO, GEO, AIO, and the schemas behind them.
A content strategy that generates hundreds or thousands of search-optimized pages from structured data using templates.
The practice of structuring website content so that AI assistants and large language models (LLMs) can accurately cite it when answering user questions.
An open protocol that allows websites to notify search engines (Bing, Yandex, Seznam, Naver, and others) about new or updated content in real time.
Structuring content so that answer engines — Google's People-Also-Ask, Reddit pull-quotes, Quora top answers, ChatGPT search results, Perplexity citations — can extract a complete, self-contained answer in 40–80 words.
The subset of GEO/AEO targeted specifically at Google's AI Overviews (formerly SGE).
