Discoverability surfaces
Continued training of a foundation model on a smaller, task-specific dataset to specialize its behavior. Full fine-tuning updates all model weights; parameter-efficient fine-tuning (PEFT) methods like LoRA update only a small adapter layer, dramatically reducing compute cost and storage. Fine-tuning is the path for domain-specific knowledge, brand voice, or format consistency that prompting alone can't reliably achieve.
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).
