AI Overviews
The written summary Google now places above its search results, assembled from several pages and citing a few of them. Appearing inside one can bring visitors; being left out of one can quietly cost you the clicks you used to get.
Chunking
Splitting a long page into smaller passages so an AI can retrieve just the relevant part. Pages with clear headings chunk cleanly; a single unbroken wall of text does not.
AI Visibility
How often, and how accurately, AI assistants mention your business when someone asks about what you do. Unlike search rankings there is no official scoreboard, so it is measured by asking the assistants and by watching which crawlers visit.
Prompt
The instruction or question you give an AI. The wording matters more than people expect: the same request phrased two ways can produce noticeably different answers.
Recommendation Engine
A system that suggests what somebody might want next based on behaviour — the “customers also bought” of an online shop. One of the oldest commercial uses of machine learning.
Applebot-Extended
Apple’s equivalent, governing whether your content feeds Apple Intelligence. Ordinary Applebot, which powers Siri and Spotlight, is controlled separately.
