License content for AI citation by publishing an explicit license that permits quoted citation with attribution and prohibits wholesale republication — the goal is to make it legally safe for models to quote you while keeping copyright leverage against sites that copy the full text.
Two extremes fail. Choosing "all rights reserved" makes it legally ambiguous whether an AI system may quote even a short passage, which some engines interpret as a signal to avoid the source. Choosing an unrestricted permissive license like Creative Commons CC0 lets scrapers rebuild your entire content library on their own domains at no legal risk.
A middle-ground approach is a custom "citation license" — attribution required, short quotes welcome, wholesale republication prohibited. The Citation License 1.0 is one example of that pattern; publishers can adopt or adapt it.
Whatever license you choose, make it discoverable. Publish it at a stable URL, link to it from the footer, reference it in the JSON-LD CreativeWork license field, and stamp it into the provenance footer of any markdown twin or bulk export. Explicit licenses make the "may I quote?" question a lookup, not a guess.
Combine the license with robots.txt policy on training crawlers (e.g. GPTBot, Google-Extended, ClaudeBot). Legal terms and technical controls together produce a coherent stance.
