Read scope first
Training use, summaries, previews, and country rules differ.

Publishers with ad revenue

Brand sites may still want selective presence.
Document decisions
What you toggled, when, expected impact.
Revisit quarterly.
Opt-out rules are permissions management, not bravery. Treat them like contracts with tradeoffs, not like a moral badge.
