Show the prompt when the user expects or benefits from notifications, not on first visit or during low-focus moments. Ask after a helpful action so the permission feels like a natural next step. Tie the wording to context so users see value immediately. Delay prompts when users are engaged in reading or interacting; use subtle in-app reminders instead. Respect repeat denials by offering a clear, easy path to enable later from settings. Finally, A/B test timing and phrasing across user segments to find when acceptance spikes.
