1. Never use technical tricks (e.g., custom pop-ups) to force users into leaving only positive reviews - Google detects this and treats it as a policy violation; 2. Use the In-App Review API properly - request a rating only after the user completes a positive action (e.g., finishing a level, a successful payment); 3. Reply to low-rated reviews via the Google Play Developer API - showing a proactive problem-solving attitude helps improve conversion; 4. Set up a review monitoring bot and respond to important reviews within 24 hours; 5. Never buy bulk fake reviews - Google anomaly detection will flag them and may lead to app removal.
