How to minimize the number of deleted reviews?

There is no perfect and guaranteed way to do it, but you can reduce the percentage of deleted reviews by following these simple recommendations: 

1. Do not order reviews amounting to more than 2-3% of the number of installations per day for the selected country (more details). 
2. Try to respond instantly to new reviews left on behalf of the developer account. 
3. ‘Like’ the new positive reviews from your device and the devices of your colleagues.
