Number of ratings & average score is one of the most important aspect to get someone to download your app. A high average score (4.5+) builds a trust and makes people comfortable to become paying customers.
With Taskito, it's always my aim to get more & more reviews as it helps with organic growth. Here are a few tips to get more reviews and improve the average score.
Prompt users to give a rating when they have finished a happy path. Use Google Play in app review to make it seamless.
Whenever you interact with one of the users, ask them to leave a review. Add it in your email signature, chat auto messages.
If they give your app app 3 or 4 star rating, reply to them and politely ask them to improve the rating. More users will change their review if you reply to them.
