How to promote a review to the 1st place/page on Google Play?

Question

Android

It has been repeatedly observed that some users (and more often competitors) manage to "move" a review to the 1st place on the page of any application (in this case, we are talking about free applications), in which they advertise their brand and thereby squeeze out relevant traffic from competitors' application pages. The review is in the first place as if rooted to the spot, for 4-6+ months, even considering that a huge number of other "positive ones" have already been left after it! reviews (more than 10 thousand new ones).
The question is, what factors influence the ranking of a review on Google Play and how can you raise your review to the first place?

Answer 1

Reviews are sorted on Google Play. Take a closer look at the review panel. By default, they are sorted by their usefulness. So, as dug in the first place is the most useful review.
The question is how to make this review the most unsurpassedly useful. The answer is also simple.
At their core, both points describe botnets. In the first case, the bot-no will consist of living people, and in the second - of infected machines. The purpose of these botnets is the same: promotion or retention of the product/review in the desired position.
A lot of the current top products on the GP/AppStore are promoted using one or both of these methods. Moreover, initially such services were provided only in relation to the Apple store. And only relatively recently, the cancer spread to Android.
