Google appears to be getting stricter about apps on Google Play Store. The company has announced that it has now got an algorithm that will downgrade apps with bad reviews.
According to the search giant, "As part of our continued effort to deliver the best possible Google Play experience, we recently enhanced our search and discovery algorithms to reflect app quality." It added, "This results in higher quality apps being surfaced in the Play Store more than similar apps of lower quality (eg: apps that exhibit more frequent crashes)."
