Quick answer: Fix the high-impact bugs and crashes that drive negative reviews, show the fixes via a changelog to prompt revisions, and prevent new bug-driven reviews by keeping the game stable, bug-driven negative reviews are preventable.
Many negative reviews are about fixable bugs, so improving your review score means fixing them. Here are the best ways to improve your review score.
Fix the High-Impact Bugs Driving Reviews
Improve your review score by fixing the high-impact bugs and crashes driving negative reviews, since each affects many players (and each review represents many silent ones), so fixing them stops new bug-driven negative reviews at the source.
Bugnet captures crashes with impact ranking, so you can identify the high-impact issues generating the most negative reviews (the ones affecting the most players) and fix them first, stopping the negativity at its source.
Show the Fixes to Prompt Revisions
Improve your review score by showing the fixes via a changelog and update notes, since players who see a bug fixed sometimes revise their negative review upward, and prospective players are reassured. Visible fixes help your score recover.
Bugnet gives you a changelog and tracker to show players the issues are fixed and which version resolved them, prompting some negative reviews to be revised and reassuring prospective players, helping your score recover.
Prevent New Bug-Driven Reviews
Improve your review score over time by preventing new bug-driven reviews, keep the game stable (monitor per version, catch regressions) so new players do not hit the issues that generate negative reviews. Stability prevents the negativity.
Bugnet tracks crashes per version with alerts, so you catch regressions and new crashes that would generate negative reviews, keeping the game stable so new bug-driven reviews do not accumulate.
