Quick answer: Improve your Steam review score by fixing the recurring problems behind negative reviews (frequently a specific crash or bug) and responding to those reviews when you fix the issue. Steam weights recent reviews and lets players edit them, so resolving the ongoing cause and replying that it's fixed lifts the recent score as players revise, a real, repeatable recovery path.
Your Steam review score heavily affects discovery and sales, and it's something you can deliberately improve, especially the recent-reviews score, which Steam weights and which reflects how the game is now. Improving it is mostly about resolving the specific problems driving negative reviews and using Steam's mechanics (recent weighting, editable reviews) to your advantage.
Negative Reviews Usually Have a Specific, Fixable Cause
Most negative reviews aren't a vague 'this game is bad', they're 'this specific thing ruined it for me,' and that thing is often a fixable problem, frequently a crash, a serious bug, or poor performance. Players who hit a bug and couldn't easily report it often leave a negative review instead, so the reviews are effectively bug reports. Reading them for the recurring complaint reveals what's dragging your score down.
Correlating the review complaints with your crash and bug data sharpens this: a spike in negative reviews often lines up with a spike in occurrences of one issue. Bugnet's crash and bug reporting with occurrence data helps connect the reviews to the specific issues behind them, so you fix causes, not vague impressions.
Fix the Recurring Problem
A continuously poor or falling score usually means a recurring problem keeps affecting new players, each generating another negative review. As long as it persists, the negative reviews keep coming. So the core move is to fix the recurring issue, the high-occurrence crash or bug driving the complaints, which stops the bleeding at the source.
Prioritize the issues with the most impact (and the most review correlation), and fix them. Once new players stop hitting the problem, the flow of negative reviews about it stops, and the score can start recovering as positive reviews accumulate.
Respond and Let Recent Reviews Carry the Recovery
Steam weights recent reviews and lets players edit them, which makes review-driven problems uniquely recoverable. When you fix the bug behind a negative review, respond to it, 'this is fixed in the latest update, sorry it hit you', and many players revise their rating once their actual problem is solved. A run of fixes plus responses can visibly lift your recent-reviews score.
Track which reviews map to which fixed issues so you can circle back when the fix ships. Improving your Steam review score is the combination, fix the recurring problems driving negative reviews (found by correlating reviews with your crash/bug data), respond when you fix them, and let Steam's recent-review weighting carry the recovery, that turns a poor score into an improving one.

Negative reviews usually name a fixable problem, often a crash or bug. Fix the recurring issue (correlate reviews with crash data), respond when you do, and Steam's recent-review weighting carries the recovery.
