Apple Guideline 2.3.7 and Google Play's Spam and Minimum Functionality keyword-spam policy both result in rejection when competitor names or stuffed keywords are detected. On the App Store, the 100-character keyword field is machine-parsed; exceeding it causes an automatic metadata validation failure before a human reviewer sees your app. On Google Play, keyword stuffing in the description triggers algorithmic suppression — your app ranks lower for every keyword it over-repeats, precisely the opposite of the intended effect. Using a competitor's trademark ('Spotify', 'Headspace') as a keyword additionally exposes the developer to trademark infringement claims under Lanham Act theories.
High because keyword violations cause automatic submission rejection on App Store and algorithmic ranking suppression on Google Play, directly blocking discoverability.
Audit fastlane/metadata/ios/<locale>/keywords.txt before every submission. The entire field must be 100 characters or fewer — verify with:
wc -c fastlane/metadata/ios/en-US/keywords.txt
Remove every competitor name. Remove your app's own name (App Store indexes it automatically). Remove any keyword repeated more than once. Replace stuffed repetitions with distinct, high-intent terms your actual users search for. Keep keywords.txt version-controlled in fastlane/metadata/ so keyword changes are reviewable in git history before submission.

Check for: (a) competitor app names (e.g., "Spotify", "Netflix", "Instagram", "Duolingo", "Headspace") — using competitor names as keywords is a policy violation on both platforms, (b) keyword stuffing — repeating the same word multiple times in the keywords field (e.g., "meditation, meditation app, meditation timer, best meditation"), (c) the app's own name repeated in the keywords field (App Store ignores app name in search automatically), (d) irrelevant category keywords (a flashlight app listing "social media, dating, games" as keywords), (e) exceeding platform character limits (App Store: 100 characters total including commas). For Google Play, check whether the short description and full description over-repeat keywords — Google's algorithm penalizes obvious stuffing. Before evaluating, extract and quote the keywords field or keyword-dense sections of the description to assess repetition patterns.
