Keyword strategy in app stores works differently than the open web
App store search algorithms weigh title, subtitle, and keyword fields differently than a typical web page, and the competitive landscape is entirely different since you are only competing against other apps, not the whole web.
Conversion rate on the store listing page is its own optimization problem
Screenshots, preview video, and description copy all affect whether someone who finds an app actually installs it, independent of how well the app ranks for a given search term. A high-ranking listing with a weak conversion rate still underperforms.
Paid user acquisition and organic ASO should inform each other
Apple Search Ads and Google Play campaign data reveal which search terms actually convert to installs, which is genuinely useful signal for prioritizing organic ASO keyword work, rather than treating the two as unrelated efforts.
