Conversion Rateとは？

Conversion rate is one of the most critical ASO metrics because it directly measures how effectively your listing persuades users to install. A high-traffic listing with a low conversion rate wastes the visibility you have worked to achieve. The average App Store conversion rate varies by category but typically falls between 20% and 40% for well-optimized listings.

Several factors influence conversion rate. Screenshots are the most impactful visual element — they occupy the largest portion of your listing and are the first thing users evaluate. The first three screenshots are especially critical since they appear in search results before a user taps into your full listing. Your app icon, ratings, and review count also play major roles. Apps with ratings below 4.0 see significantly lower conversion rates than those above 4.5.

Apple provides conversion data through App Store Connect analytics, broken down by source (search, browse, referral). Google Play Console offers similar data through store listing visitors and installers. Track your conversion rate over time, run A/B tests on visual assets, and compare your rate against category benchmarks. Even a 5% improvement in conversion rate at scale can mean thousands of additional monthly downloads.
