About this skill

About App Store listing optimizer

App store listings have very few characters, and most apps waste them. This skill picks high-intent keyword themes from your features and competitors, then writes the App Store title, subtitle and 100-character keyword field and the Google Play title and short description, showing the character count of each. It avoids repeating words across App Store fields, which wastes indexing space, and never uses competitor brand names. It also drafts the first lines of the full description and screenshot captions, the parts users read before deciding to install. To use it, paste the skill into your assistant and send your app's purpose, main features, competitors and the store (App Store, Google Play or both).
