Android App Bundle (AAB)Google's modern Android distribution format that lets the Play Store generate device-optimized APKs from a single uploaded bundle — reducing average install size by 15-50%.App Clip (iOS)A lightweight version of an iOS app — up to 10MB — that launches instantly from QR codes, links, or NFC tags without requiring a full App Store install.App IconThe square graphic that represents your app across the App Store, Google Play, search results, the home screen, and notifications. The single highest-leverage ASO asset.App LocalizationAdapting the app and its store listing — text, screenshots, preview video, in-app content — to a specific language and culture for a target market.App Preview VideoA short video (15-30 seconds on iOS, up to 30s on Google Play) that demonstrates the app in action, autoplaying on the product page. The most under-used CVR asset.App SizeThe download and on-device footprint of an app. Larger sizes reduce install conversion — through cellular-download warnings, storage friction, and longer waits.App Store ConnectApple's web portal where developers submit, configure, and manage their iOS apps — metadata, builds, pricing, TestFlight, in-app purchases, and App Analytics all live here.App Store FeaturedEditorial promotion of an app by Apple's App Store editorial team — placement in the Today Tab, Apps Tab features, or category landing pages drives massive install volume.App Store Optimization (ASO)The practice of improving an app's visibility and conversion on the App Store and Google Play by optimizing metadata, keywords, creatives, and reviews.App Title / App NameThe primary name of your app shown on the App Store (up to 30 characters on iOS) and Google Play (up to 50 characters) — the single most keyword-weighted metadata field.Apple Search Ads (ASA)Apple's ad platform for promoting apps in App Store search results and other App Store placements. The highest-intent paid acquisition channel on iOS.ASO AuditA systematic review of an app's App Store / Google Play presence — metadata, creatives, keyword rankings, conversion, ratings, competitor positioning — to identify the biggest improvement opportunities.ASO ToolsSoftware platforms that provide keyword research, rank tracking, competitive intelligence, and A/B testing capabilities for App Store and Google Play optimization.Bundle IDThe unique reverse-DNS identifier for an app (for example com.company.app) that the operating system and app stores use to distinguish it — fixed once the app is published.Conversion Rate (Product Page CVR)The percentage of users who visit your App Store / Google Play product page and proceed to install. The CVR multiplier on every traffic source you have.Conversion Rate Optimization (CRO)The systematic practice of improving the percentage of users who complete a defined action — typically browse-to-install on the App Store / Google Play product page.Custom Product Page (iOS)An iOS App Store feature that lets you publish up to 35 alternate product-page variants — each with its own screenshots, preview video, and promotional text — addressable by a unique URL.Dynamic Island (iOS)A persistent interactive status surface at the top of compatible iPhone screens that displays Live Activities, notifications, and system status — introduced with iPhone 14 Pro (2022).Hybrid AppAn app built with web technologies (HTML, CSS, JavaScript) wrapped in a native shell, running on iOS and Android from a single codebase — a middle ground between fully native and pure web apps.Icon A/B TestingThe practice of systematically testing alternate app icon variants to find the one that drives the highest browse-to-install conversion.In-App Events (iOS)Time-bound events promoted directly on the iOS App Store — sales, content drops, tournaments, major updates — that appear as cards on your product page and in search results.Instant AppsA Google Play feature that lets users run part of an app instantly — without a full install — to try it before committing, reducing the friction between discovery and first experience.iOS WidgetA glanceable home-screen surface for an iOS app — displays info from the app without requiring the user to open it. Available since iOS 14 (2020); interactive widgets since iOS 17 (2023).Keyword CannibalizationWhen two of your own apps (or two pages of your own site) compete for the same keyword — splitting the algorithm signal between them and weakening both rankings.Keyword DifficultyA score (typically 0-10 or 0-100) estimating how hard it is to rank in the top results for a given App Store search term, based on the strength of the apps that currently occupy those positions.Keyword RankingThe position your app holds in App Store / Google Play search results for a specific keyword in a specific country — the atomic unit of ASO measurement.Keywords Field (iOS)A 100-character comma-separated iOS field that is indexed for App Store search but never shown to users — a core ASO keyword surface.Live Activity (iOS)An iOS framework (since iOS 16.1) that lets apps display live-updating content on the lock screen and Dynamic Island — sports scores, food delivery, ride-share, timer countdowns.Pre-RegistrationA pre-launch mechanism where users sign up to install your app before launch — they're notified when the app goes live and the install proceeds automatically.Promotional TextA 170-character iOS field visible at the top of your App Store listing that can be updated without an app review — useful for time-limited offers and announcements.Review Response StrategyThe practice of systematically responding to app store reviews — particularly negative ones — to recover the original rating, retain the user, and signal active development to the algorithm.ScreenshotsThe images shown on your product page on the App Store and Google Play — the single biggest driver of browse-to-install conversion rate.Short Description (Google Play)The 80-character text snippet shown in Google Play search results and at the top of the listing — the second-most-important text field for Google Play ASO after the app title.Staged Rollout (Google Play)A Google Play release mechanism that ships a new app version to a configurable percentage of users (1% → 5% → 20% → 100%) — limiting exposure to bugs and letting developers monitor crash rates before full rollout.Store Experiments (Google Play A/B Testing)Google Play's native A/B testing platform for store-listing assets — icon, screenshots, short description, feature graphic, promo video. iOS has no direct equivalent.Subtitle (iOS)A 30-character field on the iOS App Store that sits beneath the app name — second only to the title in keyword weight.TestFlightApple's official platform for distributing pre-release iOS app builds to beta testers — supporting up to 10,000 external testers per app, with separate internal testing for the dev team.
