Acquisition (store listing acquisition)
Users who installed after visiting your Google Play listing. Play Console reports it by traffic source and country. It is the main outcome ASO tries to grow.
Android vitals
Google Play's technical quality metrics, such as user-perceived crash rate and ANR (App Not Responding) rate. Google says apps above its bad-behaviour thresholds can get less visibility on Google Play.
app-ads.txt
A public text file on a developer's website that lists the ad networks and seller accounts authorised to sell that developer's ad inventory. It helps prevent ad fraud, and for competitor research it reveals which ad networks an app works with. More in the competitor guide.
ASO (app store optimization)
Improving an app's store listing so it ranks for relevant searches and converts more visitors into installs. See the full Google Play ASO guide.
Category
The Google Play section an app is filed under (for example Music & Audio). It determines which charts you appear in and who you are compared with.
Content rating
The age rating (such as "Rated for 12+") assigned through the IARC questionnaire in Play Console. It affects who can see and install the app.
Conversion rate
The share of listing visitors who install. Icon, screenshots, rating and the short description drive it, and it feeds back into ranking.
Custom store listing
An alternative version of your listing shown to a chosen audience, such as users in specific countries or visitors from a specific link. It is useful for localized messaging.
Data safety section
The part of a Google Play listing where the developer declares what user data the app collects and shares. It is public and worth comparing across competitors.
Developer page
The Google Play page that lists all live apps from one developer account. Analysing it shows a competitor's whole portfolio and strategy.
Feature graphic
A 1024×500 image shown at the top of a listing when there is a promo video, and in some featured placements.
Full description
The long "About this app" text, up to 4,000 characters. Google Play indexes it for search, so it should cover your keyword themes naturally.
In-app purchase (IAP)
Digital items or subscriptions sold inside an app. Google Play lists whether an app offers them and a price range per item.
In-App Review API
Google Play's official way to ask for a rating inside an app without sending the user to the store. Google applies a quota, so the dialog does not always appear. How to use it well.
Install tier
The rounded install count Google Play shows publicly, such as 100K+, 1M+ or 1B+. Exact installs are only visible to the developer in Play Console.
Keyword density
How often a word or phrase appears in a text relative to its length. On Google Play it helps you spot missing or overused phrases. It is a diagnostic, not a target.
Keyword research
Finding and choosing the phrases your listing should target, based on relevance, demand and competition. Step-by-step guide.
Keyword stuffing
Repeating keywords unnaturally or listing unrelated terms to game search. It violates Google Play's metadata policy and can get updates rejected.
Localization
Adapting the listing (text, screenshots, sometimes keywords) and the app for each language and market. Keyword research should be redone per language, not translated.
Long-tail keyword
A longer, more specific search phrase (for example "expense tracker for couples"). Each one has less traffic but less competition, which makes them the best targets for new apps.
Market (storefront)
A country version of Google Play, with its own search results, charts and availability. The Country Availability Checker scans 141 of them.
Metadata
The text and assets of a listing: title, descriptions, icon, screenshots, video, category and contact details.
Package name
The unique app ID, such as com.spotify.music. It appears in the listing URL and cannot change after publishing.
Permissions
The device capabilities an app asks for (camera, location, contacts). Asking for more than similar apps can lower trust and conversion.
Promo video
A YouTube video linked from the listing that plays above the screenshots. It should show the app in use within the first few seconds.
Rating
The average star score shown on the listing. Google Play weights recent ratings and shows scores per country and device type.
Review gating
Asking users whether they like the app and only sending happy ones to rate. It is not allowed under Google Play's In-App Review guidelines.
Screenshots
The images on a listing. The first two or three do most of the conversion work, so they should show the core benefit.
Search visibility
How often and how high an app appears in Google Play search for relevant keywords.
Short description
The 80-character summary shown near the top of a listing. It is important for conversion and is indexed for search.
Store listing experiment
A Play Console A/B test that shows different icons, screenshots or text to different visitors and reports which one gets more installs.
Title (app name)
The app name on Google Play, up to 30 characters. It carries the most keyword weight, so it usually combines the brand with the main keyword.
