App Store Optimization for Games Apps: Strategy Guide

The Games Category Landscape

Games is the largest category on the App Store, with hundreds of thousands of apps from casual puzzles to multiplayer RPGs. That size cuts both ways: the audience is huge, and so is the number of games asking for the same searches. Games also lead the download and revenue charts, so ASO decides whether a new title is found at all.

How crowded a search is depends on how specific it is. A broad word like "puzzle" or "runner" matches every game that ever used it, while a phrase that names a mechanic or a theme only matches the games built around it. Knowing where your game sits on that line is the first step of a keyword strategy.

Keyword Patterns in Games

From Generic Words to Specific Phrases

Game searches come in a few shapes, and each asks something different of your metadata:

• Generic: "game", "free game", "offline game", "puzzle game". Every game wants these, so they are the first place to check how strong the top results are before you spend characters on them.
• Genre: "word puzzle", "block puzzle", "idle game". Worth a place in your title or subtitle when your game fits the genre exactly.
• Mechanic: "match 3", "tower defense". Players who type a mechanic know what they want, so a game that delivers it is a strong match.
• Theme and mood: "zombie survival", "cooking game", "relaxing games", "brain games". These describe the experience and often fit the keyword field.

The table below shows how hard each of these shapes was to rank for on the day we measured them, next to the long-tail phrases that combine them.

24 game keywords, measured in the US App Store

Measured by RespectASO on 6 October 2026. Popularity is RespectASO's estimate of how often a keyword is searched compared with others, from 1 to 100. Difficulty, from 1 to 100, says how hard the apps already on top are to pass. "In top 10 names" counts the top ten apps with the keyword in their name. How the numbers work.

Difficulty here runs from 39 for "halloween game" to 87 for "puzzle". 14 of the 24 keywords score 70 or more, and none score under 30. The long-tail phrases have a median difficulty of 58, against 76 for the head terms. The highest popularity among keywords under difficulty 50 belongs to "halloween game": 50, at difficulty 39.

To see what these keywords would bring your own app, and to measure them in any of the 175 storefronts, run them in RespectASO, free on your Mac.

Read the table by shape rather than keyword by keyword. If the genre, mechanic and long-tail rows sit well below the head terms, build your title and keyword field from them, and leave the generic words for when your game has the ratings to hold them.

Seasonal Keywords

Some game searches follow the calendar: "christmas game" around December, "halloween game" around October, "multiplayer party game" around the holidays. If your game fits a season, change your keyword field a few weeks ahead of it and change it back afterwards. The table shows where these terms stood on the day of the measurement, not at their peak.

Metadata Optimization for Games

Title Strategy

Game titles face a tension between brand and keywords. Your game's name is its brand, but the search algorithm weighs title words most. The usual answer is "Brand Name: Genre Description", for example "Wordsmith: Word Puzzle Game", which keeps the name and adds the genre words players type.

Subtitle and Keyword Field

Use the subtitle for your gameplay hook: what makes your game different. Use the keyword field for mechanics, theme variations and mood words ("relaxing", "offline") that players search for. Never repeat a word across title, subtitle and keyword field; Apple combines them for you.

Common ASO Mistakes in Games

• Targeting only generic keywords: "game" and "free game" are the first searches every game goes after. Check them in the table before you build on them, and lead with what makes your game specific: its genre, mechanic, theme and art style.
• Screenshots that show menus: Screenshots decide conversion in games more than in most categories. Show gameplay with a short caption on each frame, not settings screens.
• No localization: A puzzle game can work in any market, yet many indie games only optimize for English. The Country Opportunity Finder compares your genre keywords across storefronts so you can see where they are easiest to rank for.
• Metadata that never changes: Games change with new levels, modes and events. Let the subtitle and keyword field follow, highlighting new content and new themes.

Competitor Landscape

The category is led by studios with large user acquisition budgets, and their games sit on the broadest searches. Indie games break through in specific niches: a distinct art style, a new mechanic, a theme the big studios skip. Competitor analysis should look for the keywords and markets top games leave alone, rather than try to outrank them on their own names.

International Opportunity

Gameplay travels across languages, so games are well placed to grow abroad. Brazil, Indonesia and Turkey have large gaming audiences, and localizing only your keyword metadata for them is a small change. Measure your genre keywords in each storefront before you decide which to localize first.

How RespectASO Helps

Use Multi-Keyword Search to score genre and mechanic keywords in one go, and find the Sweet Spots: keywords searched often enough to matter where your game can still reach the top. Then use the Country Opportunity Finder to see which storefronts give your strongest keywords the best chance.
