Games are the largest, most competitive, and most creatively-optimized category on mobile. They also have ASO mechanics that differ substantially from non-game apps. This guide walks through what's unique about ASO for games, and how the publishers who consistently rank handle it.
Why games are different
A few structural differences shape the entire ASO playbook:
- Sub-category structure. The iOS Games category has 19 sub-categories (Action, Adventure, Puzzle, Racing, RPG, Strategy, Casino, and so on). Rankings are primarily per-sub-category. This means the competitive set is narrower than "all games" but deeper than most non-game categories.
- Pure discovery-first. Users browse game charts far more than they browse non-game category charts. Chart placement drives a larger share of organic installs for games than for utilities or productivity apps.
- Visual-first evaluation. A 10-second first impression, overwhelmingly visual. Icon, screenshots, and preview video carry a disproportionate share of conversion weight.
- Keyword mechanics shift. Brand-name keywords matter less than genre + mechanic keywords (e.g., "match-3 puzzle", "open-world RPG", "idle tycoon").
- Live-ops as an ASO lever. Games that run regular events, seasonal content, and limited-time modes feed In-App Events, which feed search visibility and chart retention.
Keyword strategy for games
For most games, the target keyword basket is a three-layer structure:
Layer 1: Brand terms. If your game has recognizable brand or IP, capture the brand plus any short-form variants. "Candy Crush", "Clash", "FIFA" — these convert at very high rates when users search for them directly.
Layer 2: Genre + mechanic. The largest organic install driver for mid-ranked games. Examples:
- "match 3 puzzle"
- "idle tycoon"
- "open-world RPG"
- "roguelike card"
- "racing simulator"
These keywords have meaningful volume and users searching them have high install intent.
Layer 3: Descriptor and mood. Lower volume but often less competitive.
- "cozy puzzle games"
- "hyper casual arcade"
- "offline strategy"
- "no-wifi games"
Layer 3 terms are where mid-sized games consistently win against bigger competitors — the incumbents don't bother to optimize for them, and intent is strong.
Screenshot strategy
Games break the default "caption everything" screenshot convention because the visuals themselves are the value proposition. The frameworks that consistently win:
For RPGs, adventure, narrative games:
- Screenshot 1: Hero character art or in-game cinematic moment with a subtitle like "Your quest begins"
- Screenshot 2: Key combat or exploration moment
- Screenshots 3-5: Feature callouts (classes, world map, crafting system)
- Screenshot 6+: Supporting polish — reviews, awards, social mechanics
For puzzle, casual, hyper-casual:
- Screenshot 1: A single compelling in-play screenshot with overlaid text explaining the hook ("Match 3 to clear the board")
- Screenshot 2: A "satisfying moment" — a big combo, a level complete animation, a reward screen
- Screenshots 3-5: Progression mechanics, variety of levels or modes
- Screenshot 6+: Social proof and awards
For strategy, simulation, management:
- Screenshot 1: A sprawling screenshot of your world or empire at depth — show scale
- Screenshot 2: A pivotal decision moment (e.g., a battle, an economy panel)
- Screenshots 3-5: Core systems (units, tech tree, base building)
- Screenshot 6+: Multiplayer, PVP, or endgame depth
The constant across genres: the first screenshot must communicate what the player does, not just what the game looks like. "Looks beautiful" doesn't convert; "I can see myself playing this" does.
The preview video
For games, preview video is the single highest-leverage non-core creative asset. A well-made 15-30 second iOS preview video can lift store-page conversion by 20-40% on top of static screenshots.
What wins:
- Show gameplay within the first 2 seconds. Cinematic intros bleed user attention. Auto-play starts muted, so the opening must be visually compelling without audio.
- Build in captions / overlaid text. Users who watch without sound (majority) need textual reinforcement of what's happening.
- End on a win moment. The last frame sticks in memory. Finish on a combo, a level complete, a boss defeat — not a fade-out.
- Keep it under 30 seconds. Apple caps at 30s; shorter often performs better.
Don't recycle your TikTok or YouTube trailers. Those are optimized for different contexts. A store-page preview video is a dedicated creative asset.
In-App Events — the most under-used games ASO lever
Apple's In-App Events allow up to 5 concurrent or upcoming events, each running up to 31 days, surfaced both on your product page and in search results. For games, this is essentially a free promotional slot for every seasonal push, tournament, or content drop you ship.
Common event types for games:
- Tournament / competition — weekly or bi-weekly ranked events
- Limited-time mode — variant gameplay (e.g., "Halloween mode", "Darkness Ascending event")
- New character / content drop — a new playable character or storyline
- Seasonal theme — reskin or special rules for a holiday window
- Live stream or community event — tied to a Twitch stream, community milestone, or developer Q&A
Games that rotate events weekly consistently out-rank games that never use the feature, holding other signals equal. The events drive both chart velocity (new installs from event hype) and product-page conversion (users see "event active now" and convert higher).
In our data, games that ran at least one active In-App Event continuously for 6+ months held category rank 2-3x longer than games that didn't use the feature at all.
Rating and review velocity for games
Games have the widest rating distribution of any category — both some of the highest-rated apps (curated indie hits) and some of the lowest (pay-to-win free-to-play games that monetize aggressively).
Keys to maintaining healthy ratings for games specifically:
- Prompt after positive moments only. After a level complete, a boss defeat, a milestone achievement — never after a defeat, an IAP failure, or an ad interaction.
- Gate on active-day threshold. Don't prompt until the player has returned at least 3 times. Early-dropped players skew negative.
- Never prompt inside a paywall or monetization flow. Apple flags this and it generates backlash.
- Respond to negative reviews publicly. Google Play shows your response. Thoughtful responses improve your overall rating perception even if the individual review stays.
Sub-categories and positioning
Picking the right sub-category at submission is irreversibly consequential. You'll rank primarily within that sub-category chart, and users browsing that chart set their expectations accordingly.
Two practical rules:
- Pick accuracy over opportunity. Don't game the taxonomy by picking Puzzle when your game is actually Strategy. Mismatch produces low-intent installs that rate poorly.
- Use the secondary sub-category for breadth. If your game has two clear genres, use primary for the dominant one and secondary for the other. You'll appear on both charts (weighted toward primary).
The live-ops multiplier
The biggest difference between top-decile and median games isn't their launch; it's their post-launch operation. Games that ship regular content drops, run rotating events, and respond to community signals maintain chart rank 3-6x longer than games that launch and then go dormant. Everything above — keyword work, creative refreshes, rating management, In-App Events — compounds only if you're shipping.
Plan ASO as an ongoing component of live-ops, not a one-time launch task.
