App Store Optimization (ASO) Checklist for 2026

If you shipped an app and organic downloads are flat, the problem is almost never the product — it is visibility. The aso checklist 2026 below distills everything we apply when we launch and grow apps on behalf of clients: from keyword research through AI-generated search rows to post-launch conversion tuning. Work through each section once at launch, then revisit quarterly.

1. Keyword Research and Title Strategy

The title field carries the highest algorithmic weight on both the App Store and Google Play. Spend the most time here.

• Lead with your primary keyword. Place your single strongest term in the first 30 characters of the title — that portion is indexed most heavily and rarely truncated in search results.
• Use the subtitle (iOS) / short description (Android) as a second keyword slot. These fields are indexed and displayed in search, so treat them like metadata, not marketing copy.
• Build a keyword bank before you write anything. Pull from App Store search suggestions, competitor keyword analyses (tools like AppFollow, Sensor Tower, or AppTweak all work), and your own user interviews. Sort by volume × relevance.
• Localize aggressively. A separate keyword list for each major market — English, Russian, Uzbek for CIS-targeting apps — can double organic installs without any additional spend.

Tip: Avoid keyword stuffing. Apple’s review team penalizes titles that read like a list of terms. Write for humans first, then optimize the keyword slot field (100 characters on iOS) with the residual terms you couldn’t fit in the title.

2. Metadata: Description, Keywords Field, and What-s New

Field	iOS	Android
Title	30 chars, indexed	50 chars, indexed
Subtitle / Short description	30 chars, indexed	80 chars, indexed
Keyword field	100 chars, indexed	N/A
Long description	Not indexed	Indexed (first 167 chars weighted heavily)
What’s New	Not indexed	Not indexed

On iOS, the keyword field is your leverage point — comma-separate terms, no spaces after commas, no repetition of words already in the title or subtitle. On Android, front-load the long description with your core use-case sentence because the first ~167 characters render above the fold.

The “What’s New” section is not indexed for search, but it is read by users before updating and by App Store editors before featuring. Keep it human and benefit-led, not a git commit log.

3. Visual Assets: Screenshots, App Preview Video, and Icon

Conversion rate within the product page (store listing CVR) is the multiplier on your keyword rankings. A listing that ranks #3 but converts at 4% beats a #1 ranking that converts at 2%.

Icon

• High contrast, single focal element, no text.
• Test two or three variants using Apple’s Product Page Optimization (PPO) tool before locking.
• Avoid overly literal depictions — abstract and branded icons outperform literal ones on long-tail search.

Screenshots

• The first two screenshots carry disproportionate weight because they appear inline in search results before a user taps through.
• Use caption overlays (large, benefit-focused, 5–7 words max) rather than relying on the UI to explain itself.
• Maintain visual consistency: same font system, same color palette across all frames.

App Preview Video

• Autoplay with no sound — design for muted viewing. Add captions.
• Keep it under 30 seconds. The first 6–8 seconds must convey the core value proposition.
• Video lifts CVR by 20–35% in most A/B tests we have run, but a badly produced video can lower it. If you are not confident in production quality, launch without one and add it later.

4. Ratings, Reviews, and the Feedback Loop

The App Store algorithm treats average rating, rating velocity (new ratings per week), and developer response rate as ranking signals.

• Prompt at the right moment. The SKStoreReviewRequest API should fire after a user completes a positive action (task saved, workout finished, recipe cooked) — not on launch or after an error. Apple allows three prompts per year per user.
• Respond to every negative review within 48 hours. A thoughtful response does not just appease the reviewer — it is read by thousands of prospects evaluating your app.
• Track rating velocity. A sudden drop in ratings is the earliest warning sign of a UX regression, often surfacing before your analytics do.

5. AI-Powered Search Rows and Discovery (2026-Specific)

Apple’s “Games We Love,” “Apps We Love,” and, increasingly, AI-curated discovery rows surface apps based on signals beyond keyword match: engagement depth, session length, retention D1/D7/D30, and in-app events.

• Publish In-App Events regularly. Challenges, content drops, and seasonal events feed the discovery algorithm and appear as event cards in search results. Aim for at least one event per month post-launch.
• Optimize for AI search surfaces. Apple Intelligence and Google’s Gemini-integrated Play search now answer natural language queries (“best app for tracking space launches”). Your long description and in-app event copy should use natural, conversational language alongside traditional keywords.
• Custom Product Pages (iOS 15+). Create 35 variant pages targeting different audience intents (gift-givers vs. power users vs. first-timers). Run paid or owned traffic to the relevant variant, then let organic data inform which angle converts best.

6. Localization and Market-Specific Tuning

Localization is the highest-ROI growth lever that most studios skip. Translating your metadata into the language of a target market — Russian for CIS, Uzbek for the domestic market, Arabic for MENA — typically costs less than a week of development time but can unlock entirely new ranking clusters.

A few rules we follow across our published apps:

• Translate by a native speaker with product context, not a generic translation service.
• Localize screenshots — replace English captions with the target language. A Russian user scanning search results skips English-captioned screenshots.
• Check local competitor keywords separately; search behavior differs meaningfully between markets.

7. Post-Launch Monitoring Cadence

ASO is not a one-time task. Set a calendar reminder for these checks:

• Weekly: Keyword rank movements, rating velocity, crash rate (crashes suppress ranking).
• Monthly: CVR by traffic source in App Analytics, review sentiment themes, competitor moves.
• Quarterly: Full keyword refresh, screenshot A/B test cycle via PPO, update metadata for new features.

A well-maintained listing compounds over time. The apps in our portfolio that drive the most organic volume are not necessarily the ones with the largest launch budgets — they are the ones with the most consistently maintained store listings.

Summary: Your 2026 ASO Priority Stack

Priority	Action	Impact
1	Keyword-first title + subtitle	Ranking
2	First two screenshots optimized	CVR
3	SKStoreReview at right moment	Ratings
4	Monthly In-App Events	Discovery
5	Localized metadata per market	New audience reach
6	Quarterly keyword refresh	Sustained ranking

Building an app that deserves great ASO — tight onboarding, strong retention loops, a reason for users to leave 5 stars — is the upstream work that makes everything above compoundable.
