App Store keyword research in 2026 is not “collect 500 keywords in a spreadsheet.” A working semantic map clusters intent and prioritizes what belongs in title (30 chars), subtitle (30), keyword field (100)—and what you deliberately do not index because ASA or CPP handles it better. Below is a step-by-step process without stuffing that kills organic growth—see 9 ASO mistakes.
Data sources: free and paid
- Apple Search Ads Keyword Planner — Search Popularity by country; baseline for head terms.
- App Store Connect — acquisition search terms (limited but free).
- ASA search match / discovery — real queries that convert to installs.
- Competitors — top-5 category title/subtitle + manual long-tail from App Store search suggest.
- ASO tools — position tracking and gap analysis; not the only source of truth.
Intent clusters: how to group keywords
Split semantics into four buckets:
Brand. App name and typos—defend with ASA brand; do not waste subtitle space.
Category head. “fitness tracker”, “pdf scanner”—high volume, fierce competition; partly cover with paid.
Feature / use case. “workout planner women”, “scan document iphone”—core organic ASO in subtitle and keyword field.
Competitor / comparison. Trademark risk; sometimes works in keyword field with moderation risk.
Keyword map: priority table
| Cluster | Placement | Success metric |
|---|---|---|
| Brand | Title (if short) + ASA brand | Brand SOV, CVR > 60% |
| Head category | Title + ASA discovery | Top 10 rank, impressions trend |
| Long-tail feature | Subtitle, keyword field | Top 5 on 10–20 terms |
| Seasonal | Promo text, CPP, In-App Events | PPV lift in event window |
Title and subtitle: rules without stuffing
Title is the strongest signal. Formula: Brand + primary category term or Brand + core benefit within 30 characters including spaces. Subtitle—second layer: 2–3 long-tail terms as a natural phrase, without repeating every title word.
Keyword field—synonyms and typos; do not duplicate title/subtitle words (Apple ignores repeats). After metadata changes wait 48–72h for indexing before conclusions; sharp impression drops—impression diagnostics.
Long-tail vs head: where to invest
New apps without 4.5+ ratings and thousands of installs: realistic path is long-tail top 3–5, not head #1. Run head terms in ASA for CVR and SOV data, then move winning phrasing into subtitle. Compare paid vs organic—ASO vs Apple Search Ads.
Localizing the keyword map
Do not translate EN core literally. DE users use different collocations; JP mixes katakana and kanji. Separate keyword map per locale plus localized screenshots—screenshot optimization.
FAQ
How often to update the keyword field?
Every 4–8 weeks when you have new feature terms or ASA data. More often risks losing stable ranks without reason.
Search Popularity 5—is the keyword worth it?
Depends on difficulty and CVR. Low SP + high intent often beats high SP at position 50.
Separate Google Play keyword map?
Yes. Play uses short + full description; different logic—see Google Play ASO 2026.
