Run offline ASO audits on App Store metadata and surface keyword gaps using Astro MCP.
What is asc-aso-audit?
Audit App Store Connect metadata files locally for keyword waste, field utilization, formatting issues, and cross-locale consistency. Optionally integrate Astro MCP for competitor keyword gap analysis and Apple-generated tag alignment to optimize discoverability.
- Detect keyword waste: flags tokens appearing in both subtitle and keywords that waste indexing budget
- Check field utilization: warns when keywords (<90 chars) or subtitle (<20 chars) underuse available space
- Validate metadata formatting: catches bad keyword separators (spaces after commas, semicolons, pipes)
- Identify cross-locale gaps: flags keywords identical across locales, indicating missing localization
- Measure description keyword coverage: reports which keywords appear naturally in app description for conversion optimization
- Optional Astro MCP integration: extract competitor keywords and identify ranking gaps per store/locale

asc-aso-audit FAQ
No. Phase 1 (offline checks) runs without it. Phase 2 (competitor keyword gap analysis) requires Astro MCP to be configured and your app to be tracked.
Normalize it into the canonical `./metadata` layout (app-info and version subdirectories) before running the audit. The skill expects the standard ASC directory structure.
It tokenizes Arabic by whitespace and generates prefix-stripped variants (e.g., 'القرآن' → 'قرآن'). For CJK, it splits by punctuation or iterates characters. Keyword matching is case-insensitive and accounts for inflected forms.
No. Tags are Apple-generated and not editable. The skill uses them as context to check alignment with your positioning and recommends metadata/category changes that may improve future classification.
Yes. The skill audits all locales in your `./metadata` directory and compares keywords across them. Cross-locale gaps are flagged automatically.

description: Run an offline ASO audit on canonical App Store metadata under ./metadata and surface keyword gaps using Astro MCP. Use after pulling metadata with asc metadata pull.
asc ASO audit
Run a two-phase ASO audit: offline checks against local metadata files, then keyword gap analysis via Astro MCP. When available, include Apple-generated app tags as a discoverability signal.
Preconditions
- Metadata pulled locally into canonical files via
asc metadata pull --app "APP_ID" --version "1.2.3" --dir "./metadata". - If metadata came from
asc migrate exportorasc localizations download, normalize it into the canonical./metadatalayout before running this skill. - For Astro gap analysis: app tracked in Astro MCP (optional — offline checks run without it).
- For Apple-generated discoverability tags:
asc app-tags list --app "APP_ID" --output jsonworks when the API returns tags for the app.
Before You Start
- Read
references/aso_rules.mdto understand the rules each check enforces. - Identify the latest version directory under
metadata/version/(highest semantic version number). Use this for all version-level fields. - The primary locale is
en-USunless the user specifies otherwise.
Metadata File Paths
- App-info fields (
subtitle):metadata/app-info/{locale}.json - Version fields (
keywords,description,whatsNew):metadata/version/{latest-version}/{locale}.json - App name: May not be present in exported metadata. If
nameis missing from the app-info JSON, fetch it viaasc apps info listor ask the user. Do not flag it as a missing-field error.
Phase 1: Offline Checks
Run these 5 checks against the local metadata directory. No network calls required.
1. Keyword Waste
Tokenize the subtitle field (and name if available). Flag any token that also appears in the keywords field — it is already indexed and wastes keyword budget.
Severity: ⚠️ Warning
Example: "quran" appears in subtitle AND keywords — remove from keywords to free 6 characters
How to check:
- Read
metadata/app-info/{locale}.jsonforsubtitle(andnameif present) - Read
metadata/version/{latest-version}/{locale}.jsonforkeywords - Tokenize subtitle (+ name):
- Latin/Cyrillic scripts: split by whitespace, strip leading/trailing punctuation, lowercase
- Chinese/Japanese/Korean: split by
、,,or iterate characters — each character or character-group is a token. Whitespace tokenization does not work for CJK. - Arabic: split by whitespace, then also generate prefix-stripped variants (remove ال prefix) since Apple likely normalizes definite articles. For example, "القرآن" in subtitle should flag both "القرآن" and "قرآن" in keywords.
- Split keywords by comma, trim whitespace, lowercase
- Report intersection (including fuzzy matches from prefix stripping)
Optional: App Tag Alignment
App tags are Apple-generated labels that can appear in search results and product pages. They are not editable ASO metadata, but they are useful evidence for whether Apple's classification matches the intended positioning.
asc app-tags list --app "APP_ID" --output json
asc app-tags view --app "APP_ID" --id "TAG_ID" --output json
Use tags as context only:
- If visible tags reinforce the subtitle/keyword strategy, note the alignment.
- If tags point to an unintended category or use case, recommend metadata/category changes that may improve future classification.
- Do not promise that changing metadata will immediately change Apple-generated tags.
Optional: Official Apple Search Plan
When both App Store Connect and Apple Ads credentials are configured, use the experimental, read-only plan to join the selected metadata with official paid search evidence:
asc optimize search plan \
--app "APP_ID" \
--version "1.2.3" \
--ad-account "AD_ACCOUNT_ID" \
--country "US" \
--genre "PRODUCTIVITY_UTILITIES" \
--locale "en-US" \
--out-dir ".asc/optimization/1.2.3" \
--output markdown
- Authenticate App Store Connect with
asc authand Apple Ads separately withasc ads auth login; the two credential sets are independent. - Treat the generated CSV and JSON files as review artifacts. The command does not apply metadata, exact keywords, or negative keywords, and partial Apple Ads source failures stay visible in the report.
- Keep Apple's popularity, app-specific paid reach, paid search outcomes, and metadata coverage distinct. Do not infer organic rank or keyword difficulty from this plan.
2. Underutilized Fields
Flag fields using less than their recommended minimum:
| Field | Minimum | Limit | Rationale |
|---|---|---|---|
| Keywords | 90 chars | 100 | 90%+ usage maximizes indexing |
| Subtitle | 20 chars | 30 | 65%+ usage recommended |
Severity: ⚠️ Warning
Example: keywords is 62/100 characters (62%) — 38 characters of indexing opportunity unused
3. Missing Fields
Flag empty or missing required fields: subtitle, keywords, description, whatsNew.
Note: name may not be in the export — only flag it if the app-info JSON explicitly contains a name key with an empty value.
Severity: ❌ Error
Example: subtitle is empty for locale en-US
4. Bad Keyword Separators
Check the keywords field for formatting issues:
- Spaces after commas (
quran, recitation) - Semicolons instead of commas (
quran;recitation) - Pipes instead of commas (
quran|recitation)
Severity: ❌ Error
Example: keywords contain spaces after commas — wastes 3 characters
5. Cross-Locale Keyword Gaps
Compare keywords fields across all available locales. Flag locales where keywords are identical to the primary locale (en-US by default) — this usually means they were not localized.
Severity: ⚠️ Warning
Example: ar keywords identical to en-US — likely not localized for Arabic market
How to check:
- Load keywords for all locales
- Compare each non-primary locale against the primary
- Flag exact matches (case-insensitive)
6. Description Keyword Coverage
Check whether keywords appear naturally in the description field. While Apple does not index descriptions for search, users who see their search terms reflected in the description are more likely to download — this improves conversion rate, which indirectly boosts rankings.
Severity: 💡 Info
Example: 3 of 16 keywords not found in description: namaz, tarteel, adhan
How to check:
- Load
keywordsanddescriptionfor each locale - For each keyword, check if it appears as a substring in the description (case-insensitive)
- Account for inflected forms: Arabic root matches, verb conjugations (e.g., "memorizar" ≈ "memorices"), and case declensions (e.g., Russian "сура" ≈ "суры")
- Report missing keywords per locale — recommend weaving them naturally into existing sentences
- Do NOT flag: Latin-script keywords in non-Latin descriptions (e.g., "quran" in Cyrillic text) — these target separate search paths
Phase 2: Astro MCP Keyword Gap Analysis
If Astro MCP is available and the app is tracked, run keyword gap analysis. Run this per store/locale, not just for the US store — keyword popularity varies dramatically across markets.
Steps
-
Get current keywords: Call
get_app_keywordswith the app ID to retrieve tracked keywords and their current rankings. -
Check multi-store tracking: Query existing tracking for each locale's App Store territory. Report untracked stores as unavailable and continue the audit. Use
add_keywordsonly when the user separately authorizes tracking setup; empty rankings for an untracked store do not prove poor performance. -
Extract competitor keywords: Call
extract_competitors_keywordswith 3-5 top competitor app IDs to find keyword gaps. This is the highest-value Astro tool — it reveals keywords competitors rank for that you don't. Run this per store when possible. -
Get suggestions: Call
get_keyword_suggestionswith the app ID for additional recommendations based on category analysis. -
Check current rankings: Call
search_rankingsto see where the app currently ranks for tracked keywords in each store. -
Diff against metadata: Compare suggested and competitor keywords against the tokens present in
subtitle,name(if available), andkeywordsfields from the local metadata. -
Surface gaps: Report all gaps ranked by popularity score (highest first). Include the source (competitor analysis vs. suggestion).
Cross-Field Combo Strategy
When recommending keyword additions, consider how single words combine across indexed fields (title + subtitle + keywords). For example:
- Adding "namaz" to keywords when "vakti" is already present enables matching the search "namaz vakti" (66 popularity)
- Adding "holy" to keywords when "Quran" is in the subtitle enables matching "holy quran" (58 popularity)
Flag high-value combos in recommendations.
Skip Conditions
- Astro MCP not connected → skip with note: "Connect Astro MCP for keyword gap analysis"
- App not tracked in Astro → skip with note: "Add app to Astro with
mcp__astro__add_appfor gap analysis" - Store not tracked for a locale → report the gap and skip its rankings; tracking setup requires separate authorization
Output Format
Present results as a single audit report. The report covers only the latest version directory.

Notes
- Offline checks work without any network access — they read local files only.
- Astro gap analysis is additive — the audit is useful even without it.
- Run this skill after
asc metadata pullto ensure canonical metadata files are current. - For keyword-only follow-up after the audit, prefer the canonical keyword workflow:
asc metadata keywords diff --app "APP_ID" --version "1.2.3" --dir "./metadata"asc metadata keywords apply --app "APP_ID" --version "1.2.3" --dir "./metadata" --confirmasc metadata keywords sync --app "APP_ID" --version "1.2.3" --dir "./metadata" --input "./keywords.csv"when importing external keyword research
- After making changes, re-run the audit to verify fixes.
- The Field Utilization table includes promotional text for completeness, but no check validates its content (it is not indexed by Apple).
