ASO Rank Tracker — App Store Keyword Rankings & Change Alerts

Track where your app and your competitors rank for App Store keywords — and get alerted the moment those rankings move.

Most App Store keyword trackers hand you a flat CSV snapshot and leave you to diff it yourself. This actor does both: pull current rankings and — on a schedule — tell you exactly what changed since last time. Built for app publishers and ASO / mobile-growth agencies who need to watch keyword positions without paying enterprise-SaaS prices.

iOS (Apple App Store) is supported today via Apple's official iTunes Search API. Google Play tracking is a planned fast-follow.

What it does

1. Searches the App Store for each of your keywords in a given storefront (country).
2. Returns the top-ranked apps per keyword — name, developer, rating, review count, price, genre — with each app's rank.
3. If you provide your app's ID (and competitors'), it reports exactly where each ranks for every keyword.
4. In watchlist mode, it remembers the last run and emits only the changes.

Modes

Mode	What you get
snapshot (default)	Current top-N rankings for each keyword, every run
watchlist	Only what changed since the last run — for scheduled tracking

Watchlist change types

changeType	Meaning
rank_move	A tracked app moved up or down (delta is positive when it improved)
new_entrant	An app newly entered the top-N window for a keyword
dropped_out	An app fell out of the top-N window
baseline	First run for a keyword — current ranking saved as the baseline
no_change	Nothing changed for that keyword this run (free)

Set a Schedule in Apify (e.g. daily) and wire the dataset to a webhook/Slack for automatic rank-move alerts.

Input

Field	Required	Notes
keywords	✅	Search terms to track. Each keyword = one billable unit per run.
appId	optional	Your app's numeric iTunes ID (the number in apps.apple.com/app/id‹…›).
competitorAppIds	optional	Competitor iTunes IDs to track alongside yours.
country	optional	Storefront country code (default us). Rankings are storefront-specific.
topN	optional	Top apps per keyword + the window for entrant/drop detection (default 10).
resultsPerKeyword	optional	How deep to scan (1–200, default 50). Must be ≥ topN.
mode	optional	snapshot or watchlist (default snapshot).
watchlistName	optional	Namespaces the baseline in watchlist mode.
requestDelayMs	optional	Delay between keyword lookups (default 500ms) to respect Apple's rate limit.

Finding your app ID: open your app in the App Store; the URL ends in .../id1459969523 → 1459969523.

What you run	Cost
One-off snapshot, 20 keywords	$0.20
Daily watchlist, 20 keywords	~$6 / month
Weekly watchlist, 50 keywords	~$2 / month

Notes & limits

• Ranking = App Store search order. Position in Apple's search results for a term is the keyword ranking — the same signal ASO tools use.
• Top 200 only. Apple's Search API returns up to 200 results per query; an app below that is reported as not found for the keyword.
• Rate limits. Apple limits the Search API (~20 requests/min); requestDelayMs keeps runs polite. Rate-limited keywords retry with backoff, then emit a free error row if still failing.
• Data source: Apple's public iTunes Search API (itunes.apple.com/search). No API key required.
