## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).

## 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`.

### Output

`recordType: "ranking"` (or `"baseline"`) — one row per top app per keyword:

```json
{
  "recordType": "ranking",
  "keyword": "meditation",
  "rank": 3,
  "appId": 571800810,
  "name": "Calm",
  "developer": "Calm.com",
  "rating": 4.77,
  "ratingCount": 1965687,
  "price": 0,
  "genre": "Health & Fitness",
  "isTracked": false,
  "store": "apple",
  "country": "us"
}
````

`recordType: "change"` — one row per detected change (watchlist mode). See the **Rankings** and **Changes** dataset views.

### Pricing

**$0.01 per keyword tracked.** You are charged once per **keyword scanned** per run (`keyword-tracked`), in both modes — no subscription, no per-run fee. Keywords that error (e.g. a transient rate limit) are **not** charged.

| 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.

# Actor input Schema

## `keywords` (type: `array`):

App Store search terms to track rankings for (e.g. "meditation", "budget planner", "photo editor"). Each keyword is one billable unit per run.

## `appId` (type: `string`):

Numeric iTunes track ID of the app you want to track (the number in an App Store URL: apps.apple.com/app/id‹THIS›). If set, each keyword reports where this app ranks. Leave empty to just see the top apps per keyword.

## `competitorAppIds` (type: `array`):

Numeric iTunes track IDs of competitor apps to track alongside yours. In watchlist mode you'll be alerted when any of them move.

## `country` (type: `string`):

Two-letter App Store country code (e.g. us, gb, de, jp). Rankings are storefront-specific.

## `topN` (type: `integer`):

How many top-ranked apps to return per keyword (also the window used to detect new entrants / drop-offs in watchlist mode).

## `resultsPerKeyword` (type: `integer`):

How deep to scan the App Store per keyword (1–200). Must be ≥ Top N. Scan deeper so a tracked app ranked below the top window is still found.

## `mode` (type: `string`):

snapshot (default) = return current rankings every run. watchlist = remember the last run and report only what CHANGED (rank moves, new top-N entrants, drop-offs). Watchlist is built for scheduled runs; the first run saves a baseline.

## `watchlistName` (type: `string`):

Names the baseline this run diffs against, so you can keep multiple independent watchlists. Ignored in snapshot mode.

## `minRankDelta` (type: `integer`):

Smallest rank change reported as a move. Small daily drift is noise, not signal — the default of 3 never reports a ±1 or ±2 wobble. Set to 1 to report every move (noisy). Ignored in snapshot mode.

## `rankDeltaFraction` (type: `number`):

Scales the reporting threshold with rank depth, so a move near the top matters more than the same move deep down. At 0.2, a move from rank 3 must cover 3 places to report, but a move from rank 43 must cover 9. Set to 0 to use the flat minimum at every depth. Ignored in snapshot mode.

## `requestDelayMs` (type: `integer`):

Milliseconds to wait between keyword lookups. Apple rate-limits the Search API (~20/min); the default keeps runs well-behaved. Raise it if you track many keywords and see rate-limit errors.

## Actor input object example

```json
{
  "keywords": [
    "meditation",
    "habit tracker"
  ],
  "appId": "389801252",
  "competitorAppIds": [],
  "country": "us",
  "topN": 10,
  "resultsPerKeyword": 50,
  "mode": "snapshot",
  "watchlistName": "default",
  "minRankDelta": 3,
  "rankDeltaFraction": 0.2,
  "requestDelayMs": 500
}
