## 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.md):

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

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

# README

## YouTube Similar Channels Finder

Find similar and competitor YouTube channels for any seed channel or topic — ranked by topic overlap and audience size, not just raw keyword match.

Give it a channel (handle, URL, or ID) or a topic keyword, and it returns a clean, ranked list of related channels with full subscriber, view, and video stats — ready for competitor analysis, niche research, or creator outreach.

### What you get

For every discovered channel:

- **channelTitle** and **channelUrl** — the channel name and a direct link
- **subscriberCount**, **totalViews**, **videoCount** — full public statistics
- **sizeTier** — `nano` (<10k), `micro` (10k–100k), `mid` (100k–1M), `macro` (1M–10M), or `mega` (>10M) so you can target channels in your own league
- **overlapScore** (0–100) — how similar the channel is to your seed, combining topic/keyword overlap with audience-size proximity
- **sharedKeywords** — the exact topic terms the channel has in common with your seed
- **country** and a trimmed channel **description**
- **seedChannelId / seedChannelTitle** — the seed (or topic) the result was matched against

Results are sorted by **overlapScore** descending, so the most relevant, best-fit channels are at the top. Impersonator, fan, and reupload clones are detected and pushed down automatically.

### Use cases

- **Competitor analysis** — map out the channels competing for your audience and benchmark their size
- **Find similar channels** — discover creators in the same niche as any channel you admire
- **Niche research** — explore a topic (e.g. "home espresso machine reviews") and surface the channels that own it
- **Creator outreach & partnerships** — find channels in your size tier for collabs, sponsorships, or cross-promotion
- **Influencer discovery** — build shortlists of vetted channels with real subscriber and view counts

### How to use

1. Enter a **Seed Channel** — a handle (`@mkbhd`), a channel URL, or a `UC...` channel ID. Or leave it blank and enter a **Topic Query** instead.
2. Optionally add a **Topic Query** to steer discovery toward a specific niche.
3. Set **Max Results** (default 25) — how many similar channels to return.
4. Set **Max Searches** (default 4) — how many discovery queries to run. Keep this low; more searches find more channels but take longer.
5. Run the actor — ranked results appear in the **Dataset** tab, ready to export to JSON, CSV, or Google Sheets.

You must provide at least one of **Seed Channel** or **Topic Query**.

### Output format

Each dataset record:

```json
{
  "seedChannelId": "UCBJycsmduvYEL83R_U4JriQ",
  "seedChannelTitle": "Marques Brownlee",
  "channelId": "UC...",
  "channelTitle": "UrAvgConsumer",
  "channelUrl": "https://www.youtube.com/channel/UC...",
  "subscriberCount": 3440000,
  "totalViews": 612000000,
  "videoCount": 540,
  "country": "US",
  "sizeTier": "macro",
  "overlapScore": 25,
  "sharedKeywords": ["tech"],
  "description": "Helping you make smarter buying decisions ...",
  "status": "success"
}
````

When the seed cannot be resolved and no topic query is given, the run fails with a clear message. When a topic genuinely returns no channels, the run finishes cleanly with no rows.

### How ranking works

- **Topic overlap** is the primary signal: the actor pulls keywords from the seed channel's title, description, and recent video titles (or from your topic query), then measures how many a candidate channel shares.
- **Size proximity** rewards channels in the same order of magnitude as your seed, so a 500k-subscriber channel surfaces peers of a similar scale rather than only the biggest names.
- **Clone suppression** detects impersonator, fan, and reupload channels (names that copy the seed) and ranks them far below genuine competitors.
- In **topic-only mode** (no seed channel), ranking blends topic overlap with channel popularity.

# Actor input Schema

## `seedChannel` (type: `string`):

A seed YouTube channel to find similar channels for. Accepts a handle (@mkbhd), a full channel URL, or a UC... channel ID. Leave blank to discover channels from a topic keyword instead.

## `topicQuery` (type: `string`):

Optional topic keyword (e.g. "tech reviews") used to discover channels around a niche, instead of or in addition to a seed channel. At least one of Seed Channel or Topic Query is required.

## `maxResults` (type: `integer`):

Maximum number of similar channels to return, ranked by overlap score (1–100).

## `maxSearches` (type: `integer`):

How many discovery search queries to run. Each search consumes more quota, so keep this low (1–8).

## Actor input object example

```json
{
  "seedChannel": "@mkbhd",
  "maxResults": 25,
  "maxSearches": 4
}
```

# Actor output Schema

## `results` (type: `string`):

One record per similar channel: seedChannelId, seedChannelTitle, channelId, channelTitle, channelUrl, subscriberCount, totalViews, videoCount, country, sizeTier (nano|micro|mid|macro|mega), overlapScore (0-100), sharedKeywords, description, status.
