Finding YouTube Micro-Influencers

寻找YouTube微网红

Searches YouTube for channels in a specific niche, then filters by subscriber count to surface micro-influencers (typically under 100K subscribers) who have high engagement relative to their audience size. Ideal for affiliate programs and brand sponsorships where micro audiences convert better.
在YouTube上搜索特定细分领域的频道，然后通过订阅量筛选出相对于受众规模具有高互动率的微网红（通常订阅量低于10万）。非常适合联盟营销项目和品牌赞助，因为小众受众的转化率更高。

Workflow

工作流程

Progress:
- [ ] Step 1: Define niche and subscriber range
- [ ] Step 2: Build keyword and search term list
- [ ] Step 3: Run youtube-scraper
- [ ] Step 4: Filter and calculate view-to-sub ratio
- [ ] Step 5: Deliver ranked channel list
进度：
- [ ] 步骤1：定义细分领域和订阅量范围
- [ ] 步骤2：构建关键词和搜索词列表
- [ ] 步骤3：运行youtube-scraper
- [ ] 步骤4：筛选并计算播放量-订阅量比率
- [ ] 步骤5：交付排名后的频道列表

Step 1: Clarify Parameters

步骤1：明确参数

Ask the user for:
  • Niche/topic (e.g., "personal finance for millennials", "vegan cooking", "PC gaming")
  • Max subscribers (default: 100,000 — micro-influencer threshold)
  • Min subscribers (default: 5,000 — filters out very new channels)
  • Min videos (default: 20 — ensures established presence)
  • Number of channels to return (default: 30)
向用户询问以下信息：
  • 细分领域/主题（例如：“千禧一代个人理财”、“素食烹饪”、“PC游戏”）
  • 最大订阅量（默认值：100,000 — 微网红阈值）
  • 最小订阅量（默认值：5,000 — 过滤掉非常新的频道）
  • 最小视频数量（默认值：20 — 确保频道已建立一定影响力）
  • 返回的频道数量（默认值：30）

Step 2: Build Search Term List

步骤2：构建搜索词列表

Generate 3-5 YouTube search queries for the niche. Think like a viewer, not a marketer:
  • Personal finance → 
    "how to save money"
    , 
    "budget for beginners"
    , 
    "investing in your 20s"
  • Vegan cooking → 
    "easy vegan recipes"
    , 
    "vegan meal prep"
    , 
    "vegan on a budget"
  • PC gaming → 
    "budget PC build"
    , 
    "PC gaming tips"
    , 
    "indie game reviews"
为该细分领域生成3-5个YouTube搜索查询。要站在观众的角度思考，而非营销人员：
  • 个人理财 → 
    "how to save money"
    , 
    "budget for beginners"
    , 
    "investing in your 20s"
  • 素食烹饪 → 
    "easy vegan recipes"
    , 
    "vegan meal prep"
    , 
    "vegan on a budget"
  • PC游戏 → 
    "budget PC build"
    , 
    "PC gaming tips"
    , 
    "indie game reviews"

Step 3: Run the Actor

步骤3：运行Actor

Recommended — run_actor.js (handles waiting, output, and file saving automatically):
bash
undefined
推荐方式 — 使用run_actor.js（自动处理等待、输出和文件保存）：
bash
undefined

快速输出（在聊天中打印表格）

node scripts/run_actor.js

--input '{"param": "value"}'
node scripts/run_actor.js
--actor "apidojo~youtube-scraper"
--input '{"param": "value"}'

Save as CSV

保存为CSV文件

node scripts/run_actor.js
--actor "apidojo~youtube-scraper"
--input '{"param": "value"}'
--output YYYY-MM-DD_results.csv --format csv
node scripts/run_actor.js
--actor "apidojo~youtube-scraper"
--input '{"param": "value"}'
--output YYYY-MM-DD_results.csv --format csv

Save as JSON

保存为JSON文件

node scripts/run_actor.js
--actor "apidojo~youtube-scraper"
--input '{"param": "value"}'
--output YYYY-MM-DD_results.json --format json
> `APIFY_TOKEN` must be set in environment or `.env` file.

**If Apify MCP is available:**
Tool: apify:run-actor Actor: "apidojo~youtube-scraper" Input: { "searchQuery": "[SEARCH_TERM]", "maxResults": 50, "scrapeVideoDetails": false, "scrapeChannelDetails": true }

Run for each search query. Merge channel results, deduplicate by channel ID.

**REST API fallback:**
```bash
curl -X POST \
  "https://api.apify.com/v2/acts/apidojo~youtube-scraper/runs?token=$APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "searchQuery": "[SEARCH_TERM]",
    "maxResults": 50,
    "scrapeChannelDetails": true
  }'
Wait for 
SUCCEEDED
. Fetch dataset.
node scripts/run_actor.js
--actor "apidojo~youtube-scraper"
--input '{"param": "value"}'
--output YYYY-MM-DD_results.json --format json
> 必须在环境变量或`.env`文件中设置`APIFY_TOKEN`。

**如果Apify MCP可用：**
工具: apify:run-actor Actor: "apidojo~youtube-scraper" 输入: { "searchQuery": "[SEARCH_TERM]", "maxResults": 50, "scrapeVideoDetails": false, "scrapeChannelDetails": true }

为每个搜索词运行一次。合并频道结果，按频道ID去重。

**REST API备选方案：**
```bash
curl -X POST \
  "https://api.apify.com/v2/acts/apidojo~youtube-scraper/runs?token=$APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "searchQuery": "[SEARCH_TERM]",
    "maxResults": 50,
    "scrapeChannelDetails": true
  }'
等待状态变为
SUCCEEDED
，然后获取数据集。

Step 4: Filter and Score

步骤4：筛选与评分

Apply subscriber range filter. Then calculate view-to-subscriber ratio as the micro-influencer quality signal:
view_ratio = (total_views / subscriber_count)
recent_momentum = avg_views_last_10_videos / subscriber_count
High 
recent_momentum
(>0.5) = channel punching above its weight — ideal micro-influencer.
应用订阅量范围筛选。然后计算播放量-订阅量比率，作为衡量微网红质量的指标：
view_ratio = (total_views / subscriber_count)
recent_momentum = avg_views_last_10_videos / subscriber_count
较高的
recent_momentum
（>0.5）意味着频道表现超出预期 — 是理想的微网红人选。

Step 5: Format Output

步骤5：格式化输出

Troubleshooting

故障排除

Only large channels in results: YouTube search ranks by relevance + views, surfacing big channels first. Try more niche-specific search terms or filter more aggressively on subscriber count. No contact info: Most YouTubers list business email in the About tab. If missing from scraper output, check the channel URL manually. Stale subscriber counts: YouTube data on Apify can be 24-72h old. For final outreach list, verify top picks manually.
结果中只有大型频道： YouTube搜索按相关性+播放量排序，大型频道会优先显示。尝试使用更细分的搜索词，或更严格地筛选订阅量。 无联系方式： 大多数YouTuber会在“关于”标签页列出商务邮箱。如果爬虫输出中没有，手动查看频道链接。 订阅量数据过时： Apify上的YouTube数据可能滞后24-72小时。对于最终的拓展名单，手动核实首选频道的信息。
