Useful for:

• Content creators & marketers → quick inspiration for viral topics
• SEO/hashtag research → discover high-performing keywords
• Social media teams → automated trend reporting

⚙️ How It Works – Step by Step

1. Trigger

• Node: Manual Trigger
• Entry point of the workflow.
  → Can later be replaced with a Cron or Webhook trigger to run automatically.

---

2. API Call – YouTube

• Node: HTTP Request
• Calls the YouTube Data API v3 with:
  • chart=mostPopular
  • regionCode=DE
  • maxResults=50
• Returns a list of trending videos in Germany, including title, channel, views, likes, comments, and tags.

---

3. Split Items

• Node: Split Out
• Splits the API response (items[]) into individual items , so each video is processed separately.

---

4. Context & KPIs

• Node: Set
• Extracts key fields:
  • title, channel, publishedAt
  • views, likes, comments
• Calculates:
  • engagementRate = (likes + comments) / (views + 1)

Why?
Looking at views alone is misleading. Engagement rate reveals which videos truly resonate with the audience.

---

5. Ranking & Limit

• Node: Item Lists
• Sorts videos by highest engagement rate (descending).
• Limits results to the Top 20 videos.

Why?
This reduces noise and focuses only on the most relevant trends.

---

6. Collect Tags

• Node: Aggregate
• Collects all snippet.tags from the top videos.
• Merges them into a single keyword list.

---

7. Keyword Summary

• Node: Summarize
• Concatenates all collected tags into one string.

Result:
A compact hashtag/keyword list → ready to use for:

• Content ideas
• SEO/hashtag strategies
• Social media planning

---

📈 Why This Workflow Is Useful

• Automated trend analysis : no need to manually browse YouTube.
• Quality focus : uses engagement rate, not just views.
• Reusable : results can be:
  • stored in Google Sheets or Airtable,
  • sent to Slack/Telegram,
  • or used in a dashboard.

---

🚀 Possible Extensions

• Cron Trigger → run daily for automated reports.
• Notifier → send results directly to Slack, Discord, or Telegram.
• Storage → save trends in a database for historical analysis.
• AI Node → use GPT to summarize trends into “3 key insights of the day.”
