Perform SEO Keyword Research & Insights with Ahrefs API and Gemini 1.5 Flash

This n8n workflow automates SEO keyword research by querying the Ahrefs API for keyword data and related keyword insights. The enriched data is then processed by an AI agent to format a response and provide valuable SEO recommendations.

Perfect for SEO specialists, content marketers, digital agencies, and anyone looking to gain valuable insights into keyword opportunities to boost their rankings.

⚙️ How This Workflow Works

This workflow guides you through the entire SEO keyword research process, from entering the initial keyword to receiving detailed insights and related keyword suggestions.

1. 🗣️ User Input (Keyword Query)

• The user enters a keyword they want to research.
• This input is captured by the Chat Input Node, ready for analysis.

2. 🤖 AI Agent (Input Verification)

• The AI Agent reviews the keyword input for any grammatical errors or extra commentary.
• If necessary, it cleans the input to ensure a seamless query to the API.

3. 🔑 Ahrefs API (Keyword Data Retrieval)

• The cleaned keyword is sent to the Ahrefs Keyword Tool API.
• This retrieves a detailed report including metrics like search volume, keyword difficulty, and CPC.

4. 💡 Related Keywords Extraction (Using JavaScript Function)

• The workflow uses a JavaScript function to extract main keyword data and 10 related keywords data from the Ahrefs response.
• You can tweak the script to adjust the number of related keywords or the level of detail you want.

5. 🧠 AI Agent (Text Formatting)

• The aggregated data, including both the main keyword and related keywords, is sent to an AI agent.
• The AI agent formats the data into a concise, readable format that can be shared with the user.

6. 📨 Final Response

• The formatted text is delivered to the user with keyword insights, recommendations, and related keyword suggestions.

✅ Smart Retry & Error Handling

Each subworkflow includes a fail-safe mechanism to ensure:

• ✅ Proper error handling for any issues with the API request.
• 🕒 Failed API requests are retried after a customizable period (e.g., 2 hours or 1 day).
• 💬 User input validation prevents any incorrect or malformed queries from being processed.
