Generate AEO snippets from Google PAA with SerpApi and Gemini

This n8n template automates the identification & optimisation of Answer Engine Optimisation (AEO) opportunities by extracting Google "People Also Ask" (PAA) data to generate high-authority response snippets.

As search engines shift toward AI-generated overviews and answer engines like Perplexity, appearing in the "Citation" or "Snippet" layer is critical for maintaining organic visibility. This workflow identifies the exact questions users are asking and drafts structured answers designed to win featured snippets.

How it works

• The workflow initiates via a Form Submission with a target keyword.
• It uses the SerpApi node to scrape real-time Google Search results, specifically targeting the related_questions (PAA) array.
• An Item Lists node cleans the data to ensure only high-relevance questions are processed.
• The questions are sent to a Gemini node with a specialized prompt to draft a 40-50 word answer optimized for "Speakable" Schema and featured snippet logic.
• The finalised Q&A pairs are then appended to a Google Sheet, creating a ready-to-publish content gap report for the agency's editorial team.

How to use

• Replace the keyword placeholder in the HTTP/SerpApi node with your client’s target search term.
• Connect your Notion or Google Sheets account to the final destination node to house the results.
• Adjust the Schedule Trigger frequency based on how often you perform keyword research for your clients.

Requirements

• SerpApi Account: To programmatically access Google’s "People Also Ask" data.
• AI Credentials: An API key for Gemini or OpenAI to generate the response text.
• Destination App: A Notion workspace, Google Sheet, or Airtable base to store the output.

Customising this workflow

• Competitor Tracking: Modify the SerpApi parameters to include a specific domain to see what questions your competitors are currently ranking for.
• Schema Generation: Add a second AI node to automatically wrap the answers in JSON-LD Question and AcceptedAnswer schema code for immediate dev-handoff.
• Multi-lingual AEO: Add a translation node before the final output to localise answer snippets for international SEO campaigns.
• Slack Notification: Add a Slack node at the end to notify the account manager to review the new optimisation opportunities.
• AEO Master Log: Maintain a database to store all Q&A pairs for each client.
