Step-by-Step Workflow Explanation

🗓 1. Scheduled Trigger (Support Workflow)
Marks all rows in the sheet as "notchecked" in the checkstatus column.
This is the user-defined frequency trigger (e.g. weekly, daily).
Triggers the main workflow.

🚀 2. Main Workflow Trigger
Starts when a row with checkstatus = notchecked is found.

🔍 3. HTTP Node (SerpAPI Call)
Sends a request to SerpAPI for each keyword.
Fetches the current Google SERP for that keyword.

🧠 4. JavaScript Node (Parse Position)
Loops through the SERP results and finds the position of the target URL.
Extracts and returns the current rank.

✍️ 5. Google Sheets Node (Update Data)
Writes the new ranking into the spreadsheet.
Updates the currentposition and sets checkstatus to "checked".

🔀 6. Switch Node (Compare Rankings)
Compares previousposition with currentposition:
If rank has improved → send positive alert.
If rank has dropped → send negative alert.
If unchanged → no alert.

📩 7. Notification Nodes (WhatsApp / Email)
Sends a message to chosen channels when a change is detected.

How to Set Up This Workflow

✅ Step 1: Use This Google Sheets Template
To get started quickly, make a copy of the template below:

👉 Google Sheets Template

This template includes the required structure:
keyword
Website_url
position
timestamp
checkstatus

> ⚠️ Be sure to make your own copy to edit and connect via the Google Sheets node.

🔐 Step 2: Configure Your APIs
SerpAPI:** Get API key from serpapi.com/manage-api-key
Set credential type to Generic in n8n for compatibility.
Google Sheets, Email & WhatsApp:* Use the instructions found in each node’s *Docs tab** to connect your accounts.

📦 Step 3: Import the Workflow
Both the main keyword tracking workflow and the supporting scheduler workflow are in one file

▶️ Step 4: The workflow will start
Since the check status columns will be 'notChecked' schedule workflow.
The update sheets node will update each processed row's checkstatus to 'checked' and the workflow will process the next row
the schedule trigger workflow will update checkstatus = notchecked and triggers the keyword tracking automatically.

🎉 Done!
From now on, your keyword positions will be monitored at the frequency you set. You’ll receive WhatsApp and/or email updates only when rankings change. in case you need customized workflows or wanna reach out here is my twitter and email.
