Get a free PageSpeed Insights API key from Google Cloud Console\n2. Create Google Sheet with columns: URL, Site Name, Category, Alert Threshold, Last_Processed_Date and Device.\n3. Set up Google Sheets API credentials\n4. Configure notification preferences (Slack, email, etc.)\n5. Set audit schedule (daily, weekly, or custom)\n6. Define performance thresholds for alerts\n\n## Requirements\n- Google PageSpeed Insights API key (free)\n- Google Sheets API access\n- n8n instance (cloud or self-hosted)\n- Optional: Slack/email for notifications\n\n## Google Sheet Structure\n**Input Sheet (\"sites\"):**\n- URL, Site_Name, Category, Alert_Threshold, Last_Processed_Date and Device.\n\n**Results Sheet (\"audit_results\"):**\n- Date, URL, Site_Name, Device, Performance_Score, LCP, FID, CLS, Recommendations, Full_Report_URL\n\n## API Usage (On-Demand)\nPOST to webhook:\n```json\n{\n  \"url\": \"https://example.com\",\n  \"site_name\": \"Example Site\",\n  \"alert_threshold\": 75\n}\n```\n\n## How to customize\n- Add custom performance thresholds per site\n- Include additional metrics (accessibility, SEO, best practices)\n- Connect to other dashboards (Data Studio, Grafana)\n- Add competitor benchmarking\n- Integrate with project management tools for issue tracking\n- Set up different notification channels based on severity"
