Excel fix sheet:** 18 tabs (one per issue type), containing every URL and exact fix instructions — ready to hand off to a developer. Cloud Storage:** Both files are saved to your Google Drive /SEO Audits folder automatically. Slack Delivery:** Links to the generated files are posted directly back into your original Slack thread. ⚙️ How It Works A Slack message containing #Audit and a URL triggers the workflow. A POST request starts the crawl via your self-hosted Screaming Frog CLI API (built with Python + FastAPI, exposed publicly through a Cloudflare Tunnel — no static IP needed). The workflow polls the API every 2 minutes until the status is done, timeout, or failed. The crawl ZIP is downloaded and decompressed, triggering two simultaneous branches: Branch A (Executive Report): SEO Audit Parser → PageSpeed Insights → PSI Parser → Report Builder → HTML to PDF → Google Drive. Branch B (Developer Sheet): Full Data Parser → Tab Builder → Excel File Builder → Google Drive. Both Google Drive links are merged, logged to a Google Sheet, and posted back into the Slack thread. 🛠️ Key Technical Features Streaming CSV Parser:** Easily handles large crawl files up to 500MB without causing timeouts or memory crashes. Smart File Optimization:** Auto-skips massive all_inlinks.csv and all_anchor_text.csv files (reduces the unzipped payload from 450MB to 15MB). Advanced 403 Error Logic:** Splits 403 errors into three actionable categories: Your own site blocking the crawler (WAF/Cloudflare) Known bot-blocked platforms (Twitter, Wikipedia) Unknown external links requiring a manual check Archive Page Filtering:** Removes tags, pagination, feeds, and search pages from all issue counts so your data isn't skewed. Dynamic Health Score (0–100):** Algorithmically weighted by critical vs. warning issues. Universal CMS Support:** Works flawlessly with WordPress, Blogger, Shopify, and any other crawlable CMS. 📋 What You Need | Requirement | Notes | | :--- | :--- | | Screaming Frog SEO Spider | Licensed version (£199/year) required | | SF CLI API (Python/FastAPI) | Not included in this template — Contact creator below | | Cloudflare Tunnel | Free — exposes your local API publicly | | Google PageSpeed API Key | Free from Google Cloud Console | | PDF Conversion Service | Workflow is pre-configured for pdfendpoint.com | | Google Drive & Sheets | OAuth2 credentials for file storage and audit logging | | Slack | OAuth2 credentials for the trigger and delivery | | n8n (Self-Hosted) | Recommended for long execution times | ⚠️ Required n8n Environment Variables To ensure the workflow can process large sites without timing out, add these to your n8n .env file: N8N_DEFAULT_BINARY_DATA_MODE=filesystem EXECUTIONS_TIMEOUT=7200 N8N_RUNNERS_TASK_TIMEOUT=7200 NODE_OPTIONS=--max-old-space-size=8192 🚀 Quick Setup API Setup: Deploy the SF CLI API on your Windows machine/server and expose it via Cloudflare Tunnel.
