n8n CRO Audit Workflow: DeepSeek + Sheets + Gmail + Telegram

Instant CRO Roasts + Actionable Fixes for Your Landing Pages (Auto-Logged, Emailed, and Alerted)

Turn landing page URLs into a complete CRO audit: this n8n workflow collects a URL via Form submission, extracts page text, uses the DeepSeek deepseek-v4-flash model to generate a JSON score + roast + 10 prioritized recommendations, logs everything to Google Sheets, emails the report with Gmail, and sends low-score Telegram alerts—plus an automatic weekly digest every Monday.

What this workflow does

• Captures inputs: Receives a landing page URL and recipient email through an n8n Form.
• Validates submissions: Normalizes and checks URL/email; if invalid, sends a Gmail rejection email.
• Scrapes and prepares content: Fetches the landing page HTML via HTTP, strips it to clean text, and limits extracted content size for analysis.
• Generates a CRO audit with DeepSeek: Sends the cleaned text to an OpenAI-compatible chat model using deepseek-v4-flash, returning JSON with an overall score, sub-scores, roast summary, and 10 prioritized recommendations.
• Formats and logs results: Parses the JSON, derives a letter grade, prepares a plain-text report, and appends an audit record to Google Sheets under the “Audits” tab.
• E-mails the report: Sends the full audit report to the submitter via Gmail.
• Telegram alerts: Posts a Telegram alert when the score is below 75, then shows a completion message.
• Weekly digest: Every Monday at 9:00, reads the audit log from Google Sheets, computes last-7-days stats, generates a short digest with the same AI model, and emails it via Gmail.

Use cases

• SaaS teams running repeatable CRO audits for new landing pages
• Automation engineers needing an end-to-end n8n “audit-to-report” pipeline
• Growth operators who want score tracking in Google Sheets and instant Telegram escalations
