An autonomous AI agent that visually audits eCommerce funnel pages for conversion friction using Claude 3.5 Sonnet.

![Agent Architecture]

Optimizing an eCommerce funnel usually requires expensive consultants or hours of manual review. This n8n workflow automates the "Heuristic Analysis" phase.

It iterates through a list of specific funnel URLs (Homepage, Collections, Product Page, Cart, Checkout), captures high-resolution screenshots, and uses Anthropic's Claude 3.5 Sonnet to perform a visual audit. It identifies specific friction points—like poor contrast, missing trust signals, or confusing layouts—and logs actionable fixes directly to Google Sheets.

• Multimodal AI Brain: Uses Claude 3.5 Sonnet (via Anthropic), which currently offers state-of-the-art performance for UI/UX visual reasoning.
• Full Funnel Coverage: Designed to audit every stage of the customer journey, from "Landing" to "Checkout."
• Context-Aware Analysis: The AI prompt is tuned to act as a "Senior UX Researcher," providing concise, 50-word critiques focused on conversion blockers.
• Automated Reporting: Syncs every finding back to your Google Sheet for immediate review.

• Orchestration: n8n
• Vision Model: Anthropic Claude 3.5 Sonnet
• Screenshots: ScreenshotAPI (or ScreenshotOne)
• Database: Google Sheets

1. Input: Reads a list of URLs from a Google Sheet (each row represents a specific step in the funnel).
2. Vision: Visits each URL and captures a full-page or viewport screenshot.
3. Reasoning: Sends the image to Claude 3.5 Sonnet with a prompt to identify "Conversion Friction."
4. Output: Writes the specific issue and recommendation back to the Google Sheet.

Create a Google Sheet with the following headers (case-sensitive if using the provided JSON):

• URL (The link to the page you want to audit)
• Analysis (Leave empty; the agent populates this)

You will need to configure the following in n8n:

• Anthropic API: Key for Claude 3.5 Sonnet.
• Screenshot Service: API Key for ScreenshotAPI (or similar).
• Google Sheets: OAuth2 connection.

• Download the funnel_audit.json file from this repository.
• In n8n, select "Import from File" and load the workflow.
• Update the specific API keys in the HTTP Request node and Analyze Image node.

• Empty States: If auditing a generic /cart URL without an active session, the agent will audit the "Empty Cart" state (which is still valuable for checking retention paths).
• Popups: Strong cookie banners or full-screen popups may obscure the audit if not blocked by the screenshot service.
