Automated Landing Page Conversion Rate Optimization (CRO) Analysis with Multi-AI Agents - n8n Workflow

Conversion Rate Optimization (CRO) specialists looking to scale their analysis process.
CMOs and business founders needing fast, expert feedback on their landing page performance.
Developers seeking advanced examples of an n8n workflow leveraging multiple LLMs simultaneously.
Users looking for high-impact n8n templates for marketing automation.

This sophisticated n8n workflow solves the problem of slow and manual landing page auditing. By integrating a dynamic AI agent with powerful language models like OpenAI GPT, Google Gemini, and Mistral AI, it delivers immediate, high-quality, and unconventional Conversion Rate Optimization (CRO) insights. The core of this n8n workflow is the intelligent AI Agent n8n node, which performs a deep, personalized "roast" of the submitted landing page content, generating 10 specific, actionable, and 2024-relevant recommendations. This n8n template streamlines the process from submitting a URL to receiving analysis across multiple communication channels (Gmail, Telegram, WhatsApp), making advanced CRO analysis instantly scalable using n8n.

This n8n workflow begins with the Landing Page Url form trigger, which captures the target URL. Next, the Scrape Website n8n node executes an HTTP request to retrieve the page content. This content is then fed into the highly customized AI Agent n8n node. This agent operates under strict instructions to act as a top 0.1% CRO expert. To achieve high reasoning capabilities, the agent dynamically utilizes several integrated tools, including the OpenAI Chat Model (the primary language model), the Message a model in Google Gemini tool, and the Extract text in Mistral AI tool, alongside search tools like SearXNG and SerpAPI for real-time context. Once the AI Agent completes its comprehensive analysis and structured output (the Roast and 10 Recommendations), the final results are simultaneously routed to three separate n8n nodes: Send a message (Gmail), Send a text message (Telegram), and the Rapiwa n8n node for WhatsApp delivery. This ensures the valuable CRO insights generated by the n8n workflow reach the user instantly through their preferred communication channel.

To utilize this advanced n8n workflow, follow these setup steps:

1. Import the n8n workflow: Copy the provided JSON code and import it directly into your n8n instance using the 'New' button and selecting 'Import from JSON'.


2. Set up Credentials: You must configure credentials for the various services used in this n8n template:

1. Activate the n8n trigger: Once credentials are set, activate the Landing Page Url form trigger n8n node. You can then access the public form URL to begin submitting landing pages for analysis.

Landing Page Url (Form Trigger n8n node): The initial n8n trigger that starts the automation. It provides a simple public form interface to collect the URL of the landing page to be analyzed.
Scrape Website (HTTP Request n8n node): Function: Fetches the raw HTML content of the submitted URL. Key Configuration: Uses an expression ={{ $json['Landing Page Url'] }} to dynamically input the target link.
AI Agent (LangChain Agent n8n node): Function: The central intelligence hub. It orchestrates the analysis using a highly detailed prompt instructing it to perform a conversion-focused "roast" and generate 10 non-trivial CRO ideas. Key Configuration: Connected to six different LLMs/Tools for enhanced reasoning and creativity, ensuring the output is personalized and high-quality.
OpenAI Chat Model (LLM n8n node): Function: Provides the core large language model capabilities to the AI Agent. Key Configuration: Uses a high reasoning effort setting (reasoningEffort: "high").
Message a model in Google Gemini (Tool n8n node): Function: Integrated as a tool to leverage Google's Gemini 2.5 Flash model for diversified AI output and perspective.
Send a message (Gmail n8n node): Function: Delivers the final CRO report (the output of the AI Agent) via email. Key Configuration: Uses the expression ={{ $json.output }} for the message body.
Send a text message (Telegram n8n node): Function: Delivers the same CRO report to a specified Telegram chat. Key Configuration: Uses the expression ={{ $json.output }}.
Rapiwa (Custom n8n node): Function: Sends the analysis report to a WhatsApp number, completing the multi-channel notification component of the n8n workflow.
