What have we created?
I have developed an automated workflow in n8n that allows users to interact via Telegram with a technical SEO expert agent. This agent can automatically detect whether a website has a canonical tag configured and provide detailed information about it.
Technologies used
- N8n: Workflow automation platform
- Telegram: Conversational user interface
- Gemini: AI model for natural language processing
- JavaScript: Logic for HTML analysis
- HTTP requests: Web content extraction
First phase: Intelligent conversational agent
The core of the system is a specialized conversational agent that:
Acts as a technical SEO expert: Configured with a specific prompt to behave like a professional in technical SEO
Requests URLs from the user: Naturally asks for the website URL to analyze
Integration with Gemini: Connected to the Gemini AI model for natural language processing
Persistent memory: Maintains conversation context, remembering provided URLs and past interactions
Specialized tool: Implements a tool that activates automatically when a user provides a URL, storing it for later processing
Second phase: Processing and analysis
The workflow includes an intelligent decision system:
Evaluation condition
Determines whether the user has provided a valid URL in the conversation
If no URL: The conversation continues with the agent requesting the necessary information
If there is a URL: The process proceeds to the technical analysis phase
Content extraction
An HTTP request module retrieves all the HTML code from the provided URL
This process is fully automated and handles different types of server responses
Code analysis:
A specialized JavaScript code node examines the HTML for the canonical tag
The analysis is thorough and considers different formats and tag locations
Third phase: Response to the user
The system ends with a clear and helpful response:
If it finds the canonical tag
Confirms its presence
Provides the exact canonical URL
Offers relevant additional information
If it does not find the tag
Clearly states that no canonical tag exists
Can suggest improvements or next steps
System benefits
This automated workflow offers multiple advantages:
- Accessibility: Users can perform SEO audits from Telegram without complex technical tools
- Speed: Instant analysis of any URL
- Accuracy: Precise detection of canonical tags in various formats
- Scalability: Can handle multiple simultaneous queries
- Contextual memory: Maintains conversation thread for deeper analysis
Practical applications
This system is especially useful for:
- SEO auditors: Quick verification of multiple websites
- Web developers: Validation during development
- Marketing teams: Monitoring the SEO health of their digital properties
- Consultants: Demo and analysis tool for clients
