AI Website Answer Visibility Audit n8n Workflow (DataForSEO + OpenRouter + Gmail)

Run an AI website visibility audit and email the results—automatically

This n8n workflow performs an AI Website Answer Visibility Audit by checking crawl/access signals, validating on-page readiness with DataForSEO, verifying whether your site is mentioned in AI-style answers, then generating a plain-language AEO report via OpenRouter and sending it through Gmail.

What this workflow does

• Receives audit requests via an n8n Form Trigger (business details, website URL, location, test queries, and recipient email).
• Normalizes and validates inputs, limits test queries, and upserts submissions into an n8n Data Table for tracking.
• Checks crawl/access signals by fetching robots.txt, sitemap.xml, and llms.txt and assessing whether common AI crawlers are fully or partially blocked.
• Runs a DataForSEO On-Page API check to collect on-page readiness signals (e.g., structured data detection, headings, word count, missing image alt text, and render-blocking resources).
• Validates AI answer presence by splitting the request into one item per test query and using DataForSEO AI Optimization (LLM Mentions) to determine whether the site/domain is mentioned for each question.
• Generates a non-technical AEO report using OpenRouter (with fallback) for a short, plain-language summary of findings.
• Sends an HTML email via Gmail with key status indicators and logs outcomes back into an n8n Data Table.

Use cases

• SaaS operators and agencies: produce repeatable AI visibility audits for client websites.
• SEO/AEO teams: quickly identify whether crawl/access blocks and on-page gaps are impacting AI-style answers.
• Automation engineers: set up a production-ready reporting pipeline using DataForSEO + OpenRouter + Gmail.

Technical details

• Integrations: DataForSEO (On-Page API + AI Optimization “LLM Mentions”), OpenRouter chat model (with fallback), Gmail.
• n8n nodes used: set, code, merge, split out, gmail, and Data Table logging.
• Required setup: add DataForSEO API credentials and ensure both the On-Page and AI Optimization (LLM Mentions) endpoints are configured.
