Description
Description An AI-powered workflow that analyzes any website to identify missing pages that would improve user experience and business performance. Submit a URL, and the system detects existing pages, researches competitors using Perplexity, and generates a professional gap analysis report with prioritized recommendations—saved directly to Google Docs. What this workflow does This automation delivers a complete website page gap analysis: Smart page detection:** Automatically scans website HTML and identifies 15 common page types (About, Contact, Services, Blog, Portfolio, Pricing, FAQ, Testimonials, Team, Careers, Privacy, Terms, etc.) Business type classification:** Determines if the site is ecommerce, portfolio/agency, blog, SaaS, or service-based to tailor recommendations Competitor research:** Uses Perplexity to research 5-7 top competitors in the same industry and identify their page structures AI gap analysis:** GPT-4.1-mini with web search compares the website against industry standards and competitor best practices Prioritized recommendations:** Generates High/Medium/Low priority suggestions with business value explanations and actionable content ideas Google Docs report:** Saves a professional gap analysis report ready to share with clients or stakeholders Setup requirements Tools you'll need: Active n8n instance (self-hosted or n8n Cloud) Google Docs with OAuth access OpenAI API key (GPT-4.1-mini access with web search) Perplexity API key (for competitor research) Estimated setup time: 15–20 minutes Step-by-step setup 1. Connect Google Docs In n8n: Credentials → Add credential → Google Docs OAuth2 API Complete OAuth authentication Create a new Google Doc for storing reports (or use an existing one) Open "Save Report to Google Docs" node Paste the Google Doc URL in the documentURL field 2. Add OpenAI API credentials Get API key: https://platform.openai.com/api-keys In n8n: Credentials → Add credential → OpenAI API Paste your API key Open "OpenAI GPT-4.1 Mini with Web Search" node Select your OpenAI credential Ensure model is set to gpt-4.1-mini Verify Web Search is enabled in the built-in tools section 3. Add Perplexity API credentials Get API key: https://www.perplexity.ai/settings/api In n8n: Credentials → Add credential → Perplexity API Paste your API key Open "Perplexity Competitor Research Tool" node Select your Perplexity credential 4. Share the form URL Open "Submit Website URL for Analysis" node Copy the Form URL from the node settings Share this URL with anyone who needs to run website audits The form accepts a single field: Website URL 5. Test the workflow Open the Form URL in your browser Enter a test website: https://example.com Submit the form Wait 30-60 seconds for the analysis to complete Check your Google Docs—the gap analysis report should appear Verify that: Existing pages are correctly detected Business type is identified Competitor research is included Recommendations are prioritized and actionable 6. Activate the workflow Toggle the workflow to Active at the top The form will now accept submissions 24/7 Each submission generates a new report appended to your Google Doc How it works 1. URL submission via form User opens the form link and submits a website URL they want to analyze. The form triggers the workflow immediately. 2. HTML fetch and extraction The workflow sends an HTTP request to the submitted URL and retrieves the complete HTML source code of the website's homepage. 3. Automated page detection A code node analyzes the HTML to detect 15 common page types: Navigation pages:** Home, About, Contact, Services, Products Content pages:** Blog, Portfolio, Pricing, FAQ Social proof pages:** Testimonials, Team, Careers Legal pages:** Privacy Policy, Terms of Service The detection works by: Scanning all internal links in the HTML Matching URL patterns (e.g., /about, /contact-us, /services) Searching for navigation keywords in anchor text Normalizing URLs (removing query params, anchors, trailing slashes) 4. Business type classification The code also identifies the website's business type based on HTML content patterns: Ecommerce:** Detects shopping cart, checkout, product pages Portfolio/Agency:** Identifies portfolio, case studies, creative work Blog/Content site:** Finds blog posts, articles, news sections SaaS/Software:** Detects subscription, cloud platform, software keywords Service/Agency:** Identifies consulting, marketing, agency services General:** Default if no specific patterns match 5. Deep competitor research with Perplexity The AI Agent instructs Perplexity to: Crawl the target website thoroughly (navigation, footer, hidden menus) Research 5-7 top competitors in the identified business type Document each competitor's page structure Identify industry-standard pages that successful sites consistently have Perplexity focuses only on user-facing pages and ignores technical files (sitemap.xml, robots.txt, admin pages). 6. AI gap analysis and recommendations GPT-4.1-mini with web search: Compares the website's existing pages against competitor structures Identifies genuinely missing pages (cross-references with detected existing pages) Prioritizes recommendations based on business impact (High/Medium/Low) Provides specific business value explanations for each recommendation Suggests actionable content for each missing page Includes competitor examples showing how others use these pages Critical filtering rules: Never recommends pages already detected Excludes technical files and admin pages Only suggests pages with clear business value Each recommendation must be justified 7. Professional report generation The AI Agent outputs a structured report containing: Website Overview:** URL, business type, analysis date Pages Confirmed as Existing:** Formatted list of detected pages Gap Analysis Summary:** Total pages analyzed, existing vs. missing count Recommended Pages to Add:** Detailed recommendations with priority, business value, content suggestions, and competitor examples Implementation Priority Summary:** Quick-reference lists by priority level Next Steps:** 2-3 actionable implementation steps 8. Save to Google Docs The complete report is inserted into your Google Docs document. Each new analysis appends to the same document, creating a running archive of all audits performed. Key features ✅ Automatic page detection: Scans HTML and identifies 15 common page types without manual input—no need to know the site structure beforehand ✅ Business type intelligence: Classifies websites into 6 business categories to provide industry-relevant recommendations ✅ Perplexity-powered research: Deep competitor analysis covering 5-7 top sites in the same niche with complete page inventories ✅ Smart filtering: Never recommends pages that already exist, even if they use different naming conventions or URL structures ✅ Priority-based recommendations: Every suggestion labeled High/Medium/Low with clear business justification—know what to build first ✅ Actionable content ideas: Not just "add a blog"—specific suggestions for what content should go on each recommended page ✅ Competitor examples: See how successful competitors use each recommended page type in their own sites ✅ Google Docs integration: Professional reports saved automatically—no downloads, no formatting, ready to share ✅ Form-based workflow: Single URL submission—anyone can run audits without touching n8n Troubleshooting HTML fetch fails SSL certificate issues:** Some websites block automated requests. Try adding "rejectUnauthorized": false in HTTP Request options. Cloudflare/bot protection:** Sites with aggressive protection may block the request. Test with a simple site first (like your own). Timeout errors:** Increase timeout setting in HTTP Request node to 30-60 seconds for slow-loading sites. Pages not detected correctly Non-standard URL structure:** The workflow detects pages using common patterns (/about, /contact, etc.). If a site uses unusual URLs like /company-info instead of /about, manual review may be needed. Single-page websites:** Sites built as SPAs (single-page applications) with JavaScript routing may not have distinct page URLs in HTML. The workflow works best with traditional multi-page sites. Check detection details:** The code node outputs detection_details showing exactly what was found. Review this to debug false negatives. Perplexity API errors Rate limits:** Perplexity has usage limits. If you hit them, wait or upgrade your plan. API key invalid:** Verify the key is correct at https://www.perplexity.ai/settings/api Quota exceeded:** Check your Perplexity dashboard for remaining credits. OpenAI web search not working Web search disabled:** Ensure "Web Search" is enabled in the OpenAI Chat Model node under "Built-in Tools" Search context size:** Set to "Medium" for balanced performance Model compatibility:** Web search only works with GPT-4 models, not GPT-3.5 Report not saving to Google Docs Re-authenticate OAuth:** Go to Credentials → Google Docs OAuth2 API → Reconnect Document URL format:** Ensure the URL is a valid Google Docs link (not a folder or Sheets link) Permissions:** Verify the connected Google account has edit access to the document Document locked:** Check if the document is open in another tab with unsaved changes AI recommendations are too generic Perplexity research quality:** The AI relies on Perplexity's research. If competitors have similar structures, recommendations may overlap. Try analyzing a more unique website. Business type misclassification:** Check the detected business_type in the code output. If it's wrong, the recommendations will be off-target. Improve prompt:** Edit the AI Agent system prompt to emphasize more specific or creative recommendations for your niche.
