Run a 10-point SEO audit and HTML report via webhook and HTTP request

Description

Quick overview This workflow exposes a GET webhook that accepts a website URL, fetches the page, runs a 10-point SEO checklist with a score out of 100, and returns a ready-to-share HTML audit report in the webhook response. How it works Receives a GET webhook request on the site-check endpoint with a url query parameter. Validates and normalizes the input to allow only public domain URLs (no IPs, localhost, or internal TLDs). Fetches the target page via an HTTP request using a custom User-Agent and an 8-second timeout. Parses the returned HTML to evaluate 10 checks (reachability/response time, HTTPS, title length, meta description, viewport tag, single H1, image alt text coverage, Open Graph image, HTML lang attribute, and page size) and computes a score out of 100. Builds a simple HTML report summarizing the score and pass/fail results for each check. Responds to the webhook with the generated HTML report and a text/html content type. Setup Activate the workflow and copy the production webhook URL for the site-check endpoint. Call the webhook with ?url=yourdomain.com (or ?url=https://yourdomain.com) and ensure the target site is publicly reachable from your n8n instance. Optionally adjust the scoring thresholds, checks, timeout, and User-Agent in the workflow code and HTTP request configuration to match your audit criteria. Requirements An n8n instance (Cloud or self-hosted). No credentials or API keys are needed. Customization Change thresholds or add checks in the "Audit & build report" Code node, send the report by email with a Gmail node, or log every checked domain in Google Sheets to collect leads.
