Description
Site Check reads a public website the way a browser, a search engine and an AI assistant would, and reports what it measured. It checks server speed and page weight, HTTPS, certificate and domain expiry, security headers, email authentication (MX, SPF, DMARC), title, description, indexability and sitemap, structured data, AI crawler rules and llms.txt, and whether a visitor can call or write. Every warning and failure comes with a plain fix and an effort level, and the site gets a 0 to 100 score built from the measured checks. No AI model judges anything. Ask for the AI search view to see which AI crawlers a site allows and whether answer engines can quote it. Give a business's Google rating and review count to get a local presence score across website, reviews and Google Business Profile. Facts that were not supplied are left out, never scored as zero. Read-only, no sign-in, public websites only. Results are cached for 24 hours.
