# SiteVitals > SiteVitals is a UK-based SaaS platform providing continuous website health monitoring across uptime, SEO & AI visibility, security, page performance, integrity & assets, and content change intelligence. Built by Lisa and Tom - a husband-and-wife team with over 25 years of web development experience - for businesses that don't have a full-time developer watching their site. SiteVitals monitors websites from the outside, the same way visitors and search engines do. Nothing is installed on the monitored site. All data is stored within the UK and EU. Every detection is logged to a shared, annotatable timeline - so when something goes wrong, users know exactly what changed and when. ## Features - [Uptime & Availability](https://www.sitevitals.co.uk/features/uptime): Continuous availability monitoring with instant email/webhook alerts, incident history, keyword presence checks, and smart false-positive verification. Checks run every 1–10 minutes depending on plan. - [SEO & AI Visibility](https://www.sitevitals.co.uk/features/seo-essentials): Technical SEO monitoring including metadata & canonical audits, JSON-LD schema validation, AI readiness scoring, AI crawler & llms.txt audits, indexing integrity, broken link detection, heading structure analysis, and social tag completeness. - [Security Monitoring](https://www.sitevitals.co.uk/features/security): Continuous checks on security headers (HSTS, CSP, X-Frame-Options), cookie & session flags, form injection vulnerabilities, mixed content, subresource integrity, software version disclosures, and browser-side risk profiling. - [Integrity & Assets](https://www.sitevitals.co.uk/features/integrity): SSL chain verification with expiry alerts, domain registration monitoring, broken asset detection (CSS, JS, images), mixed content alerts, and DNSSEC & DNS record audits. - [Change Intelligence](https://www.sitevitals.co.uk/features/change-intelligence): Content change monitoring using Jaccard Similarity and Levenshtein distance, external dependency fingerprinting, keyword drift tracking, structural mapping (H1/title changes), and a user-annotatable event timeline for logging deployments and edits. - [Page Performance](https://www.sitevitals.co.uk/features/performance): Core Web Vitals monitoring (LCP, CLS, INP), Lighthouse issue extraction, automated regression alerts (>5 point drops), render-blocking resource identification, unsized image detection, and third-party script analysis. ## Pricing All prices in GBP, excluding VAT.
