Sitevitals Monitor

Sitevitals Monitor is a website and server monitoring service focused on catching changes and failures early. It presents a single timeline for uptime, performance, security, SEO, servers, and scheduled jobs, with the aim of showing what broke, what changed, and what is drifting before a client notices.

The service groups its monitoring into several areas. Uptime checks run around the clock and can send instant email and webhook alerts. It includes smart verification intended to reduce false positives, keyword presence checks for database health, and a full incident history with recovery logs. For site integrity, it lists SSL chain verification and expiry alerts, domain expiry monitoring, broken asset detection for CSS, JavaScript, and images, mixed content alerts, and DNSSEC and DNS record audits. Its SEO and AI visibility checks cover metadata, canonical tags, heading structure, block-level schema validation, AI readiness scoring for sameAs, speakable, and FAQ, llms.txt and AI crawler access checks, indexing and robots.txt integrity, broken internal and external links, and Open Graph and X Card validation. Performance monitoring includes Core Web Vitals, Lighthouse scores, render-blocking resource detection, third-party script analysis, image and layout-shift forensics, and automated regression alerts for drops greater than five points. Security checks include HSTS, CSP, and X-Frame-Options validation, cookie audits for HttpOnly, Secure, and SameSite, CSRF and submission-method checks, mixed content and Subresource Integrity monitoring, exposed server signatures and version disclosures, and software vulnerability matching using the NVD database. It also includes a diff engine for live sites, with weighted change indexing and alerts for changes in titles, headings, keyword drift, semantic similarity, external dependencies, image count, and page weight.

The page describes the product as being for everyone responsible for a website, including developers, marketers, and people who have inherited a site. It says the interface offers technical detail when needed and plain-English guidance when only the next action matters. Sitevitals Monitor is accessed on the web, and it offers a free plan with no credit card required. Setup is described as taking 60 seconds, and the service says it is UK- and EU-based and privacy-focused.
