What problem does it solve? On-page SEO elements like titles, canonicals, schema markup, and robots directives can silently change during deployments or content edits, causing traffic loss that goes unnoticed for weeks. This Skill captures baselines of SEO-critical elements and alerts you when something drifts. ## Core Features & Use Cases - Baseline Capture: Snapshot title tags, meta descriptions, canonicals, robots directives, headings, JSON-LD schema, Open Graph tags, Core Web Vitals, and HTTP status codes into a local SQLite store. - 17-Rule Comparison Engine: Diff current page state against baselines with findings classified as CRITICAL, WARNING, or INFO, each with recommended actions. - CI/CD Integration: Run non-interactive checks across many URLs with configurable severity thresholds, JUnit XML reports, and exit codes that fail pipelines on regression. - Use Case: Before a deploy, run a baseline on your key pages; after the deploy, run a compare to instantly catch a dropped canonical tag or an accidentally added noindex directive. ## Quick Start Ask the assistant to capture an SEO baseline for your homepage URL, then later ask it to compare the page against that baseline to detect any SEO drift.
