SAGE weights categories by impact, including Structured Data, Machine Readability, and Technical SEO, giving you a score that reflects real-world search and AI visibility factors. Letter Grades Letter grades from A through F make results instantly understandable. Actionable Fix Recommendations Every failing check comes with a specific fix: what to change, why it matters, and which pillars it affects. Fixes are tagged by impact so you can prioritize high-value improvements first. Schema Generator SAGE detects your page type, including Article, FAQ, Product, Local Business, SaaS, and Homepage, then generates ready-to-use JSON-LD structured data. Supports FAQPage, HowTo, Article, Product, LocalBusiness, SoftwareApplication, WebSite, and more.
