9. SEO, Schema & Accessibility
This module connects theme-level decisions (markup, navigation, layout) to outcomes you can measure: crawlability, structured data quality, accessibility, and Core Web Vitals.
What You'll Be Able To Do
- Audit and fix common markup issues (headings, landmarks, navigation)
- Choose a schema strategy and validate JSON-LD output
- Add practical accessibility improvements that survive theme changes
- Reduce SEO-impacting performance bottlenecks with a repeatable QA loop
