4. Optimize URL Structure and Permalinks:

- Identify top-performing content, monitor search rankings, and address any issues or drops in performance.
- Regularly review and update your SEO strategy based on the insights gathered.

7. Implement Structured Data and Schema Markup:

10. Stay Up-to-Date with WordPress and Plugin Updates:
