5. Quality Over Quantity : Substantial, valuable content ranks better than thin content. Aim for comprehensive pages.
6. Technical Foundation : Fix critical technical issues (missing tags, broken structure) before advanced optimization.
7. Structured Data : Schema markup helps search engines understand content and can lead to rich results.
8. Regular Updates : SEO is ongoing. Keep content fresh, monitor analytics, and adapt to algorithm changes.
9. Natural Language : Write for humans using natural language. Avoid keyword stuffing.
10. Validation : Always validate changes with testing tools before deploying to production.
