What needs to be ready before launch
- Export and review existing URLs
- Plan redirects for changed paths
- Check titles, descriptions, headings and canonicals
- Align sitemap, robots.txt and 404 behavior
- After launch, monitor crawling, indexing and error pages
Why SEO belongs in planning
If redirects or metadata are discovered at the end, a relaunch becomes unnecessarily risky. That is why SEO belongs in the analysis and planning phase.
