Which pages and SEO metrics should be audited and benchmarked before redesign work begins?

How to Plan a Website Redesign Without Losing Your SEO Rankings means benchmarking organic traffic, impressions, clicks, ranking pages and queries, backlinks, conversions, landing pages, and indexed URLs before work starts. Check broken links, duplicate content, missing metadata, page speed, rankings, internal links, redirects, XML sitemaps, and indexation.
Export Search Console query- and URL-level data covering at least to months, then save a dated ranking report for later comparison. Document analytics goals, event tracking, attribution, integrations, business metrics, and Core Web Vitals baselines so post-launch changes can be measured accurately.

How can you identify the highest-value pages to prioritize during a redesign using the/20 principle?
High-value pages are protected assets when they produce meaningful organic traffic, conversions, backlinks, or strong rankings for commercially relevant terms. How to Plan a Website Redesign Without Losing Your SEO Rankings by ranking these pages before you rank pages by appearance or template convenience.

Preserve the structure and substance of must-save pages unless evidence supports a change, and review pages with no traffic before deciding whether they are necessary. Include backlinks, especially pages with the most dofollow links, because an unimpressive page may still be valuable externally. How to Plan a Website Redesign Without Losing Your SEO Rankings by treating those findings as a prioritized migration queue.

Test redirects thoroughly, monitor errors, and keep them live for at least a year after launch.

How to Plan a Website Redesign Without Losing Your SEO Rankings should preserve what works before changing what can be measured.
