SEO Checklist Before Redesigning an Existing Website

Redesign decisions about URLs, templates and content can permanently change search signals if old pages disappear without a plan.

Inventory before deleting

Export existing URLs from a crawl, sitemap, Search Console and analytics where accessible. Identify pages with meaningful links, traffic or enquiries.

A URL with little visible traffic may still contain useful reference information or incoming links.

Map new equivalents carefully

Keep valuable URLs when possible. If a page genuinely moves, use a permanent server redirect to its closest relevant new page. Redirect chains and blanket homepage redirects are avoidable weaknesses.

Keep new page titles and content purpose aligned with the historic search intent unless the business has deliberately changed its offering.

Test launch conditions

Check robots rules, canonical tags, XML sitemap, mobile navigation, assets, forms if any, status codes and redirect targets in a staging environment. Avoid accidentally indexing staging sites.

Monitor key URLs and crawl errors after release; explain expected temporary movement without claiming zero risk.
