Before a redesign, record important URLs, rankings, backlinks, traffic, conversion events and form journeys. This baseline helps the team spot real regressions after launch.
Preserve high-value page intent even when the design changes. Map old URLs to the closest relevant replacements, retain useful copy and metadata, and avoid removing pages that still meet a genuine search need.
Launch is the start of monitoring, not the end of the project. Check crawling, redirects, forms, analytics, page speed and lead quality during the first weeks so issues are fixed while evidence is fresh.
