Redesign without erasing what works

A website redesign should preserve valuable assets, fix proven problems, and migrate URLs, measurement, and content through a verifiable plan.

Risks a visual review does not catch

Starting with new screens hides SEO, form, integration, and content risks. Errors appear after launch when they cost more.

How to migrate content, SEO, and measurement

Create a baseline for traffic, conversions, URLs, and performance. Define acceptance criteria for every template before development.

Implementation checklist

  • Inventory pages, rankings, links, and conversions.
  • Decide what to keep, merge, update, or remove.
  • Map redirects and metadata before development.
  • Test forms, events, accessibility, and speed.
  • Monitor errors, indexing, and conversion after launch.

The prelaunch review should also check performance and accessibility.

Protect what already works

Before redesigning, export URLs, traffic, conversions, and queries. That baseline prevents valuable pages from being removed because they look old.

Decide whether every URL stays, improves, redirects, or retires. Building the map after launch creates avoidable errors and losses.

Test forms, analytics, accessibility, and redirects in staging. A visual review covers only part of the risk.

Checks before launch

  • A URL inventory and map.
  • Content and measurement backups.
  • Critical-task tests.
  • A post-launch monitoring plan.
