Redesigns and migrations without losing traffic

How to change your SaaS site's platform, domain or URLs without losing search traffic: the redirect map, the pre-launch checks and what to watch after.

This guide shows you how to plan a redesign or migration with a redirect map and a launch checklist.

Redesigns and platform moves are one of the most common reasons SaaS sites lose search traffic. The cause is rarely the design; it is URLs that change without redirects, content that disappears, and settings like noindex carried over from a staging site.

Short on time? Comppound does this work for SaaS companies. AI-native, and a person reviews every page.

Have us do it

Inventory before you change anything

Export every URL that gets traffic, has links or is in the sitemap. Record each one's title, main content and performance. This is your baseline and your checklist.

Build the redirect map

Map every old URL to its new equivalent with a permanent redirect. Where a page is being removed, redirect to the closest relevant page, not the homepage. Avoid chains of redirects.

Check before launch

On the staging site, check:

  • Staging is blocked from indexing, and the block will be removed at launch
  • Titles, descriptions and headings carried over
  • Canonical tags point to the new live URLs
  • Structured data still valid
  • Important text renders in the HTML

Watch after launch

Test the redirect map on the live site, submit the new sitemap, and watch Search Console for errors and drops daily for the first weeks. Some fluctuation is normal; sustained drops on specific pages point to a missed redirect or lost content.

Common mistakes

Redirecting everything to the homepage

Search engines may treat mass homepage redirects as soft 404s. Map each page to its closest equivalent.

Launching with noindex

Staging settings carried to live can remove a site from search. Check on launch day.

Dropping content in a redesign

Removing text from pages that ranked removes what they ranked for.

Questions

It varies. A clean migration may show little change; one with missed redirects can take much longer to recover.

Doing one change at a time makes problems easier to find.
