A redesign keeps its rankings when every old URL that earned traffic or links redirects once to its closest new page, titles and content carry over, and indexing is checked after launch. Most losses come from deleted pages without redirects, a staging noindex left on after launch, or URL changes nobody mapped.
What should you do before the redesign?
- Crawl the current site and export every URL.
- Record the top pages by clicks in Search Console, and by traffic and conversions in GA4.
- List pages with backlinks, so you know which URLs must be protected.
- Keep URLs the same wherever a change brings no benefit.
- Save current titles, descriptions, headings and key content for the pages that rank.
How do you map the redirects?
Create a spreadsheet with the old URL, the new URL and the reason. Send each old page to its closest new equivalent with a single permanent (301) redirect, not to the home page. Where a page has no equivalent, choose the nearest category or topic page. Avoid chains where one redirect leads to another. Google’s documentation explains redirects and site moves.
What should you check on the staging site?
- The new pages keep the titles, headings and copy that rank.
- Internal links use the final URLs.
- Canonical tags point to the final URLs.
- Structured data, tracking tags and forms work.
- The staging site is blocked from search, and you know the block must be removed at launch.
What should you check on launch day?
| Check | Why |
|---|---|
| The staging noindex and robots block are removed | A leftover block keeps the new site out of Google |
| Redirects work on a sample of old URLs | Each should reach the right page in one step |
| The sitemap lists the new URLs and is submitted | It helps Google find the new pages |
| GA4, Search Console and conversion events are live | You need a baseline from day one |
| Key pages load quickly on a phone | New designs often add heavy scripts and images |
What should you monitor after launch?
- Search Console indexing and error reports for the first weeks
- Clicks and impressions for the pages you recorded before the move
- 404 errors, and add redirects for any old URL that appears
- Conversions on the new forms, calls and WhatsApp buttons
What if rankings have already dropped?
Find the pages that lost traffic, check whether they were redirected, compare old and new content, and look for noindex, canonical or robots mistakes. Our migration recovery case study shows a site that lost ranked pages and recovered. If you are planning a rebuild, our website development and technical SEO pages describe how we protect rankings.
What mistakes cost rankings most often?
- Deleting old pages without redirects
- Leaving a noindex or robots block on after launch
- Redirecting everything to the home page
- Changing URLs without a map
- Dropping the content that ranked from the new pages
- Launching without tracking
Who should own what?
- The marketer or SEO owns the URL map, content notes and monitoring.
- The developer owns redirects, canonicals, speed and the launch checklist.
- The business owner approves which pages stay, merge or go.
Frequently asked questions
Will a redesign hurt my Google rankings?
It does not have to. Rankings are usually protected when URLs are kept or redirected, content carries over, and the new site is fast and crawlable. Most drops come from preventable mistakes, such as missing redirects or a leftover noindex.
Should I redirect old pages to the home page?
No. Redirect each old page to its closest equivalent. Sending many pages to the home page loses relevance, and Google may treat the mass redirect as a missing page. Use the home page only when nothing else fits.
How long do redirects need to stay?
Keep them as long as the old URLs have traffic or links, which in practice means a year or more. Removing them early can bring back errors for visitors and for the links that point to the old addresses.
How long until rankings settle after a migration?
It varies with the size of the site and how cleanly the move was done. Expect some fluctuation for a few weeks. If key pages are still missing from the index or losing clicks after that, investigate.
