A website rebuild is exciting — right up until traffic collapses because the migration was mishandled. Losing rankings on launch is common and almost entirely avoidable. Here is how to move to a new site while protecting the SEO you have worked for.
Why migrations go wrong
Most SEO losses come from changed URLs with no redirects, lost content, or new technical problems. Google effectively loses track of your pages, and the rankings tied to them vanish. The fix is planning, not luck.
The migration checklist
- Map every existing URL and decide its new home.
- Set 301 redirects from each old URL to its new equivalent — this passes ranking value across.
- Preserve your best content, especially pages that already rank and earn traffic.
- Keep titles, headings, and structure for pages that perform.
- Submit the new sitemap in Google Search Console.
After launch
Crawl the new site for broken links and redirect errors, watch Search Console for coverage issues and ranking changes, and fix anything that slips. A brief dip can be normal; a sustained drop means something needs attention.
Do not rebuild blind
Before you change anything, record your current rankings, traffic, and top pages so you have a baseline to protect and compare against. Migrating is also the perfect moment to improve speed and structure — see SEO for B2B websites.
Frequently asked questions
Will I lose rankings when I rebuild?
Not if you map URLs, set 301 redirects, and preserve your best content. Most losses come from skipping these steps.
What is a 301 redirect?
A permanent redirect that sends an old URL to a new one and passes most of its ranking value across.
How long until rankings recover if they dip?
A short dip can settle within weeks. A lasting drop usually points to a fixable technical issue.
