How to Migrate a Website Without Losing SEO (2026)
To migrate a website without losing SEO: export every indexed URL first, map old URLs to new ones, implement 301 redirects, preserve titles and content depth, launch on a staging environment, then monitor Search Console daily for four weeks. Budget one to four weeks.
Traffic collapse after a migration is almost always caused by one omission: nobody recorded what the old site's URLs were. That export costs nothing and is the single most valuable artefact in the whole project.
The steps
- 1
Export every URL before you touch anything
Pull all indexed URLs from Search Console, all ranking pages from analytics, and crawl the live site with Screaming Frog. Save this. Once the old site is gone, reconstructing what existed is guesswork, and guesswork is how rankings disappear.
- 2
Identify what actually earns traffic
Sort your pages by organic sessions and rankings. Typically 20–30% of pages drive nearly all the value. Those must migrate with URLs and content intact; the rest can be consolidated or removed with redirects.
- 3
Keep URLs identical wherever possible
The safest migration changes no URLs at all. Every URL change is risk you are choosing to take. If the new structure genuinely improves things, change them — but do it deliberately, not as a side effect of a new CMS's defaults.
- 4
Build a complete redirect map
Every old URL needs a 301 to its closest new equivalent — not all to the homepage, which Google treats as a soft 404. Map them individually for important pages and by pattern for the long tail. This is the step most often rushed and most often regretted.
- 5
Preserve titles, headings and content depth
A redesign that cuts a 1,500-word page to 300 words will lose rankings even with perfect redirects. Keep the substance. Improve presentation, not the amount of information available.
- 6
Test on staging with the redirect map applied
Crawl the staging site, check every redirect resolves in one hop, confirm canonicals and check nothing is accidentally noindexed. A staging robots.txt blocking crawlers that ships to production is a classic and catastrophic error.
- 7
Monitor daily for four weeks after launch
Watch Search Console coverage, crawl errors and impressions, and analytics for organic sessions. Expect a small dip for one to two weeks. A sustained drop past three weeks means something is wrong — usually a redirect gap you can still fix.
Common mistakes
Map each URL to its closest equivalent. Bulk homepage redirects are treated as soft 404s and pass almost no value.
Check robots.txt and meta robots on production immediately after launch. A blocked site can lose visibility within days.
Preserve information depth on pages that rank. Redesign the presentation, not the substance.
Export from Search Console before starting. Without it, diagnosing a traffic drop becomes guesswork.

Frequently asked questions
How long does it take to recover rankings after a migration?
A well-executed migration shows a small dip for one to two weeks and recovers fully within four. If rankings have not recovered after six weeks, something structural is wrong — usually missing redirects, blocked crawling or lost content depth.
Should I change URLs during a redesign?
Only if the new structure is genuinely better and you are prepared to build a complete redirect map. Keeping URLs identical eliminates most migration risk. 'The new CMS prefers this format' is not a good enough reason to accept the risk.
What does a website migration cost in India?
₹30,000–₹1,50,000 for the SEO side — URL mapping, redirect implementation, testing and monitoring — on top of the build cost. It is the line item most often cut from redesign budgets and the one whose omission is most expensive.
Do I need to resubmit my sitemap after migrating?
Yes. Submit the new sitemap in Search Console immediately after launch, and keep the old sitemap accessible briefly so Google can discover the redirects. Use the Change of Address tool if you are moving to a different domain.
