Website Migrations We Plan and Protect
Every migration changes something search engines rely on, whether URLs, templates, content or servers. Knowing which type of move you are making tells us where the biggest risk sits and how much planning it needs.
| Migration type | Typical example | Main SEO risk |
|---|---|---|
| Website redesign | New theme and page layouts | Lost content, headings and internal links |
| Platform migration | WordPress to Shopify, or Magento to BigCommerce | New URL structure and missing redirects |
| Domain change | Rebrand to a new domain name | Authority transfer and Search Console setup |
| HTTPS migration | HTTP site moving to HTTPS | Mixed redirects and duplicate versions |
| URL structure change | New folders or cleaner slugs | Broken links and redirect chains |
| Merger or consolidation | Several sites combined into one | Overlapping pages and lost backlinks |
| Hosting migration | New server or CDN | Downtime, speed changes and blocked crawlers |
Many projects combine several types, such as a rebrand with a new domain, new platform and design. Combined moves carry the highest risk, so we plan them earlier and monitor them longer than simple changes.
Why Rankings Drop After a Website Migration
Traffic drops after launch are common but rarely mysterious. Almost every loss traces back to a short list of preventable mistakes, which a migration SEO plan exists to catch before your new website goes live.
Missing or Chained Redirects
Old URLs without a 301 redirect return a 404 error and lose their backlinks, while redirect chain and redirect loop problems slow crawling and leak link equity, especially when earlier redesigns left old redirects behind.
Lost Content and Metadata
Designers often trim copy, merge pages or drop title tag and meta description details during a redesign. Without content parity checks, pages that ranked well can lose the text and headings that earned those rankings.
Blocked or Noindexed Pages
A staging site setting copied to production, such as a robots.txt block or sitewide noindex tag, can remove a whole website from search within days. We check these settings at launch and again soon afterward.
Broken Tracking and Internal Links
Missing GA4 tags make losses invisible, while internal links still pointing at old URLs force extra redirect hops. Both problems are easy to miss on launch day unless someone checks them against a written checklist.
Our Three-Phase Migration SEO Process
Migration SEO starts long before launch day and continues for weeks afterward. Each phase has its own checklist and owner, so nothing depends on memory during the busiest, most stressful part of the whole project.
Pre-Launch Planning
We record a traffic and ranking baseline, build a URL inventory from crawls, analytics and backlinks, map each old URL to its closest match, and review the staging site for content parity and technical issues.
Launch Day
Our technical SEO team tests redirects in bulk, checks robots.txt, canonical tags, noindex rules and XML sitemaps, confirms tracking works, submits sitemaps in Search Console and uses the Change of Address tool for domain moves.
Post-Launch Recovery
We monitor crawl errors, index coverage, rankings and organic traffic daily at first, then weekly, fixing any missed redirects and broken links quickly, because early fixes shorten the recovery period after any website migration significantly.
Planning a Redesign or Platform Change?
Book a free migration snapshot before you launch. We will crawl your current site, list the pages carrying the most traffic and backlinks, and flag the risks we see in your plans and staging site.
Deliverables You Receive Before Launch Day
Migration planning produces documents your developers can follow and your managers can sign off. Each one is shared in an editable format, so your team keeps full ownership of the plan before and after launch.
- Complete URL inventory from crawls, analytics and backlinks
- Redirect map pairing every old URL with its new URL
- Metadata and content parity sheet for priority pages
- Staging site crawl report with issues and owners
- Launch-day checklist with tests and responsibilities
- Rollback plan agreed with your development team
- Tracking checklist for GA4, tags and conversions
The redirect map matters most in any migration. We build it page by page for priority URLs and with tested rules for large sets, so valuable pages send visitors and authority to the right place.
Migration SEO Timelines by Website Size
Planning time grows with page count, platform complexity and the number of changes happening at once. These ranges help you schedule SEO support early enough, rather than inviting it in during the final launch week.
| Website size | Planning before launch | Monitoring after launch |
|---|---|---|
| Under 100 pages | Two to three weeks | Eight weeks |
| 100 to 2,000 pages | Four to six weeks | Ten to twelve weeks |
| Large ecommerce or enterprise | Eight weeks or more | Twelve weeks or more |
Google advises keeping redirects in place for at least a year after a site move, and we recommend keeping them much longer wherever technically possible. See Google's site move guidance for the full official recommendations.
Already Migrated and Lost Traffic? How We Recover It
If the new website already launched and organic traffic fell, recovery is often still possible. Speed matters, because search engines settle on the new structure over time, and missing redirects lose more value every week.
Find What Broke
We compare old URL lists from backups, analytics and backlink tools with the live site, find pages returning 404 errors or wrong redirects, and check content parity, indexing and tracking against the original pre-launch baseline.
Restore Equity Quickly
Missing redirects are added first, then lost content and metadata are restored on priority pages, internal links are updated and sitemaps resubmitted, so rankings can begin recovering within weeks instead of drifting lower for months.

Tell us what is changing, your planned launch date and platform, and we will review your current site, highlight the pages with the most to lose and outline a migration plan sized to your project.
The earlier SEO joins, the cheaper protection becomes. Many clients pair this with a full SEO audit of the old site, so existing problems are fixed during the move instead of being carried across unnoticed.

Website Migration SEO FAQs
What is website migration SEO?
Website migration SEO is the planning, testing and monitoring that protects search rankings when a website changes its URLs, platform, domain, design or hosting. It focuses on redirects, content parity, technical settings and accurate tracking.
Will I lose rankings when I migrate my website?
Some short-term movement is normal while search engines process changes. With a complete redirect map, content parity and careful launch checks, most well-planned migrations keep their rankings and recover small dips within a few weeks.
How long does it take to recover after a migration?
Well-planned migrations often stabilize within a few weeks to two months. Domain changes and large platform moves can take longer, because search engines must recrawl and reprocess many URLs before fully trusting the new structure.
How long should 301 redirects stay in place?
Google recommends keeping redirects for at least one year after a site move, and longer is safer. Old URLs keep receiving visits from backlinks, bookmarks and emails for years, so we advise keeping redirects permanently.
When should SEO get involved in a website redesign?
Ideally during planning, before designs and URL structures are approved. Early involvement keeps important content, URLs and internal links intact, and it is far cheaper than repairing lost traffic after the new site launches publicly.
Can you help migrate my site to Shopify or WordPress?
What is a redirect map?
A redirect map is a spreadsheet listing every old URL beside its new destination and redirect type. It guides developers during launch, then becomes the checklist used to test that every important page redirects correctly.
Can you recover traffic after a migration that went wrong?
Often, yes. We find missing redirects, lost content, blocked pages and broken tracking, then fix the highest-value problems first. Recovery is faster the sooner work begins after the traffic drop first appears in your reporting.
