A website migration can make a business faster, safer and easier to manage. It can also accidentally remove valuable content, break links and disconnect people from resources that have been referenced for years. The problem is rarely solved by adding one broad redirect after launch.
TwoSquares helps businesses plan and implement website migrations with content continuity, URL relevance and technical SEO in mind. We focus on preserving genuine user value, not manufacturing authority from abandoned domains. That means finding the pages people actually use, mapping them to appropriate replacements and checking the results after deployment.
What causes avoidable SEO losses during a migration?
Changed URLs without mapping. A new website publishes equivalent pages at different addresses, leaving old links returning errors.
Deleted content. Useful articles, documentation and downloadable files disappear because they do not fit the new design.
Redirecting everything to the homepage. A specific old research paper or product page leads to a generic destination that does not answer the visitor's request. Search engines may treat such redirects as irrelevant or as soft 404s.
Technical indexation errors. Launch settings leave noindex tags in production, canonical URLs point to old addresses or important pages are inaccessible to crawlers.
Broken internal navigation. Menus, breadcrumbs and content links continue to point to old domains or incorrect paths, creating unnecessary redirect chains.
Unreviewed ownership and rights. An acquired domain may contain material that the new owner is not entitled to republish. Technical migration cannot override copyright or permission requirements.
Our process
Inventory and baseline
We identify existing URLs from the live site, XML sitemaps, crawl data, analytics, server logs and available backlink reports. We prioritise user-facing content and file-level citations, not just pages attracting broad SEO metrics. Where data exists, we preserve a pre-migration record of organic landing pages, search visibility, key conversions and technical status.
Destination mapping
Every meaningful old URL receives a decision: keep it, move it to a genuinely corresponding page, preserve the original file where permitted or return an accurate missing-resource status. Mapping is an editorial decision as well as a technical one. A former project paper should not be redirected to a generic service offer simply because it has a strong backlink.
Implementation
We configure appropriate server-side permanent redirects for true moves, avoid needless chains, update internal links and ensure the new pages return the correct status. We also check robots rules, sitemaps, canonical tags, structured data, page speed and the accessibility of key content.
Verification and monitoring
After launch, we check high-priority old URLs, indexing reports, crawl errors, organic landing pages and conversion tracking. We review unexpected behaviour rather than declaring success solely because redirects return a 301 code. Google's site move documentation recommends clear URL mapping, server-side redirects and ongoing monitoring.
Acquired and expired domains need extra care
Not every old domain represents a genuine site move. If a site was operated by an unrelated organisation, purchasing its address does not mean that the new owner has acquired its publication, authority or reputation. Google warns against expired domain abuse, where an expired address is reused primarily to manipulate rankings with content offering little user value.
Our preference is to create substantive, appropriately attributed replacement resources for topics that naturally fit a new website. If an original PDF is missing, we do not invent a replacement document. If a former page is unrelated to the new publication, we do not pretend otherwise.
We discuss this approach in our digital preservation hub and research library.
SEO recovery after a failed redesign
Where a migration has already gone wrong, we compare the old and new URL inventories, find disappearing landing pages, inspect redirect behaviour and identify where important content was removed or changed. Recovery may include restoring relevant pages, fixing canonical tags, removing accidental crawl restrictions and improving internal linking.
A search recovery plan cannot guarantee a return to prior rankings or timescales. Search results depend on the quality and relevance of content, competitive conditions, crawling and indexing. We measure what changes, explain uncertainty and prioritise fixes supported by evidence.
FAQs
Does a 301 redirect pass all of a page's ranking value?
No. A permanent redirect tells search engines a resource has moved, but it does not force them to regard the new page as equivalent or retain every ranking signal.
Should all old URLs redirect rather than return 404?
No. Redirect pages with genuine replacements. Where material has been permanently removed and no appropriate successor exists, an accurate 404 or 410 may be better than a misleading redirect.
Can this help if my website has already been deleted?
Yes, but recovery begins with evidence of the former content. Our website restoration service addresses the reconstruction of missing pages and assets.
How long should redirects remain in place?
Google generally recommends maintaining site-move redirects for at least a year, and longer where people still use old links. For important legacy citations, keeping an appropriate redirect indefinitely may be sensible.
