Move to a modern stack without losing your rankings

Most DIY migrations lose SEO equity not because of bad intentions but because the redirect work is incomplete. A 301 redirect chain where the old URL redirects to an intermediate URL before reaching the final destination passes less PageRank than a direct mapping. Canonical tags left pointing to the old domain tell Google that the new pages are duplicates of content that no longer exists. XML sitemaps submitted to Search Console listing old URLs that now 404 — rather than the new canonical URLs — slow down the re-crawl process by weeks. Each of these errors individually is recoverable. Combined across hundreds of pages, they produce the traffic drops that teams notice two months after launch and spend another six months diagnosing.

The pre-migration crawl is the foundation of a safe migration. Using a tool like Screaming Frog or Sitebulb, we catalogue every URL currently indexed — including orphan pages, PDFs, image assets with inbound links, and parameter-based URLs that analytics has been counting as separate pages. Without that complete inventory, any redirect mapping is guesswork. The crawl also surfaces existing 404s, redirect chains, and canonicalisation issues that need to be resolved before the migration begins, not discovered mid-transfer.

Post-migration monitoring is a defined period of active observation, not an optional follow-up. In the first 30–60 days, the Search Console coverage report shows how quickly Google is discovering and indexing the new URLs. 404 tracking through log file analysis identifies URLs that were missed in the redirect mapping before they accumulate enough crawl budget waste to affect rankings. Ranking position checks against a pre-migration baseline reveal which keyword groups need attention. Rushing a migration to hit a launch deadline is the single most common cause of organic traffic loss — the redirect mapping cannot be done well in a compressed timeframe, and the consequences take months to reverse.
