Search Console after a migration
By Ismael · Reviewed
Search Console after a migration is the measuring instrument: it shows which old URLs still earn impressions, which new URLs are indexed, and where the move has not finished. SiteBienfait keeps both properties verified through cutover. Google Search Central, updated 2026-08-20, recommends verifying every variant of both the old and new sites before a move starts.
What should be checked immediately after cutover?
Four checks. Both properties verified, including www and non-www and both protocol variants. The new sitemap submitted and the old one removed, as Google Search Central, updated 2026-08-20, describes. The old URLs returning permanent redirects to the matching new pages. The canonical tags on the new pages naming the new URLs, per Google Search Central’s canonical guidance updated 2026-07-10.
These are configuration facts, so they should be confirmed before looking at any chart. A wrong redirect is not a fluctuation.
When is Change of Address the right tool?
When the domain or subdomain changed. Google Search Central, updated 2026-08-20, limits the tool to that case and states it is not needed for HTTP to HTTPS moves, www to non-www changes or path changes within one domain. For a domain move, submit it for every verified variant of the old domain, even ones not actively used.
The tool moves the signal, but it does not replace redirects. Both belong in the cutover: redirects for the per-URL mapping, Change of Address for the host.
How long does the move take to show?
Longer than most site owners expect, and with no fixed schedule. Google Search Central, updated 2026-08-20, says a medium-sized site can take a few weeks or more for new URLs to replace old ones in results, that larger sites take longer, and that there is no fixed crawl frequency.
The same page defines completion: Googlebot must have visited every URL on the old and the new site at least once. Until then, the reports show a mixture, and a mixture is normal.
Which reports show progress?
Page indexing shows whether new URLs are indexed and whether old ones have dropped out. Sitemaps shows how many submitted URLs have been indexed. Performance shows queries, pages, clicks, impressions and average position — old and new pages can be compared by filtering on the page dimension.
For query-level analysis beyond the interface, the Search Analytics API, updated 2026-08-11, returns rows of clicks, impressions, CTR and average position for the dimensions requested. Average position is exactly that, an average across searchers and locations, not a fixed rank.
Ask Google to recrawl the pages that changed most, but do not repeat the request in a loop. Google Search Central’s recrawl guidance, updated 2025-12-10, treats the request as a hint, not a queue command.
What signals a real problem rather than normal fluctuation?
Temporary ranking fluctuation is documented and expected. The patterns that are not fluctuation are old URLs returning 404 instead of a redirect, redirect chains, new URLs blocked by robots or noindex rules left from staging, canonicals still naming old addresses, and pages that existed before with no replacement.
Also watch capacity. Google Search Central, updated 2026-08-20, notes that a new site is crawled more heavily after a move because old URLs redirect into it, so slow responses during the first week can compound indexing delays.
SiteBienfait’s migration route tracks these checks as part of the change set, then keeps monitoring after deployment. The redirect map checker verifies the URL mapping before the move, so the post-launch report only has to confirm what was already reviewed. The website migration SEO checklist lists the artefacts to have ready before this point.

Questions
01 What should be checked in Search Console right after a migration?
Verify every variant of both the old and the new property, confirm the new sitemap is submitted and the old one removed, and check that the old URLs redirect to the intended new URLs. Google Search Central, updated 2026-08-20, recommends verifying all variants before the move starts.
02 When should Change of Address be used?
Only for domain or subdomain changes. Google Search Central, updated 2026-08-20, states that HTTP to HTTPS moves, www to non-www changes and path changes within one domain do not need the tool.
03 How long does Search Console take to reflect a migration?
Google Search Central, updated 2026-08-20, says a medium-sized site can take a few weeks or more before new URLs replace old ones, and larger sites longer. There is no fixed crawl frequency; a move is complete when Googlebot has visited every URL.
04 Why do queries fluctuate after a migration?
Google states that ranking fluctuation is expected while the site is recrawled and reindexed. A drop that lasts days is different from new URLs returning 404, redirect chains or canonicals still pointing at old addresses.
