Why do some pages never recover their rankings post-migration?

Because something that held the page’s ranking did not make it across: the redirect, the content, the internal links, or the page’s fit with the query. A migration does not pick pages at random to lose. When one page stays down after the rest of the site has settled, the cause is likely on that page, though a competitor or a change in the query can also be involved, and the place to start is comparing the old version with the new one.

Four places the signal gets lost

Cause What to check Recoverable?
The redirect The old URL returns an error, redirects temporarily, chains, or points to a page that does not cover the same content Yes: fix the redirect to a single permanent hop to the true equivalent
The content The new page is shorter, merged with other topics, or now answers a different question Yes, if the content that ranked is restored or rebuilt
Internal links The page lost menu, category or related links in the new templates and now sits deeper in the site Yes: restore links from the pages that used to point to it
Fit with the query The page was already marginal, and the move removed a small advantage; or the results for its query have changed Sometimes; the page may need to become a better answer than it was

Google’s site-move guide covers the first and third rows directly: it asks for each old URL to map to its corresponding new URL and for internal links on the new site to use the new addresses. The second row is the one teams miss, because the URL survived and the page looks fine, but the version that ranked no longer exists.

Compare old and new, page by page

For each page that has not come back, pull its old version from a pre-migration crawl or an archive and set it beside the new one:

  1. Does the old URL redirect once, permanently, to this page?
  2. Does this page cover what the old one covered, for the same queries?
  3. Do the pages that linked to it before still link to it now?
  4. Do the queries it used to rank for still show the same kind of results?

Pages that fail one of the first three have a fix. Pages that pass all three and fail the fourth face a changed field rather than a migration fault, and the decision is whether to improve them or let them go. The rest of the site follows its own settling timeline, described in how long to expect a traffic dip after a migration. Trace what the page lost before deciding it cannot recover.
