- 6,028 stable permanent redirects are safe to archive and suppress from routine crawling.
- 14 homepage-target redirects need review — they may indicate lost page-level mappings.
- 47 redirect chains add hops; collapse them to single 301s to preserve link equity.
The problem
Site migrations create overlapping URL sets, redirect chains, missing metadata, noindex mistakes, old internal links, and temporary capacity pressure right when teams need the clearest view.
The outcome
Crawle treats a migration as a monitored workflow: detect likely moves, confirm ownership, keep old redirects under watch, prioritize new targets, and archive stable old URLs when cleanup is safe.
- Migration candidates from redirect volume, target concentration, and path-preservation signals.
- Verified target-domain gating before Crawle broadly expands a new external domain.
- Old-source and new-target URL states for migration QA.
- Redirect mapping, broken migration redirect, target issue, and cleanup preview exports.
- Migration cleanup archives stable old redirects instead of silently deleting history.
Workflow
From crawl signal to team action
01
Detect the pattern
Crawle surfaces likely migrations when redirect behavior, target domains, and mapping quality point to a site move rather than ordinary maintenance.
02
Verify and monitor
Confirm the target domain, monitor source redirects at a lower cadence, and prioritize target URLs during first-crawl completion.
03
Clean up safely
Preview stable old redirected URLs, export mappings, and archive migration rows only after the redirect set looks safe to suppress.
Where teams use it
Domain migrations.
HTTPS or www canonical moves.
Platform relaunch redirect QA.
