Proposed with the evidence. A person confirms it.

Why it matters

Google keeps the source of a redirect as an alternate name and may still show old URLs to people who search for the old domain or brand; its redirect guide calls this normal and says it fades over time. Removing redirects early breaks those visits and the consolidation of signals. Google's site move guide says to keep redirects generally at least one year so it can transfer all signals, and that small to medium sites take a few weeks for most pages to move. Said at Search Central Live: a site move takes one to three months on average and up to about a year, because Google's slowest signal is recalculated only about once a year (a partly uncertain passage of the recording). Asked how to plan a migration that does not leave many URLs unindexed, a Google panelist said sitemaps are not the main tool: decide first what matters from the business's perspective, for example whether to consolidate languages; listing the new URLs in a sitemap cannot hurt.

How to meet it

Map every old URL to its final new URL in one hop (DEV-CAN-10), keep the redirects for at least a year and ideally indefinitely, use Search Console's Change of address tool for domain moves, submit the new sitemaps, update internal links to the new URLs so pages do not rely on redirects alone, and follow the new property's indexing and traffic against a pre-migration baseline.

How to test it

Old URLs still answer 301 to the right targets months after launch; in Search Console the new property's indexed pages rise as the old property's fall.

How Regensbot covers it

AssistedNeedsYour verified site

Regensbot proposes a verdict with the evidence; a person on your team confirms it.

The evidence comes from your verified site: its pages, its profile and the files you upload.

You verify the site by a DNS TXT record, a meta tag or a file. Regensbot then keeps a checklist item for this requirement, with a state, a guide, an evidence upload and reminders.

Audit

Check it on your site.

One audit checks a URL against all 138 requirements and returns one finding for each, with its source. One URL decides 66; for each of the others, the finding says which source to connect.
