Redirect Chain Reviews for Outsourced Website Projects
How to review redirect maps and chains as part of a controlled outsourced website migration.
A redirect map is more than a list of old and new URLs. It is a claim about how visitors, crawlers, bookmarks, and shared links should reach the new information architecture.
Research basis
HTTP semantics distinguish temporary and permanent redirection, while Google Search documentation discusses canonical signals and redirect handling. An outsourced review should test the final destination, avoid unnecessary hops, and preserve the user's intended content wherever the migration allows.
Evidence to collect
For each source URL, record status, destination, redirect type, hop count, destination status, and rationale. Include removed pages and protocol or hostname variants, then retest a sample after rules are deployed to the test environment.

Frequently asked questions
Is every old URL entitled to a redirect?
No. Map routes where the new destination preserves the user's likely intent, and document deliberate removals or replacements.
Are multiple redirects always wrong?
They are a useful signal to investigate. A direct final destination is generally easier to test and less fragile than a chain.
