Redirect Review for an Outsourced Website Project
A practical research guide to mapping, testing, and documenting redirects during outsourced website changes.

Redirect work is a content and infrastructure handoff. The safest review starts with a complete old-URL inventory, maps each retained or changed page, and tests the result before the company owner approves release.
Mapping table
| Old URL state | Decision | Evidence |
| --- | --- | --- |
| Same purpose | Keep URL | Page review |
| Renamed purpose | Map to closest useful page | Redirect test |
| Removed content | Confirm destination or removal | Owner decision |
| Unknown | Investigate before release | Crawl and log |
Methodology
This synthesis uses Google’s site-move guidance, RFC 9110, the sitemap protocol, Search Central’s SEO guidance, W3C, OWASP, NIST, and Git references. The numeric statements describe standards only. Recommendations are for a company that retains final control while an external team implements the change.

URL inventory
Export the current route list from the repository, sitemap, analytics, and link sources available to the company. Mark each route as kept, redirected, consolidated, or investigated. Do not treat a missing sitemap entry as proof that a URL has no value.
Redirect behavior
Google recommends permanent server-side redirects for lasting moves and a direct mapping to the new destination. Test the response, final URL, content purpose, canonical, and internal links. A chain can hide an incorrect mapping even when the browser eventually reaches a page.
Release evidence
Save the old URL, expected destination, observed status, date, tester, and exception. The delivery team can prepare the map and tests. A company owner should approve the risk of removing, merging, or redirecting pages.
Consolidated statistics
The article uses 3xx as the HTTP redirect class, 4 WCAG principles, and 3 Core Web Vitals metrics. These counts are not estimates of redirect success or search traffic.

Frequently asked questions
Should every old URL redirect to the home page?
No. Map a changed URL to the closest useful destination. A generic home-page redirect can discard the old page’s purpose and confuse visitors.
Who approves URL removal?
The company owner should approve removal after reviewing search, analytics, links, and business purpose. The external team should record the evidence.
