Review Routes Before an Outsourced Website Design Change
A route review protects useful links, page meaning, redirects, and analytics when website design changes.

A visual redesign can have a quiet effect on URLs. Review routes before layouts change so an outsourced website designer knows which addresses are stable and which require a documented decision.
List the routes in scope
Record current URL, page purpose, owner, status, and destination after the change. Mark routes that appear in navigation, search results, campaigns, or useful external links.
Decide each change explicitly
Keep, change, combine, redirect, or retire each route. Record the reason and the person who approves it. Do not let a missing page in a mockup make the decision by accident.
Check links and measurements
Review internal links, canonical information, analytics references, and any external communication that depends on the address. Technical owners should confirm implementation details.
Test the final route
Open the published path, follow key links, and record the result. Keep unresolved redirects with an owner until they are checked.

Frequently asked questions
Should route review happen before design?
Yes. It gives the designer a stable page list and exposes dependencies before a visual decision is treated as final.
Who approves a route change?
Name the owner of the page or site structure. Implementation teams can advise, but should not infer the business decision.
