Website migration checklist
Work from the earliest technical signal towards search visibility. Move to the next layer only when the one before it matches the migration plan.
Signal ladder
Find the first layer that doesn’t match the plan
Your selections are saved only in this browser. Stop at the first layer that contains an unexplained failure, then fix or explain it before relying on a later metric as the diagnosis.
Before launch
Do you have a reliable version of the old site to compare with the new one?
Redirects and responses
Can users and crawlers reach the right new page?
Crawling
Are search engines discovering and revisiting the new URLs?
Indexing and visibility
Are the new pages replacing the old ones and appearing as intended?
Diagnostic record
Trace one problem backwards
Record the outcome you noticed, the earliest signal that failed and what you will test next. These notes are stored in this browser with the checklist.
