Freeze the source of truth
Choose one protected master backup and stop combining files from multiple build folders.
Create a clean output directory
Build production files in a new empty directory rather than overwriting an unknown deployment folder.
Use an exact manifest
Copy only approved files and reject missing or unexpected critical files.
Validate before upload
Check root structure, internal links, XML, canonical URLs, required control files, and ZIP integrity.
Verify after deployment
Open the production domain, critical pages, robots.txt, sitemap.xml, and ads.txt, then preserve rollback access.
