1

Build the toolkit around risk

Start with what would hurt most if it broke: checkout, sign-up, key landing pages, legal content, localized markets. Choose tools that cover those risks first, then broaden.

2

Automate the repeatable, review the rest

Crawlers, audits and visual monitoring can run on a schedule. Human review remains essential for content accuracy, brand intent and translation quality — the right tools focus that review on what changed.
