Create separate Sanity or Contentful clients for published and draft content, then toggle between them with a preview flag. Add a webhook endpoint that validates a shared secret and calls revalidatePath so content publishes trigger on-demand ISR instead of full rebuilds.

Generate hreflang link tags from route params for every supported locale, plus an x-default entry pointing to the default locale. Combine this with next-intl middleware for locale routing so search engines can index each language variant correctly.

MDX compilation fails when content references a component not present in the registered component map. Register a fallback component that renders a warning in development and an empty element in production so a single missing component never breaks the build.

Run a CI script that flattens the default locale's JSON keys and compares them against every other locale file, exiting with an error when keys are missing. Also configure a fallback locale so untranslated keys never render as raw strings to users.

Slug changes between the old and new CMS break all existing inbound links. Build a permanent 301 redirect map from old URL patterns to new slugs, verify each redirect returns 301 rather than 302, and monitor Search Console for coverage errors after launch.

Content is scored across four 25-point dimensions: hook strength, engagement (readability, pacing, call to action), value (teaches, entertains, unique insight), and shareability (emotional triggers, quotable lines, platform fit). Totals above 80 are classified as viral, above 60 as strong.
