Direct answer

A refresh should resolve a current reader need, correct evidence, improve structure or consolidate ownership; a date change alone is not a refresh.

Practical steps

  1. Select pages by task and evidence.
  2. Document the old state.
  3. Make focused material changes.
  4. Review sources and links.
  5. Measure comparable outcomes.

Common mistakes

  • Fake freshness.
  • Adding filler.
  • Changing multiple intent owners without mapping.

Limitations

  • Seasonality confounds before/after comparisons.
  • Some declines reflect changed demand.
