What it means
A refresh is more than changing the date. It means replacing outdated information, filling in missing subtopics, and confirming the page still fits the intent behind its queries.
Because the page keeps the visibility and links it has already earned, a refresh often takes less effort than writing a new piece from scratch.
How to use it
When you pick refresh candidates, prioritize pages that are losing visibility, sit close to your business goals, and still target a valid intent. Record baseline data and a measurement window for every refresh.
