<b>Data refresh or algorithm change? A subtle but useful split</b>
This week on the radar: sources that separate a re-scoring from a new system.

Confirmed:
— <a href="https://developers.google.com/search/blog">Search Central</a> — a refresh re-runs an existing system on fresh data; an update changes the system's logic. Same system can do both at different times.
— <a href="https://status.search.google.com/">Search Status Dashboard</a> — naming conventions sometimes signal which is which.

Chatter:
— <a href="https://www.seroundtable.com/">Roundtable</a> — readers note refreshes often produce cleaner recoveries because the logic didn't move under you.

Read this:
— <a href="https://searchengineland.com/">Search Engine Land</a> — glossary entry distinguishing the two.

One to bookmark: Search Central's update glossary — it makes the vocabulary precise.
