That Little "Google Search Update" Banner in Your Search Console? Here's What It Actually Means — And What to Do Next

Just a date and a vague warning that something happened. Here's the thing: that annotation is not a penalty notice, and it didn't arrive in a vacuum. It landed in the middle of a core update rollout, an eleven-month impression reporting bug, and one of the most data-chaotic stretches Google Search has had in years. This post explains exactly what it means and what to do with it.
