Lost 30% traffic overnight after Google silently deindexed many product pages without any warning or manual action. I built a simple daily checker to monitor index status for URLs and quickly detect drops. It even helped identify competitor ranking issues.
That's brutal. Google's silence on index drops is maddening. Your tool sounds like a solid early warning system—do you just alert on deindexing, or do you also track ranking recovery trends after re-indexing?
