A dated event that has passed and is still open for indexing sends people to something that already happened. Search engines demote it; readers who arrive are worse off than if they had found nothing.
The finding reads:
critical stale-event the date … passed more than … days ago and the page is still open to indexing — the engine is showing people something that no longer exists. Close it with noindex, redirect to the current one, or rewrite it as a report on what happenedThe event is over and the page is still open to indexing. Close it with noindex, redirect to the current one, or rewrite it as a report on what happened.
Reported per page even when it is common. Appearing on many pages is the nature of this finding rather than evidence of one template defect, so collapsing it would hide real work.
