Direct Answer
Usually not long. The median citation lifespan is 0 days, the mean is 6.8 days, and 73.5% of citations appear once and then vanish.
What this means
Operators must adjust measurement frameworks to account for rapid decay, ensuring publishing and refresh cycles align with actual citation lifespans rather than traditional search timelines.
