<b>The campaign that worked too briefly</b>

It was the morning after a mid-size apparel brand's big collab launch, and mentions were up 400%. Everyone called it a hit and moved on. The numbers were intoxicating, the room was happy.

But one analyst didn't track the peak — she tracked the decay. She plotted how fast the spike fell back to baseline and compared it to past campaigns. This one collapsed in 3 days; their best-ever launch had held elevated for 11. Loud, but brittle. The conversation had no second act.

Digging in, she found the collab drove curiosity but no community — people posted once and never returned to the topic. The next campaign was built for follow-through, with reasons to keep talking. Its mentions decayed over 9 days instead of 3, and tripled the downstream traffic of the louder launch.

The takeaway: a campaign's peak flatters you; its decay curve tells the truth. A 400% spike that dies in 3 days loses to a smaller one that lingers. Measure how long people keep talking, not how loudly they start.
