A Study of Viral Pins (Part 3)

Welcome to the third part of our research of viral pins on Pinterest! Today we are looking at the growth trajectory of viral pins. We've been watching a bunch of pins as they grew virally from zero to thousands of repins per pin. While we noticed quite a bit of fluctuation, it is safe to say that all of them were acquiring repins extremely fast during the first day, and then the rate of acquiring new repins was slowing down every day after the first day. The chart below shows how these viral pins grew over a 30 day period. The horizontal axis represent the age of the pin in days. The vertical axis represents the percentage of pins acquired by this age.

And here is the average growth curve:

As you can see, on average 90% of viral growth happens during the first 4 days of pin's life, and roughly half of all repins are acquired during the first day. So, if you see that one of your pins got repinned 1,000 times during the first 24 hours, chances are it will ultimately accumulate around 2,000 repins.

That's all for today! Feel free to check out Part 1 and Part 2 of our research.
