> Kohl’s gave out 1,000 $20 gift cards ($20k total), but the ad got 10,812 retweets. According to an estimate from the data analytics company SumAll, the value of a branded retweet is $20.37. So for a cost of $20k, Kohl’s got roughly $220k in value — about 10x its investment.
There's no way a retweet is worth $20-- or is this some weird power-law effect?
