This is just one example of the result of a scarcity campaign. You can see that the campaign affects conversion rates most directly, leading to a huge increase in sales, while traffic levels stayed about the same.
These graphs show the revenue generated per visitor to a site, during the scarcity campaign. With this data, nothing is skewed by traffic and the data can’t be “cheated” by showing a revenue increase that’s really just the result of a traffic windfall.
