Jeff Chang, a tech lead on the User Acquisition team at Pinterest shared their case:

1. They made all Pins look the same: Related Pins were made bigger, and the Main Pin (that a user found on Google and clicked) was made smaller.

Result: This trick increased signups by 100% but search traffic dropped by -10%.

2. Then they used the same large-size image file as before, but sized it down to fit inside the smaller Pin.

Result: This change increased the traffic difference from -10% to +10%, even though the design looks the same visually.

This means that you can change your price without reason, if it’s by less than 10%, without causing extreme reaction from your current customers.
