We're getting some feedback from different sellers that Amazon is about to change the product title length leading to listings being suppressed. In some cases it's already started...
Seems that the Health and Personal Care category will go down to 50 characters, while the Clothing section will be 80 characters in length.
A message to a seller from an Amazon support agent:
"the main reason for your listings to be suppressed is because of the number of characters in the title. Please make sure that the title is within 80 characters."
Who else has seen this happen recently? Please go and check your Inventory tab to see if you have anything listed in the "Suppressed" section.
