Amazon titles can use periods. Amazon titles can use punctuation marks, but try not to include unnecessary punctuation marks in the title. At the same time, the first letter of the word should be capitalized, but do not use all capital letters, which is not conducive to reading.

In the title and the entire listing copy, you cannot use the Chinese input method to write commas, periods (、。), etc. These symbols do not exist in English. The English comma is the comma (,) under the English input method, and the period is a dot (.). There are also brackets. The spacing between English brackets and colons is narrower than that of Chinese brackets. In a word, punctuation marks must be written in the English input method to be standard, but you must also be careful not to use punctuation marks that do not exist in English.
