You may be wondering "can I use special characters or accented characters in my keyword targets or campaign names?" and "are the rules the same in your app as it is in Amazon?"

Our rules regarding special characters are the same as Amazon's.

Let's go through these rules by keywords and entity names (campaign & ad group).


Keywords

Valid Keyword Characters

Below is a chart of valid characters Amazon accepts for keywords.

Constraints on Keyword Characters

  • You can use a blank space in a keyword, but leading or tailing space are not allowed.

  • When using the period '.' character, it can only be used in the middle of keywords or in the middle of blank spaces.

  • When using the hyphen '-' or the plus '+' characters, they can only be used in the middle of keywords and cannot have blank spaces around them. This applies only to keywords; campaign names do not have this restriction.

  • The maximum length of characters in a keyword is 80.

  • The maximum number of parts for a positive keyword is 10.

  • The maximum number of parts for a negative keyword is 4.

  • For negative Exact match type, the negative keyword can have up to 10 parts.

  • Other valid characters are included in the following Unicode scope: {\u3000 to \u309F}, {\u30A0 to \u30FF}, {\u4E00 to \u9FFF}, and {\uFF00 to \uFFEF}. This means that hiragana, katakana, and kanji characters are also allowed in keywords.
