Introduction
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).
Valid Characters for Keywords
Below is a chart of valid characters Amazon accepts for keywords.
Constraints on Keyword Characters
You can use blank spaces in a keyword, but leading or tailing spaces are not allowed.
You can not use quotation marks for your targets. Eg: garmin "245 music" charger - the "245 music" will not be valid.
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.
If your terms include the special "/" forward slash character, it's important to be aware that the Amazon system will ignore it. For instance, if you have keywords designed to capture sizes such as "1/4" or "1/8," the system may instead recognize "14" or "18."
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 the negative Exact match type, the negative keyword can have up to 10 parts.
Other valid characters include:
å or Å
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.
Valid Characters for Entity Name
Below is a chart of valid characters Amazon accepts for campaign names and ad group names.
Constraints on Entity Name Characters
You can use a blank space in an entity name, but leading or tailing spaces are not allowed.
The maximum length of a campaign name is 128 characters for sellers and 116 characters for vendors.
The maximum length of an ad group is 255 characters.
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.
