Absence of negative keywords can affect campaign performance tremendously while adding negative keywords helps curtail unwanted ad traffic, hence improving performance and better managing your budget.
Amazon ads offers a similar PPC platform structure, peripherally. Getting into the intricate details showcases the minute details that differentiates it from the rest.
So, while Google Ads and Bing Ads lets you add negative keywords in broad, exact and phrase match type, Amazon ads extends only the exact and phrase match type to its negative keywords.
Similarly when it comes to the limits of using negative keywords. In Bing Ads it is the following:
Each ad group or campaign can contain up to 20,000 negative keywords, and each negative keyword can contain a maximum of 100 characters.
|Campaign Negative Keywords||10000|
|Ad Group Negative Keywords||10000|
|Negative Keyword Exact Match||10 words or 80 characters|
|Negative Keyword Phrase Match||4 words or 80 characters|
Before beginning with adding negative keywords you might want to know about the available match types and what they mean.
So get started with negative keywords and make it a mandatory task. Rest, the performance will speak for itself.
