Are you using the Recommendations section in the ad console to find new keyword opportunities?

These recommendations are based on Amazon’s first-party data, so they often surface relevant, emerging keywords - similar to what you'd find in your Auto or Category campaign search term reports.

If you’re working with an Amazon ad rep, you can ask them to tailor the suggestions based on your campaign structure and goals.

The search volume of keywords and Amazon's search autocomplete change constantly.

This is another resource you can use to capitalize on new opportunities as they emerge.
