For Sponsored Brand Video campaigns, the ideal keyword count is usually around 25–50 high-quality, tightly relevant keywords per ad group.
Here’s why:
Too few keywords (under 15) might limit reach and visibility.
Too many keywords (100+) can dilute performance and make it harder to optimize.
Focusing on high-intent, product-specific keywords helps Amazon’s algorithm serve your video in more relevant placements, improving click-through and conversion rates.
