Which keywords may offer a larger amount of impressions with higher search volume?

Category keywords are generally broader and encompass a wider range of products or services within a specific category, leading to higher search volume and, consequently, more impressions. For example, "running shoes" is a category keyword that would generate significantly more impressions than a specific brand keyword like "Nike running shoes." While brand keywords can be highly relevant and convert well, their search volume is limited to queries specifically mentioning that brand.
