Summarizing keyword categories is a crucial step in **SEO data analysis**, as it enables you to quickly identify which content areas are performing well and which may represent opportunities for growth. By aggregating **search volumes** by `category`, you can spot gaps in your content strategy and make informed decisions about where to focus your efforts.
