Why am I charting in some categories (like my sub-category) but not my main category?

We fetch charts from every category and country that we can.

If you see your podcast charting in a sub-category but not in your "main" category — for example, if your main genre is Business, but you're only charting in Entrepreneurship — that's because you've made it onto the charts in the subcategory but not in the main category. Charts for larger categories tend to be more competitive than for subcategories.
