A recent Tweet from SEMrush highlights Google’s new SERP test for sub-category tags in the search results. The tweet which included a screenshot showed sub-categories for product-related searches.
However, the specific use of the new “side bar filter design” is unclear. But it appears that Google is trying to make navigating easier for features like “Reviews”, as per SEMrush.
