Median reviews · Top 10
The typical review count of the products in the top 10. A rough measure of how established the market is.
The median number of ratings of the products in positions 1 to 10 for your active keywords, the same way as Median price and Deals: per keyword and capture, then across them. Many reviews at the top usually mean a mature market that is harder to break into. Few reviews suggest room for new products.
