Competitor research from their own pages
You are sizing up a market. These filters come from what each product claims about itself: how it positions itself, what it charges, who it names as an alternative, what proof it publishes.
23166 products read in full so far. A claim is only recorded when the page said it in its own words, with the sentence quoted. This is a growing slice of the catalog, not a replacement for it.
