In my niche we have a distributor who feeds his customers with his database.
Almost all of my competitors who uses this database for their webshop are gone out of serps. Instead of the customers now the distributor shows up for widget searchs.
We do not use the database for our webshop but writing own descriptions. We got a cut of 50% but were not vanished.
We find heavy loads of price comparing sites in top ten and plenty site from Swiss although we are located in germany.
Strange is, that sometimes for a widget search comes up plenty of shops and search for an other widget comes up information pages mixed up with brands.
Maybe google set up a database where they store information for widget searches, like:
-> widget a - most poeple looking for stores -> show more stores
-> widget b -> most poeple love to find more information -> show information site and brands
