I've noticed lately that Amazon's search also returns products if the query matches customer Q&A questions.
So if you are wanting to purchase, say, a 10ga extension cord, and UL listing is important to you, searching for '10 Gauge Extension Cord UL' will return many non-UL listed cords with customers asking 'Is this UL Listed?'. It makes for a very frustrating shopping experience.
It's like they want marketers to post fake reviews. We've all seen the so-called users who write "I was very disappointed in the Ronco Widget Tensioner. I returned it and bought a Spacely Sprockets(tm) Grommet Guard instead. That worked perfectly!"
