There's limited space on the frontpage of Amazon.com, too. If I go to Amazon looking for chips, I won't see it on the front page so I'm going to end up going to the Chips section of the site. If you're just at the store for a bag of chips, you go the chips aisle, which is also meticulously planned to specifically influence which brand of chips you will buy. I fail to see how this is any different than going to the Chips section of Amazon and seeing a specially arranged selection of chips.
>2. Brick-and-mortar stores usually only sell a few forms of same product. If I want olive oil, there's some store brand, some italian-looking brand, and maybe a brand that advertises some sort of magical health benefits. There might be a few variations for the level of refinement/virginity. It's easy for me to look at all the options and compare them. When I look at a search page on Amazon, there's often 100's of hits, and it's often pretty unclear if there's any difference between them that I'd care about (see https://www.amazon.com/s?k=olive+oil).
I don't really see what this has to do with the topic at hand. Can you clarify your point?
So in reality, if your product is on page 5, it is perhaps as good as not being on Amazon anyway for that particular query.
If you look at it this way, the space constraint isn't much different than brick and mortar.
Then you throw in Amazon Shopping ads (aka Sponsored Products) and the shelf space metaphor gets muddled further, because it's like as if every store visitor saw unique and different endcap displays and shelving ordering. There is less individual tailoring to search results than you might expect on Amazon (especially compared to information search engines like GoogleBingBingGo) but it is still a factor.
Then there is the factor of endemic counterfeiting in some categories, so the sketchier the listings are the more likely you are to just buy a counterfeit product, which would never happen in a typical brick and mortar retail shop.
IMO Amazon's private labels are so minor and make up such a small portion of store sales that it ranks very low on the scale of things that Amazon does that are morally/legally questionable.
1. There's limited space at the front of a brick and mortar store. It's not practical to put most of the items at the front, so anyone who's not just there for a bag of chips ends up looking through the aisles anyways.
