I think you underestimate the value of all the product reviews on Amazon. While I doubt that I've been influenced by ads on Google, I'm influenced all the time by the reviews on Amazon. Yeah, Amazon needs to do better about the fake reviews (and they are working on it, it's gotten better).

But there is a huge amount of value tied up in those reviews. I'd argue that it creates such a network effect that starting up a competitor would be really hard. Possible but Amazon would have to stumble.

What about reviews in Turkish language and what about shipping to Turkey? Amazon is mostly for English speaking world.

On the other hand Google, Apple, Microsoft has no language barrier. Amazon is 4th among them.
