Schmidt was speaking in Berlin, Germany, trying to explain why it shouldn't be regulated as if it were a gatekeeper of the internet, since other companies like Amazon and Facebook are just as influential.
Google was recently hit with an $4 (its search engine market share is around 90%).
Since many people are likely to go directly to Amazon.com if they're shopping, Schmidt says, it has become a bigger search competitor than Bing or Yahoo.
"Many people think our main competition is Bing or Yahoo$4. But, really, our biggest search competitor is Amazon," Schmidt says.
Although Schmidt makes the point to show it's not the only "gatekeeper of the internet," Google has meanwhile been $4 (PLAs), which help make it more attractive for shopping. The more Amazon-like features that Google offers through PLAs - like product descriptions and reviews - the less likely people will be to intuitively start on Amazon, unless they're already loyal Amazon users.
Schmidt also called out Yelp and TripAdvisor, which have complained that Google's de facto monopoly $4. Schmidt said their businesses have actually been thriving, $4.
"The reality is that Google works very differently from other companies that have been called gatekeepers and regulated as such," he says. "?No one is stuck using Google."
