Who earn more advertising money. Facebook, Yahoo or Google?

[Jason]

Pls elaborate.
@Ugo : Thank you for your sharing. How about Yahoo and Facebook? I do wonder why there are still people like myself who fancy Google despite it looks SO PLAIN compared Yahoo which is too cluttered. I love Google because it helps me to find answers to my problems 95% of the time. But the plain jane Google still amazed me why many people still love using it. (apart from people like me).

Google Ads for sure because its ads are very much audience specific people are more & more choosing google adwords.

Google

They earn in this order Google, Yahoo and Facebook - the search ads for Google and Yahoo make them earn more than Facebook

[Johnny]

The correct order should be Google > Facebook > Yahoo. The major revenue for all three giants comes from Ads. And if you would GOOGLE for their respective revenue ...

@OP "Google despite it looks SO PLAIN compared Yahoo w"
Having a clean, and uncluttered look is a good thing. Google's sole purpose is to find things you're looking for. Anything but a search bar and a content block for results is superfluous (hyperbole)

Yes! The correct order is Google >> Facebook >> Yahoo or Bing. But Facebook gather it's audience constantly and can beat Google in future. There are more chances that Facebook get first position in this table in future. Because most of the advertisers believe to use Facebook ads for targeting young audience.
