Therefore: 8,000,000,000 / (500,000,000 * 0.9 * 0.6) = $29.63 per person revenue per quarter. Could be as much as +- $10 given how arbitrary (research based, but still guesswork) my inputs were...
Somewhere around $100 per person per year seems insane but I guess how much do you spend per year on stuff?
P.S. please feel free to correct my figures!
Google can make >$100 a click for ads on mortgages or insurance keywords, but subscription models are locked in to revenue that doesn't scale with the category of use - unless they become some sort of affiliate service.
If the seller has $1000 per click, that's really going to distort the market...
Presumably the value of advertising is highly correlated to the amount of money you spend (on things you have some choice over).
Disposable income is a strongly skewed distribution (across countries, within most countries).
An average won't help you much if you want too know how much Google makes off you!
Guess how many times an average person clicks on an ad knowingly/unknowingly.
