How much does Google Ads pay per click or page view?

Primarily from ads, usually AdSense though other ad networks exist such as Yahoo Ads, Bidvertiser, AdBrite, ValueClick and others. Revenues are generated both for each impression (or display), but higher revenues are due to clicks, usually denoted CPM or clicks per thousand (where M is the Roman numeral 1,000).

Next is affiliate traffic, which is usually a CPA arrangement or cost per acquisition: every customer who clicks an ad on your site, and signs up for a service or buys a product entitles you to a revenue. Other affiliates arrange on a recurring percentage of sale, usually applied to monthly subscriptions (such as web hosting) or continuous pay (such as online poker).

A little less common is getting paid to do a review, though this works if you have a good online reputation or presence, or if you happen to be part of a blogging network.
