"The downturn is finally getting to Google," says Jeffrey Lindsay, a senior analyst at Sanford C. Bernstein who has an outperform rating on Google's stock. The drop in revenue per click shows that Web users are clicking on ads to comparison-shop without buying products, and buying lower-cost items online compared with a year ago, Lindsay says. Those behaviors mean ads are less valuable to marketers, and result in lower payments to Google.

So advertisers are paying less per click to Google, Google in turn pays less per click to bloggers and other website owners, and customers are increasingly having the Adsense blindness where even the text ads blanded with content are not focused on.

If you're only monetization method is Adsense ads, you must be looking for other ways to earn money. Be it selling fixed fee banner ads, be it selling products via affiliate program, be it charging for content or be it by creating and selling your own product.

Adsense is not the way to go anymore...
