If you’re having trouble lifting your adsense income, you might want to try a little technique that’s been bubbling just under radar for a few years now, called Adsense arbitrage. Quite a few people know about this already, but I’m often surprised by the number of people who don’t. It can really help lift your earnings quickly, if done well.
Arbitrage means “profiting from differences in the price of a single security that is traded on more than one market”. In search terms, that means buying a cheap click on, say, Yahoo! , sending the visitor to a page with higher value Adsense listings, and, if the visitor clicks, you pocket the difference. You can, of course, get traffic from anywhere, but obviously the more targeted the traffic, the better.
There’s an excellent three-part tutorial on this topic by GrayWolf. As the writer notes, this approach isn’t for the faint hearted, but it can pay dividends if you’re prepared to work it.
