Single source of revenue?
They can virtually overnight turn into the number one most profitable, largest corporation on the face of this planet (if they so wish). And no i am not talking about AdSense, AdWords or even double click.
Read my lips, "affiliate programs". Thousands if not millions of different affiliate programs.
And if they choose to go down that path...forget the rest.
"You searched for hotels in Paris...would you like to see related products and services". [which each pay us up to 25% per booking]
"You searched for Stock Market software...would you like to see related products and services". [which each pay us 15%-75% per sale]
"You searched for lawyer in hollywood...would you like to see related products and services". [which each pay us $20-$50 per lead] :)
The list goes on and on...a humongous list.
Adwords/adsense are just the tip of the iceberg...a little data collecting execersize. Nothing more nothing less....wait for the real thing to show. It will knock everyone's socks off.
But enough giving them ideas already, i dislike this octopus enough as is.
