I think it's a business strategy...they can increase and decrease something. Google and Yahoo are strong enough to change their policy.
sorry for my late reply. here is a link to the news. http://searchengineland.com/yahoo-to-drop-paid-inclusion-program-27852 other agencies have made it official. its not that yahoo is throwing away money, its part of the yahoo-bing deal. next year will look different for SEM and SEO thats for sure.
Wow.. well its about time really.. Yahoo charging for a directory listing? It's almost equivalent to a PAID link. It's about time.
Yahoo is not going to throw away all of that money. For all we know, Yahoo may be plotting to overthrow Google!
lol... I thought you were serious at first. I'm not saying its impossible to "overthrow" google... but...pretty damn near.
