If you are reading this blog, then there is a good chance that you either provide SEO services for a living, actively work on SEO for your own web properties, or are otherwise interested in search engine optimization. And easily the biggest search engine we all target is Google.... but Google itself could be looking to slowly but surely devalue organic results.

Aaron Wall recently published a post on his SEO Book blog about this very topic. In effect, he says that all the shopping ads above the fold of a typical Google search results page are actually hurting the consumer by limiting their choices. To the average web user, these ads may look useful, because they're seemingly good for comparison shopping and getting pointed in the right direction. However, these results aren't exactly what they appear to be.

That's because, as you know, Google makes money with all of those ads and every time you click on one, that's money in the bank for the guys and gals in Mountain View, California. All the other links above the fold are to other Google pages that are similarly wrapped in more Google money-making monitor space. They want you to click on any of these and not on any of the organic results below the fold.

A great example of this is Google Flight Search. Consumers think Google is finding them the best possible deal on their next flight to Vegas, but according to Charlie Leocha of the Consumer Travel Alliance, "It is only going to a small select group of airlines and including them in Flight Search... Google and the airlines have a sweetheart deal with each other."

A scarier one? A recent ad that appeared on the Google SERP for the term "SEO" read: "Forget about SEO. To be visible in Google today, try AdWords."

How's that for a slap in the face?
