Google Revamps SERPs, for Money? – Why Would Google Change Free SERPs?

I guess it was bound to happen. Google has started to experiment with manipulating the organic results listings in order to find ways to earn additional revenue, as well as expand their service offerings to their users. Google has added things in the free results listings in the past, but this newest change has monumental impact on webmasters, and search engine marketers, as well as search engine optimization overall. The trouble that the bean counters may not see is that Google’s new reshaping of the free results pages could also spell financial disaster. Google has begun adding another referral, much like the one that comes up if you misspell a word, but this new offering replaces the results one would normally see in position numbers 6, 7, and 8.
……
You did read it correctly; Google replaces the free results listing in positions 6, 7, and 8 with referrals for related results of both commercial and non-commercial interests.
……
The most glaring example of the commercial aspect is found when doing a search for “on demand” as the keyword term. Using that search term, we now see results in positions 6, 7, and 8 replaced by three (3) different results listings for Comcast Cable Corp.
Not sure if this is effecting what you are speaking of, but interesting nonetheless.
