The point being? Or, to better phrase, "What is Google doing?"
Google is cleverly using Social Engineering for the purposes of throwing out smoke and mirrors. What is their objective? It's threefold:
(a). Their main objective is to increase the number of AdWords Advertisers, thereby instantly increasing their revenues. Clearly, these latest algo modifications have forced many IMers to sink money into AdWords to make up for their drop in the SERPs.
(b). Google is attempting to create subterfuge to ward off the Antitrust suits they are facing. If you are following that development, then you know that the FTC just hired Beth Wilkinson. Beth is a former DOJ prosecutor, who has never lost a case. When the FTC made that move, it was letting Google know that they are in fact going to be sued by the FTC much like the case of
The United States vs. Microsoft. Google is also facing the same type of lawsuit in Europe. If you recall, when Microsoft lost that lawsuit, it opened up the doors for companies like Google to sprout up.
(c). These algo modifications are also part of a public social engineering PR campaign to discourage and confuse those who compete against Google. Who competes against Google? Anyone not paying Google for advertising!
In summation, this is a time and era SEO wise, when everyone must buckle up, remain calm and ride out the storm. Right now, there are not a lot of concrete absolutes but one thing is for sure; you should not altogether stop your backlink building campaigns.
