Imagine the worst scenario: no guestblog linking, no SERP at all, just direct Google military dictatorship with Big Google controlling every step of yours and obliging you to click on Adsense banners not less than 500 times a day. If you don't obey, they decide you are not democratic enough and send G-52s to pacify you
I'm just kidding -- I've seen Google turning into a major advertiser and kind of Internet policeman dictating web-masters, SEOs, content creators, and marketers the rules of their professional activity. Google has become a super corporation with an immense power, part of which USA government uses and tries to control. What if with all this technology advances in couple years they start controlling much greater sphere of public life and international relations than they do now? Corporations have become much stronger international players than some countries, and Google's number one of them. I can easily imagine Google condemning some country's government for being non-democratic and helping FBI and US military in their operations. How is Google different from a Special Service squad in this case? I'm sure every politician dreams of google's power at his command. Are there any reasons Google's owners should resist this?
After certain duration of time we heard a lot about Google Spam activities but can anyone tell me is there any proof for that or we just chaos for that !!!! Google will try to show relevant result by implementing lots of restrictions but after all that SEO guys finds a way out for promotional activities. On May 21st 2014 Google rolls out panda update i.e., 4.0 for content spamming !!!! Google always figure out in relevance results and he always implement harder rules for SEO guys to work more hard !!!!!
