I was surprised to see my 5 months old website moving up on 1st page. Haven't updated it for a month, nor I have built any links for that period.
no way, not in web design.
Web developer's job is to get the visitor the information to respond quickly and with a few clicks as possible. The longer they linger without finding what they came for, the more likely it will be for the visitor to hit the BACK button and be gone before they click exactly what we want them to (CPA offer, Contact form, email signup). We work too hard to attract that traffic. Close the deal.
Well first, fortunately, 95% of SEOs are so bleachy white or not creative enough, and wouldn't even think of this. Secondly, is there even a way to tell that you've been -1'd (my new verb)? Not too mention where the hell it's coming from.
This is likely a flawed assumption.
Google has already demonstrated that they will not allow Google Bombing and AdSense Manipulation, two variations of this assumption you are making about a third product of theirs.
