Let's say I make an entirely different site (different domain, different provider) and get high rankings for it by braking all the rules. Then I place only one visible link saying "the site has moved. click here to go to the new location". Which takes the visitor to my real site.
It will work. I reported to Google a high-ranking site that was using CSS to hide whole lists of keywords and that site is still there (with its high rankings) after more than a month.
And here is the dilema:
If this doesn't harm the real site, then it is a good thing to do (I mean, you haven't got anything to lose, right?).
If it does harm the real site, then it might be a good thing to do to your competitor.
LOL. I just thought it's about time someone said Google has a pretty dumb robot. I'm tired of sites ranking above me by braking the rules. It doesn't even pick up sites <title>that repeat the same thing in the title. that repeat the same thing in the title. </title> quite the contary, this seems to give them a boost.
