If you have a splash screen - with some text on it visible at all resolutions - but with some text off screen at the bottom, only visible at higher screen resolutions (like very high) - and a no scroll set - is this actually against the rules?
its not spam - but the new changes soon to be in force make me itchy that it might automatically be seen as such, and penalised...
I recently removed some links hidden in this way (even though the links were only to internal pages on the site) because I felt it was fairly obvious if I were to be reviewed manually. I suspect that Google manual reviewers probably have seen examples of more types of deceit and trickery than I could think of in a year.
Of course I may now do a site map that emphasises the pages I want to promote - but that will be visible and so cause no problem.
Of course, it's very unlikely that I will be subject to a manual review so maybe I shouldn't worry.
