Hiding Text?

[newseed]

I know that Google will penalize sites using techniques to hide text but is visible for search engines.

 

I'd never heard of doing this before but a client requested this kind of technique where they would use text-indent: -9999px to move it off the screen. This seem old school and not advised to use.

 

Can anyone shed some light on this?

 

Thanks.

-9999px was what we used to make disjointed rollovers, off page then moved on when rolloed over.

 

I did see a blog that complained he was penalized for this by Google even though it is a old accessibility move as hiding them can make content unusable, I will see if I can find it.

I've found this on Google but it really doesn't go into specifics about text-indent and if it falls in the lines of hiding text regardless what's it meant for.
