If someone were to stuff a bunch of keywords into a div and then use the display:none; style to the div, how would SEs treat that? Would they consider that has part of the site or would they consider it just fluff and not take it into consideration at all? Thoughts?
um, I can't speak for the others, but google won't consider it fluff, they will ban you (been there, took a long while, but eventually they got me).
This is called hidden text, could also be classed as cloackin i suppose (showing visiters one thing and search engines another) it is also called spam and will get you banned (eventually) from search engines.
Umm! What I have seen regarding use of CSS is: G can detect text hidden by CSS and will panalize. The things which we can do are like using <H1>, <H2>, <H3>, <B>, <A> tags and displaying them simple text with CSS. It will work. I don't rem who has given example of http://www.globtier.com in the forum. If you see the source code of home page you will see <div id="essay1" style="LEFT:0px;TOP:0px; VISIBILITY:hidden; POSITION:absolute;"> This site is NOT banned but panalized.
Hmm ok, some good insight, thanks. I don't practice it nor will I ever, just wanted to know some opinions on it.
