hmm, yeah I had a look through that post, but I think there's a couple of issues:
1) would it actually work with google searches?
So it seems like if I googled for: 'this is my test' it'd work for the page that contains:
'
This is my test. And some other text.'
However google more commonly finds things like:
'
This although untested,
is to be
my final
test.
when you search for 'this is my test'. So I don't 'think' this'd work - correct me if I'm wrong though!
What I have found is sites that show how to easily hide parts of your page from google, eg:
http://oy-oy.eu/page/jscode/
which seems to involve just printing it to the same place as a document.write script (perhaps even putting <script> tags or something around the hidden content would work).
But this'd mean google would simply be indexing the exact text that'll be visible? Or am I talking rubbish?!
