I need a fast easy way to cloak...

How can I hide some of the text on my pages?

[lizzie]

I have some good rankings now but some of the
text, in fact all of it on some pages, must be completely changed. This will ruin my great rankings. How can I do this? Right now I have an external javascript redirect to another page but I would rather somehow hide all the text and insert new text in a way that will let the search engines think it is still the same text they loved.

You've lost me on this lizzie, why must you change the text?

[rcjordan]

If you must change, you could keep the old content on the page (in my preference order):
- css positioning
- noframes
- noscript

If your encapsulating old content, I think noframes enjoys the least risk of being labeled as spam. Make it truly noframes content. You can rank well with noframes in Google and AV.

With noframes I would be changing the carefully crafted
page structure by adding the noframes tags as well as new
text to the page outside the noframes tags.

Where can I learn how to do the other two options?
