A/B-split-testing in Silverstripe is easy enough (http://www.silverstripe.org/archive/show/63414) although not at all optimal, but how do I perform multi-variety experiments with Google Website Optimizer (GWO) in silverstripe when the CMS (tinyMCE) deletes half the script?

A typical GWO mulit-variety script looks like this:

<script>utmx_section("Section")</script>
Section-content (this will be changed by GWO on-the-fly.
</noscript>

The problem is the lonely, unbalanced "</noscript>" which is deleted by tinyMCE on save, which in return renders the script useless.

Anyone with a solution to this problem?

Could you not create a new page-type which has that code in, wrapped around the $Content? This is an alternative to putting it into TinyMCE and so you won't have those problems.

Also, you might want to disable the Content Negotiator (in _config.php):

ContentNegotiator::disable();

I'm afraid I haven't godt the possibility to edit (or indeed add) new templates so I need a solution that will work in the CMS...

You might need to allow <noscript> tags in TinyMCE, see http://doc.silverstripe.com/doku.php?id=htmleditorconfig
