I’m trying to run a test which has a variable, similar to your “Buy this for $45/Buy now for $45″ test above.

I have this section on about 100 tag pages:
<div class="srch_content2"><h1>Reports Tagged: wrestling</h1></div>​

The only thing that varies is the “wrestling” word. I’d like to test a variation with different copy, such as:
<div class="srch_content2"><h1>Reports Tagged: wrestling - scroll down to learn more.</h1></div>​​
… where “wrestling” is replaced by whichever word is on the respective tag page.

I’ve tried to use your example above, but with no luck. Any pointers?
