Duplicate content concern from scrolling customer reviews?

[giggle]

Hi

We have just added a common scrolling text box that shows (positive!) customer reviews. If a visitor drills down to a particular product then only reviews of that product are shown. If there are no reviews the whole list (capped) is displayed.

I was just thinking that this might cause us to trip the duplicate content trap.

Investigating I found an article that suggests putting something like we have into an iFrame.

Two questions: 1. Is this necessary 2. Will Google still crawl what's in an iFrame?

Thanks

Keeping the changing content in an iframe will definitely help Google to know what is relevant for your page. The content that is in an iframe is actually on a separate URL, so Google may crawl it, but it doesn't "count" for the parent URL.

And an iframe may trigger red flags with browsers or some security tools, best to minimize the reviews content perhaps displaying only the ones from relevant products if the one viewed has none.
