Multi currency, duplicate content and drop down box

Multi currency would cause duplicate content?

[funfun168]

Hello

I am running a multi currency cart in which US dollar, Euro and GBP was used while US dollar is the default currency

when the product showing up in US dollar, the url is like this: http://www.mywebsite/widget.html
When I choose GBP in the dropdown box, the URL show up as:http://www.mywebsite/widget.html?currency=GBP
When I choose EURO in the dropdown box, the URL show up as:http://www.mywebsite/widget.html?currency=EURO

It seems that this 3 URL showing almost the same, here is what I am in doubt:
1) there is just difference in the currency for the 3 URLs. Would it be regarded as duplicate content?
2) would the search engine only crawl the page in default currency?as my currency box is a dropdown menu.

Thank you

Spiders don't crawl forms actions, unless those duplicated pages are hyperlinked from other pages, you should be fine.

1) there is just difference in the currency for the 3 URLs. Would it be regarded as duplicate content?

Yes, it would. You should be careful to not submit variations of a page to Google Sitemaps, and you may want to mark these variations with a "noindex" meta tag.

2) would the search engine only crawl the page in default currency?as my currency box is a dropdown menu.

The dropdown is used one time, to select a currency, correct? Once a user switches to Euros (for example), are there any links on the page with a "currency=EUROS" parameter? If so, search engines will follow and index these links.
