Duplicate pages in language versions, noindex in sitemap and canonical URLs in sitemap?

[TradingFloor.com]

Hi SEO experts!

We are currently in the midst of reducing our amount of duplicate titles in order to optimize our SEO efforts. A lot of the "duplicate titles" come from having several language versions of our site.

Therefore, I am wondering:

1. If we start using "" to make Google (and others) aware of alternative language versions of a given site/URL, how big a problem will "duplicate titles" then be across our domains/site versions?

2. Is it a problem that we in our sitemap include (many) URL's to pages that are marked with noindex?

3. Are there any problems with having a sitemap that includes pages that includes canonical URL's to other pages?

Thanks in advance!

If you have translations, that is content that is exactly the same, just translated, HREFLANG is highly recommended for Google. Bing uses another tag though. However, your titles should be different give that they are in different languages.

I wouldn't put pages in the sitemap that have a noindex. It won't hurt you by any means, just seems a waste of time.

**3. Are there any problems with having a sitemap that includes pages that includes canonical URL's to other pages? **

It's not recommended but it's also not a problem. The only issue comes in having pages that redirect or break all together.
