Question here, but first the lead in. As you all know, 301 redirects don't pass on 100% of link juice. I've set up my site using htaccess to redirect all non-ww to www and redirect all URLs to have a trailing slash. FYI, the preferred domain is selected in WMT and canonical URLs appear in the head section of all pages. So now what happens when sites that link to mine don't include either the www or the trailing slash, which is actually quite common? Of course, asking the site own to correct the link is ideal, but that's not always possible. So if thousands of links on external sites are linking to http://www.site.com instead of http://www.site.com/, won't lots of link juice get lost in redirection? I can't think of anything more I can do to the URLs to reduce duplicate content and juice dilution. Thoughts? Kevin

I am working on a language teaching site for Chinese speakers learning English. I consider myself above average when it comes to basic SEO issues, but all I know here is that Google doesn't like multiple languages on a single page. Without getting into too many details, both Chinese and English text will appear on the same page with links, tags, phonetic spellings, etc. I'm hoping someone here knows the science about using the lang="zh" xml:lang="zh" attributes within text and the effects on ranking for text within the declarations. And it'd be great if there was clarification on the link juice passed using the hreflang attribute for both internal and external links. Also, of course, any info on using both English and Chinese characters in the URL would be most helpful. A heads up on any other language specific SEO issues would also be much appreciated. My goal is to get the most out of both languages per page in terms of ranking.
