Multilingual Site with 2 Separate domains and hand-translated

[khi5]

I have 2 separate domains: .com & .jp 
I am having a professional translator translate the English written material from .com. However, the .jp will have same pictures and videos that I have on the .com which means alt tags are in English and video titles are in English. I have some dynamic pages where I use Google Translate and those pages I place as "no index follow" to avoid duplicate issues and they are not very important pages for me any way.

Question: since I am doing a proper translating - no machines involved - can I leave pages as is or should I include any format of these:

1. ISO language codes
   2) www.example/com/” />

Even though hand translated, the translation will probably be 85% similar to that if I used Google Translate. Will that potentially be seen as duplicate content or not at all since I have not used the Google Translate tool? I wonder from which angle Google analyses this.

Thank you,

Deinitely make sure to use the hreflang element. And it was a wise choice to have your pages professionally translated.

More information on multiple languages and SEO here.

The hreflang element is actually meant to help you avoid duplicate content issues when it comes to content in different languages.

thx, Travis. How do I tell my web developers what to do? Place this across every page on my English version: www.example/com/” />  - even though some pages may not be on my .jp site? I am not a programmer and not techy so if you can share how I present this to my web guys that would be appreciated.

I read the article now. Apologies for me rushing to ask further. Good answer. That article covers it all well

You would use this code in the head . This should be done for each page. Such as:

I'm not sure if you plan on redirecting people based upon location. There's a lot more about this subject here.

Thank you. Please be sure to read the information at the second link I posted. It looks like it's written using kana.
