How to add multi language web site to the Webmasters

[Peda]

I'm confused about adding my multi language site (2 languages) to the Google Webmasters.

 

For instance:

1) http://www.mysite.com/

2) http://mysite.com/

3) http://www.mysite.com/en/

4) http://www.mysite.com/fr/

 

- Do I have to add these 4 addresses to the Google Webmasters (Search Console)?

- Do I have to add my sitemap .xml files for each of them? Or only for main address (http://www.mysite.com/)

- Do I have to use 301 redirections? (Or enabling Canonical URLs is enough?)

- Do I have to use "hreflang" for each language and regional URLs?

- If default language is FR, entering "http://www.mysite.com/" and "http://www.mysite.com/fr/" goes the same pages. Are we going to encounter duplicate content issues?

 

 

Thanks in advance

You can add all the following pages to Google webmaster tool :

http://www.mysite.com/fr/

http://www.mysite.com

 

You can add all URLs in same sitemap as you know that sitemap can have 50k urls.

You can have 301 or canonical tag if you have duplicate issues

Yes you should use hreflang for each url

If both urls have same content but one in english and another one in french then absolutely there would be duplicate issue.
