Will the new SEO module allow :
1. To set the language and localization you want for a page. Example : English language for UK / English language for US / English language for those who live in Poland / Polish language for Germany region etc.
( because Google webmaster tools allows you to target only 1 country with your site or all of them by not specifying anything, so if you don't target the whole site to a specific region you should do this targeting for each page right ?)
2. Allow pages in shop and other modules to be tagged with language and region zones ? For example you want a product in shop module to be sold for French people in French language and in German language for German people.
Also since the menu of the shop module & other modules are fixed in one language, how are you going to make a multilingual site ?
Will the SEO module allow : Subdirectories with gTLDs example.com/de/
Your site has no hreflang tags.
Google uses hreflang tags to match the user's language preference to the right variation of your pages.
