Duplicate store (subdomain) not ranking

[grocare]

I have a store ( www.grocare.com ) and I made a duplicate store recently ( in.grocare.com ) for a different region. Both have different currencies and target different regions. I even targeted the new store ( in.grocare.com ) to that particular country in google search console. They both have different href lang tags to mark different regions too. Now its been a month since this has been done.  But the new store is not ranking in the region. The old one is still ranking and I have to redirect the traffic from old to new based on IP. 
I thought making a new store and targeting specifically would help with rankings. Am i doing something wrong here?

It's all good.

Yeap, both hreflang tags in both pages.
Think it this way:

• One hreflang is telling the actual language of the page.
• The other is telling that there is a version in other language.

Best luck!

Ah! You're right! Thank you so much.

The IN version was pointing to the EN version. As per Hreflang generator - Aleyda Solis I have to add this to the head area

https://www.grocare.com" hreflang="en-us" />

https://in.grocare.com" hreflang="en-in" />

The only doubt i have now,  is whether I should add both these tags on both sites? Or should the EN version be added on EN site and IN on IN site?

Hi there,

The biggest issue here is that hreflangs aren't set up correctly. As you are only pointing the IN version to the EN version.
Keep in mind that there have to be two tags, pointing out both ways.

As always, when it comes to international, these resources come handy:
Hreflang generator - Aleyda Solis International SEO - Moz Learning Center The Guide to International Website Expansion: Hreflang, ccTLDs, & More! - Moz Blog The International SEO Checklist - Moz Blog

Best luck.
Hope it helps.
