Ranking in India at 1st in SERP but does not ranking anywhere in USA?

Question

We created some new pages six months ago, targeting the USA. After two months, these pages started ranking on the first page in the USA.

However, after Google's Spam Update on December 20, 2024, their rankings dropped completely, and they are no longer appearing in SERP for the USA. Surprisingly, they are now ranking 1st in India.

Additionally, when searching for keyword + brand name, these pages do not appear in the SERP. Our domain hosting is USA-based.

I conducted an in-depth analysis, and everything appears fine—no spam backlinks, proper content optimization, and correct interlinking.

How can we regain keyword rankings in the USA? I am looking for a logical, non-generic solution.

If anyone need any data like url or keyword, i will share.
