Content not ranking in the USA The content we produce ranks in India. But, since we're trying to expand, we want our content to rank in the US as well, but haven't been really successful.

Regarding the site structure, it's fairly basic. no cctlds, subdomians, or hreflang.

Please suggest:

1. Is cctld must to rank a content in a specific geography? If so, what's better?  

   1. example.com/us
   2. us.example.com
2. Even though the language is English, please suggest possible reasons as to why the content isn't ranking there, despite targeting easy/low search volume keywords
3. If there are other options that show good/immediate results
