I want to duplicate the site for another market, how to avoid an SEO ban?

Question

Search Engine Optimization

Hello,
there is a task to make a copy of the current one-page site for the market of another country. Content changes are minimal - other data in the contacts section and that's it.
I am very familiar with seo, I read that duplicate sites can get banned by search engines. How to avoid it? The original site comes out in the first positions for our keywords, we don’t want to lose it out of stupidity.
All the best,
Bob.

Answer 1

Change the content, this will be enough - given that the sites are one-page.
Of course, you can also change classes and IDs through Notepad ++ as a mass replacement, but I think this is paranoia. When changing content, there is nothing to ban you on a one-page site. Yes, and there is no such thing as a seo ban, you can be filtered by the PS for re-optimization, or for a full copy to say that you are a mirror of the site, which is decided by the application after changing the content. So don't worry.

Answer 2

<link rel="canonical" href="http://original.site/duplicated_page.html" />
