Is the page indexed on a new one with unique text?

Question

Search Engine Optimization

Welcome all! The following question: If I initially create a page with non-unique text (plagiarism) on the site and the page goes into the search for over9000 position, then after changing the same text to 100% unique, the search hides the new text, updating its uniqueness, so to speak? Or do you need to silence the URL and only put unique text on the new URL?
Those. I will explain on the concept: There is a site, for the visual perception of its layout, non-unique texts are thrown on its pages. Later, if I replace the non-unique text with a unique one, will the page indicators be changed during the AP of the search engine, or due to the fact that there was originally plagiarism on the page - will it be at the bottom before retirement?
Thanks ^_^

Answer 1

You can do this, but it's better to prevent such pages from being indexed before replacing the text with a unique one.

Answer 2

it is possible, but it is too long process
When developing a new site on hosting, in order to show the result to the customer, it is better to use password access before launching the site,
