How does the uniqueness of site texts affect ranking?

Question

Search Engine Optimization

On our site, each service is accompanied by a text (~1000-2000 characters). These lyrics were written personally by the director, so in some way they are 99% unique.
Now they are actively engaged in promotion and I decided to check these texts through an anti-plagiarizer. It turned out that almost all of them had <10% uniqueness.
I added our website to the exception, but I saw that our text is found in a lot of places ... in all sorts of directories. Naked copypasta.
Apparently someone tried to promote the site before. And he sculpted our texts wherever possible.
It turns out a paradox - the texts were written from scratch and initially had almost one hundred percent uniqueness, but due to placement in service catalogs, the percentage of uniqueness dropped to zero.
This is very bad?
Since the texts were written specifically for the site, when promoting them, they should not be placed anywhere, so as not to lose in uniqueness? Or does it not affect rankings?

Answer 1

Everything depends on the situation. If now the positions of landing pages with these texts are ranked low, then it is worth rewriting the texts, improving them, supplementing them with relevant content.
If the site sits in the top, texts are gradually pulled away from it, in principle, this is not very scary. The main thing is to keep the content relevant. Chasing all the time for 100% uniqueness is not necessary.

Answer 2

Kill it.
Take and strengthen each article on your site with new 3-5 texts.
In sense strengthen each request. As a result, cover the uncovered semantics and get traffic and positions.

Answer 3

Yes, it’s definitely a copy-paste here) it’s just that if a unique text is added to a site indexed by Yandex or Google, then first of all the search engine issues requests to the site where the unique content was first added and plagiarism shows this ..
