Article indexing and plagiarism?

Question

Search Engine Optimization

Comrades, tell me plz. Is it enough to index a unique article on the site so that the original source is assigned to it?

Googlers at the conference convinced that indexing is enough to fix the primary source, for content of any type.
In practice, no. According to our observation, an authoritative resource can be given priority.

webmaster.yandex.ru > Site content > Original texts

Answer 3

Original texts do not protect against plagiarism at all. Whoever indexed faster is right.
