Search Engine Optimization

In general, the situation is this. The company had an old website. We made a new one, copied all the articles from there, no redirects were configured, because they did not want to renew the term of the old domain. It turns out that Yandex considers articles stolen? or what other reasons could there be that the site does not want to hit the right requests at all. and what can be done about it?
