How does the site rank in search?

Question

Google

Good day, dear masters of their craft.
Today I asked myself a question to pull up seo-optimization. I'm trying to find information and stumble upon some articles. Sometimes the information in the articles diverges. But still I want information from primary sources.
Essence of the question. Maybe someone has links (preferably in Russian) to technical information on ranking sites in Yandex and Google, respectively? Interested in the original source. Thanks in advance for your reply.

Answer 1

If such information existed, it would be possible to manipulate the SERPs by fitting the site to these ranking factors.

Answer 2

Perhaps you are looking for this:

In general, it would be useful to watch the research of SEO specialists themselves, because why experiment if someone has done it before you :)
For example, MOZ found that SEOs prioritize content relevance, link donor quality, and keywords.
