What is the "Nepot" filter in SEO?

Question

Search Engine Optimization

Guys, what is the Nepot filter in a nutshell, and what is it for.
And yes, I already googled , but everyone writes in their own way, I want to hear your opinion.

Answer 1

Well, for example, when a culinary site (donor) links to a site about reinforced concrete products, Yandex begins to suspect something. That's what gives the filter "nepot". In short, the theme must be at least remotely consistent.
