Is the snippet made automatically by Yandex and Google?

Question

HTML

Read about snippets.
Do I understand correctly that Yandex and Google will choose information about the site for the snippet?
I can only contribute to this with a description meta tag?
Thank you!

Yes, that's right, he can choose a snippet from discription if he doesn't like the text on the page, or there is not enough of it / there won't be / it won't contain the necessary occurrences of words, etc.
