Do I need to create a separate page of the site for contacts?

Question

Search Engine Optimization

Hello
We are making a portfolio website. Initially, it was conceived as a landing page that hosts everything, including the feedback form and contacts.
The question arose whether a separate page with contacts is needed, in terms of seo. Or is it enough to place a feedback form and contacts on the main page?
I don’t understand this topic yet, I met both options with competitors, it became interesting which is better and why.

Answer 1

From an SEO standpoint, search engines don't like one-pagers at all.
And given that the contact page does not affect promotion in any way, even with the second page, it will still be a one-pager.
And regarding the contact page, generally pofik.
Make it in the basement on the main one and put the necessary markup.
