Does the content of each page of the site affect the position of its main page?

Question

Search Engine Optimization

I am making a portfolio website, where each individual work has its own separate page. In theory, I can write a voluminous SEO text for each such separate page. The question is - will the number of such texts on my site as a whole affect the position of the main page in the SERP?
Thanks in advance.

Answer 1

Probably not. But if you refer to the main one in these large articles, then, of course, the main one will slowly move up. Moreover, it is contextual links that are valued.
