is this not a duplication for google?
By “positioning”, did you mean how high it displays on Google Search results?
If so, it really depends on how you’ve made the page.
Depending on your theme, if you’ve created a static page and just added post list on it without turning it into an actual archive page of a taxonomy, it may lack the necessary element attributes for SEO.
But I’m not exactly sure what you mean by “positioning” or “duplication for google”. We may need further clarification about this.
