is this not a duplication for google?
To clarify:
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.
