Regarding SEO and pages vs post categories.

My website is http://www.brazilianjiujitsu.ie
In my nav bar, I have a few tabs (underlined red in the screenshot) that are ‘posts’ that assigned into a category (either competitions, seminars or blog)

But is it possible to instead have a dedicated page for each i.e a competition page, a seminar page, and a blog page, instead of the posts and categories method?

The reason I ask this is I’m wondering would it benefit my SEO ranking if someone searches for “BJJ competitions” would my ‘competitions page’ rank higher than a ‘competitions post’ with an assigned category.

I hope I articulated that clearly enough lol, I just want to make it easier for people to find my listings for competitions, etc.

Warm Regards,
Shane.
