i want to change the url of one of my pages

[suprskin]

I am trying to show an all blogs page. I have 5 different blogs. products, skin, health, ingredients and fitness however there is no page that will show them all. I created a page that now links to each blog but the url is /pages/blogs. I want to change this url to show /blogs.

it is only allowing me to change what comes after /pages/ 

I also am wanting to change the structure of the way the products are shown in the url in order to boost my seo, I am hoping the way you change the url for the /pages/blogs will be the same fix
