If you want to add attribute from admin side follow these steps :

Create a new attribute :

--> go to stores -> attributes -> product (http://prntscr.com/nf5a9w)
--> create a new attrbiute (http://prntscr.com/nf5aoa)
--> visible on catelog page must be yes (http://prntscr.com/nf5fn1)

Keep it in attribute set :

--> go to stores -> attributes -> Attribute set  (http://prntscr.com/nf58xz)
--> select your attribute set or default (http://prntscr.com/nf594u)
--> drag and drop your attribute to any group (http://prntscr.com/nf59ur)
