100% Is virtually impossible, afaik, MOZ accounts for all of the domain's keywords and their CTR. To have 100% visibility, you'd have to rank on the 1st-3rd position for each keyword that you rank for, which is impossible. Even if you optimize your website just for 1 keyword and manage to get it to the 1st position, you'll still grab some keyword on the way and you'll have your own 'long tail', keywords, for which you rank beyond 20th position.
