Path context to add page title meta tag

I've created a custom view's page for my users to display a list of all posts, and would like to add their name (but since that may not be possible with my config I've been trying to just add the word "Author") as the page title (metatag). The context path's I've tried include:

1. /users/%
2. users/%
3. http://website.com/users/%
4. /users/1
5. users/1
6. http://website.com/users/1

The result was all the same - a blank page title. I've also been clearing the cache after each context update. After the first three didn't work I started just trying to target the admin user, which also didn't work. Documentation would be great to ensure I'm using the correct path. But until that time, any thoughts/ideas why this isn't working? Have I missed a possible path?
