Linking verbs do not express action. Instead, they connect the subject of the verb to additional information about the subject.

For example,
"Keila is a shopaholic."
Ising isn't something that Keila can do. Is connects the subject, Keila, to additional information about her, that she will soon have a huge credit card bill to pay.

So based off of that, which do you think it is?
