Use "Annotation" in FC to add MetaTag???

[BethParker]

Hi, everyone.
I have a customer who asked me to embedd MetaTags into my FinalCutExpress website videos I am making for his website. Can anyone confirm this method for me or suggest a new one? First, customer gives me the search optimized terms to embed. Then, I open the original capture movie files, from top menu "Window">>Show Movie Properties>>Annotation, Dropdown box "Add Annotation" then type in the search terms?
Am I completely off track here? THank you!
