Sorry for being unclear about this one.

You put the localization macro in Site Manager -> Settings -> Content -> Metadata -> Page title prefix.

Kentico will resolve this macro when a user browse your site, according to the user culture. If the culture the user is browsing on is not defined in your localization macro, default value will be used, which is the first part in the localization macro.

For example:

{$=Bienvenue sur mon site|en-CA=Welcome to my site|es-ES=Bienvenidos a mi sitio$}

We have three part in this localization macro: The default text (in my case, default site culture is French (Canada)), the English (Canada) text and the Spanish (Spain) text.

I suggest you having this reading. What you look for is the In-place localization macro.

I hope this time is more clear :)
