There exist meta keywords. And we have those already.
Code:
<meta name="keywords" content="Palace,Chat, Palace Chat, home palace planet palace avatar chat" />
Yup, we do.
However, we could add many more. For example, how about adding there names of the most popular visual/avatar chat services and virtual worlds, Such as Second Life? So that when a person searches for those, we appear somewhere in the list. I don't think it's illegal or anything, so why not?
Other suggestions:
Visual Chat, Virtual Chat, Avatar Chat, Free Chat, Virtual World, Chat Rooms, IMVU
And so on.
Also, some more specific Palace chat keywords, such as: Palace Scripts, Palace Manuals, Palace Help, Palace Tutorials, Palace Chat Software, Palace Chat Downloads, etc.
