Meta Tags Keywords in Diferent Languages

A common use for META is to specify keywords that a search engine may use to improve the quality of search results. When several META elements provide language-dependent information about a document, search engines may filter on the lang attribute to display search results using the language preferences of the user. For example:

<-- For speakers of US English -->
"<"meta lang="" name="keywords">en-us" content="vacation, Greece, sunshine">

<-- For speakers of British English -->
"<"meta lang="" name="keywords">en" content="holiday, Greece, sunshine">

<-- For speakers of French -->
"<"meta lang="" name="keywords">fr" content="vacances, Greece, soleil">

<-- For speakers of Portuguese -->
"<"meta lang="pt" " content="ferias, Grecia, sol" name="keywords">
