How can i include META keyword that i’ve defined backend content editor’s META tab ?
if you’ve already defiend them under Resouces => Manage META tags...which I presume you have from your questions. In the dcuments settings under META Tags just click on the metatags you want in the page (USE control for more than 1 like a multi select)
