Meta and keywords don't works

I've set some alias in the apposite sef advance module and I've set also for everyone some keywords and description but they don't works ,why ? Always in the page meta appears the key and the description set in general site configuration,

thanks a lot

Are you sure you setup the alias correctly?

i don't know , i fill al forms in the alias page, the url rewriting work well but not meta .

As I have wrote in another post , I've saw that the articles don't show meta and keywords well, i don't use alias for each article off course , i write down for each article keywords and description in the joomla apposite forms but in the article page returns always global meta description and keywords it's a big problem for seo indexing
