I know that this question has been asked before but since that was in the past, I have to ask it again. I am new to website development and I don't need a broad answer, just the important tags that are currently supported and needed.
I came to know that
keywords meta tag is ignored by Google spiders but still some meta tags are supported. So I really just need a short list and some description.
Also isn't meta tags like
PICS still required for content filtering? I am trying to develop a hotel website.
