I'm sorry, I searched this site, but couldn't find the answer to my question, in spite of it being so trivial.
I'm working on a CMS which get's keywords from end user, which means that they are totally dynamic for each page. I get each keyword separately. What delimiter characters should I use to include those keywords in
<meta name='keywords' element?
Second question is, can I use space in my keywords? For example, can I have this meta tag element:
<meta name='keywords' content='first keywords, second keyword with space, third keyword with space and another space' />
