I have much conflicting information about how to format my keywords.
<meta name="keywords" content=".......">
Some people say to separate the list with commas, others say comma plus a space. What about phrases, two or three words?
Some people say to separate words in domain name with hyphens, so the search engines can find them. I see many domain names that are strung together as one long word. Which is more effective, or does it matter?
Please discuss. Thanks.
