Can anyone expalin clearly about Keyword density, Keyword Stuffing, Keywords tag, Keyword research, Keyword stacking, Keyword prominence, Keyword proximity? I had studied from SEO Guides but i can't understand it very clear....
Maybe you need to ask more specific questions? Each of those topics could require a pretty lengthy reply to cover. What do you already understand about, say, keyword density? If we knew that, we might be able to give a more relevant reply.
The short story about the keyword meta tag is that it is really not very relevant to search engines anymore. For the most part, the keyword meta tag is ignored due to many webmasters flooding the tag with way too many keywords (keyword stuffing). Like was said before, you've left the question very broad and it makes it very difficult to respond.
