Should home, category, and article pages have different keywords?

[inmatrix]

1) If not, will hurt the keywords PR?

2) Then I post a new article, the article will show on the home page (at least the title of the article will show on home page).So the keyword in this title count on home page or count on category page or count on the article page?

3) If i have set the "Use noindex for Categories", I don't need to consider the keywords PR problem on category page, do I?

Could be we don't know what you're asking.

Are you running a CMS, or crafting these pages by hand?

The answer below is from Warrior. But i still so confused.

"1) No, can operate in the same keywords, and that's means you go rank higher on google to these keywords.
2) All pages, if at on all.
3) Don't, noindex, means Google or Search Bots don't go see or visit this page."

About the "If the home page and the category pages and the article pages operate the different keywords？, will hurt the keywords PR? " I mean PR not focus something, i am a newbie, dont know how exactly express this situation.

If the keyword has valid reason to be in the title and article, it is also valid on the sub cat pages. However, don't make the mistake of stuffing keywords into everything as that will give a much lower result than proper use.

I heard so many people said on the home page we must operate the major keyword and on the category we operarte the minor keyword and operate the Long Tail Keyword in the article. Otherwise PR diluted something. (For example, the category cant also operate the same major keyword with homepage, otherwise they will affect each other. Not good to rank.)
