What one word points to is, page of a content, decide a keyword (long end keyword) .

Keyword of this long end should appear in the following everywhere:

On the caption that the first place is this content page;
In the keyword label that the 2nd place is this content page;
In the content that the 3rd place is this content page: Add in content black, keyword density is increased a little;
it is to appear inside the station to mix everywhere in text of the anchor outside the station.

Had done this everywhere one word, long end keyword is not a problem
