Since search engines take a clue from content for indexing and ranking a website to great extent, it is important to provide highly focused contents. This is applicable to both on page and off page contents.

On page content usually stay as it is with minor changes here and there. The difficulty is greater since in spite of writing unique content all the time on still has to be on one track for a focused results of targeted search terms.
