Same keyword on several pages

I have a site that I optimized to get traffic from one specific keyword, and I am starting to see the results from that now. What I am wondering is:

Will I rank higher in the SEPRS for that keyword if I optimize all the sites pages for that single keyword, or is that a waste of space? Is it better to optimize each page of the site for an individual keyword?

 

Optimise each page for different keywords - i.e. keywords relevant to the page's content.

 

so basiclly no, you will just be diluting your web pages

 

If you have a site optimized for a single keyword, it is best to optimize other pages for keyword phrases including that very keyword. This both emphases your theme and adds "the Long Tail" to your content.

 

in this way you'll creat inter pages competition for ranking in serp.

 

I agree. Targetting only one keyword on one page will not get nearly as many results from google as you can. My suggestion is to just make a few more pages using the keyword.

 

I think you are better off using different keywords for different pages, i.e select keywords relevant to the page content.
