Thanks Matt for great reply..

Hello All,

I am working on client website and currently they are targeting One Keywords for multi pages.

As I have search with Allintitle: Search query and Google display around 37 pages of website which carry same keyword in "Title Tags".

I have told to client to change the "Title Tags" but they want that keyword for all relevant pages.

So I want to know is that harm in Search Engine Ranking?

Note: They have not done the link building activities for multi pages with same Keyword, they are using only in "Title Tags" only

Thanks Matt for great reply..
