Right method of keyword targeting is to target each unique keyword on every page. Neither two keywords should be targeted on single page nor should a single keyword be targeted on two different pages. This practice can confuse search engine crawlers while distributing importance with keyword.

For example: If your keyword is “Personal Loan”, you can target “Personal Loans” or other associated with “Personal Loan and Personal Loans” but should not target “Home Loan and Home Loans”.
