Keyword increase page ranking google?

please give the appropriate answer can keyword increase PR in google.if yes than how much it effects in PR?

I don’t really understand your question. Keywords used where, and in what way?

PageRank (PR) is based on the number and quality of incoming links to your page:

PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. The underlying assumption is that more important websites are likely to receive more links from other websites.

keywords use in website can increase page rank

No. As I’ve said, PageRank is based on incoming links. If you read the article I linked to, you’ll find:

PageRank is Google’s indication of its assessment of the reputation of a webpage: It is non-keyword specific.

your question is not clear. i guess you are trying to say that using keywords in website optimization will help you to increase rank or not? then i would say keywords are not the reason to increase PR as technobear said your inbound quality backlinks will help you to increase PR, and ratio of anchor text in backlinks will help you to get relavant traffic which is also one factor to increase you PR. so use right keywords to optimised your site.

Keywords that you use to optimize a website regarding in hyper text of back links increase ranking of the site in searches only, however to increase page rank good back links, traffic, and on page work are needed.
