No. Traffic will not help increase your Page Rank. To increase your PR, you need to continue build backlinks preferably relevant links. You also need to get links from dofollow sites and have high page rank.

If I were you, don't much focus on increasing your site's page rank. It would still be better to focus more on increasing your keyword rankings in serp.

The main think that you shoud do to improve your website's TBPR is to increase quality links and this way you can not only get a good PR but also good SERP.
Traffic has nothing to do with either SERP or PR

Back links will result your site to increase your page rank and also that to quality back links will gain you more traffic. Thanks for sharing..

I agree with the others, try to get back links from good credible sites; this is what will help you get better page rank.

if you want to get a higher page rank you want to post your site on as many places as you can e.g forums in your sig the more posts you do on high page rank site the higher page rank you get.

Higher traffic not increase page rank but if site have good back links with high page rank they affected to page rank.

Traffic levels effect a sites domain strength indirectly. The more searches for a domain name the stronger it is. The better the CTR to a site from SERPs, the higher the ranking for that search term.

So yes, traffic volumes do affect SERPs position. Not so much Page Rank.

on your trafiice not increseing your page rank it depends on your content .

yes, and i have good experience of it.
one of my inner page has not any back link from other domains and that page is ranking well on SERP.

in last PR update, i got one PR for that page and important point is that page has not any back link.
only fresh content and traffic is there for that page. so well optimization and fresh content can generate traffic and continues traffic can give us PR.
