Can any one tell me What should i do to increase page rank for my site? I am also looking for ways to increase natural traffic on my site.

Use google adwords! This is Can help you!

I never thought about this one actually, but it might help. Write a press release about your company doing something that is news worthy. If some news organizations, sites or blogs within your industry take note and publish, it will be a worthy link back.

Page Rank is determined from other sites linking to you. Natural rank, or Organic Keywords is something that search engines LOVE. Rather than paying for the AdWords, restructure the words on your pages to focus in on your demographic. Remember, you don't have to have all your keywords on one page, you're better having specific pages for specific keywords and then a shared coloboration on the main pages of the site.

The advantage is that you not only get the Organic listing for your domain name, but you'll likely also get a page (or two) from within your site that will show up and be INDENTED. The eyes naturally attract to information that stands out, and if you have a list of domains/links all in one neat left aligned list and you get a link that's indented by an inch, your eyes move to that listing FIRST - skipping past adwords and any other links ranked above you.

Do a search for "x-cart hosting" in google and you'll see what I mean. Your eyes will naturally draw toward one of my links rather than a competitor

You can use Google AdWords or put link in your site that are already ranked. It helps big time.

Try to have a good sync with Off page and On site SEO.. It should help you

Press releases have worked great for us.

Having natural web traffic is definitely better than simply sticking to the PR boost of the sites. A lot of the top Google ranking websites could have low or moderate PageRank scores but since they are powered by a lot of one way quality backlinks, so their traffic and web ranks have increased considerably. Links are definitely helpful, especially from the connected pages and websites.

As Conor mentioned, higher SERPS and increased traffic comes primarily from matching keywords to pages that address those keywords. Content that is relevant to the search query is the 'key' in keyword.

I think article submission also is the best one way to increase a page rank.
