Also it is very important that how often you are refreshing your contents.I am suggesting you to do the works for a visitor to keep in your site.For example keeping the related posts will lead the user to refer that posts too.So that you can increase the page views.Try to give the up to date contents on your website.
The one of the most important factor is try to include the keywords inside your posts.For example here I am writing about how to increase google page rank.I am trying to include the keywords in my post and I am always adding that google page rank.It will make a keyword rich site ,and make your site on first on the google search.Note that should not add keywords in a huge amount comparing your content.IF you do so,google will skip that page fully.
Google also concentrates on unique and fresh contents.Copying and pasting contents from another site will not make you to rank a high in google.So you your site should have unique contents,which will pull your site to the first list.
Once you reach on the top of the list it is very easy to maintain the rank by a reduced risk.Comment about your articles and your site on other related sites makes the back links to your site.
