This is my website, how can I improve its PR? I have back links. I submitted it in different directories and also posted two articles. what else can I do?
not sure how many directories you submitted to and how many backlinks you built. but 2 article submission, few directory submission will not give you much of a PR. you get your PR based on the PR of the sites you are getting links form. more backlinks you have, higher your PR will be. so just give up and sit there waiting till next PR update, keep building backlinks
Do a search for some .edu blogs... get some backlinks that way, also you can probably find lists of high PR links around the web. Keep in mind PR isn't updated daily either, so don't expect a change overnight
Do seo on your site, i did it on mine 2 weeks ago and google updated my site 2 days ago and now im getting around 2k visitors a day, but before i did seo i only was receiving around 1-4 visitors a day
Improve backlinks It would be difficult for you to get a high PR number on a site with very few content/articles. Focus to high pr sites with do follow on their attribute links.
Please don't expect high PR through article and directory submissions. You need to get links from high PR sites in order to improve PR.
Build backlinks from dofollow blogs.I suggest you to submit all your articles to blog engage - a do follow blog directory.
Spy on your competition that have high PR and see similar pages to learn what advantages they have compared to your site.
