I tell you a bit about the best SEO strategies I know for you to follow.
You know, in todays SEO world you cannot just build as many links as you want. You need to build links slowly since Google are trying their best to penalize spam websites to provide quality results. Like for example: If you want to build 1 link this week to an authority/relevant website then you need to build 2 links for the following week, 3, 4 etc. and this is called "Link Velocity". Because Google now look at link velocity as a ranking factor. Once you build 30 links a week then stop, they see it as a negative signal. spend 50% of the time building to your site and 50% building to the pages that link to your site
Create Social Media Accounts like facebook, twitter, google+ etc., then share your interesting content from your blog post to these social media sites. Guest blogging is a perfect link building and branding to your website. Just do it properly cause Google might penalize you by creating too much low quality guest blogging.
over night u cant get a 1 rank. for that u have create backlinks for your website. and that also dofollow links. for that u can do directory submission, social bookmarking, article submission, and first check out the content of your website, content must be unique.
I think blog commenting has a really small impact on these days' SEO strategy. You should put more focus on building links on major high authority sites like Yahoo Answer, Wikipedia, Google +, Facebook, Twitter, Tumblr, Myspace, Pinterest, etc. These sites will help you a lot in the ranking of your site on SERPs.
Fast way: one or two edu maybe one gov and wiki backlinks. Other way: submit to few major bookmarking sites let's say: digg, del.icio.us, reddit...stumleupon, technocrati and few more. Fb,Pint.,Twitt...You don't need 100...or more backlinks..You need few good ones and yoiu must build backlinks constantly. Be regular. Post blog comments or forum on daily basis. And you will not need so much time to get at least pr-1. And of course, you must have as longer as you can content and unique of course...Every time you write article, you look that you have at least 1100-1300 or even longer. The longer is better.
page rank will depends upon the number of quality backlinks and high traffic. Try increase more backlinks and traffic. But Google will update page rank alogorithm is every 3 months. SAo you can wait 3 months definately for PR
