Yes, it is possible but it’s take many efforts and time. Here is the step you must follow and boost your site PR. 1. Get Incoming Links from High Quality Related Sites 2. Remember to Use SEO Techniques 3. Write Original Content 4. Don't Go Link Crazy 5. Write eye caching Content Also, I have 700 authority site list, included .edu which is allow getting quality links from there. Just PM me if you want authority site list.
Right...now one has to think about building sites like mentioned above...if its possible for you then yes pr8 is possible...if you want it fairly quickly than like 4-5 years then see bing.com, if you have enough bucks for that much marketing and manage to get tons of traffic and gazillion links in short span then you can reach there within a year as well
Nothing is impossible in seo field, if you are really targeting pr8 for your website then i will advice you to get baclinks from .edu or .gov sites that have pr7 or pr8, 1 or 2 quality .gov or .edu backlinks can fulfill your wish of getting pr8.
And money! Lots of them. No one should think for a second that they can build, let's say, a link bait strategy in a very competitive field, without spending a dime
PR development is all about: Number of website traffic + Quality of incoming links = Increased PR Example: Twitter (PR 9/1) CNN (10/10 and of course, Google (10/10) Get more traffic and relevant backlinks if you want improved PR. Enjoy, eIDSeller
Having a PR rank for your site is easy but well for me if you reached already the PR4 rank for your site, its really hard and there will be a lot of work to improve and apply, so that you can gain a PR rank.
My site is currently PR1... and I would be happy to see it PR3 by this year end.... my target is to reach till PR6... after that I think its next to impossible for a single person working part time n his site.
