Start by searching Fiverr for PR9 back links, usually the link packages will be around 10 links and over delivered a bit. I choose the ones with a lot in the backlog and many satisfied customers. Sign up for 1-3 of them, after you get the links be sure to ping them. For $5.00 you won't get direct PR9 back links, but the domains will be high page ranking. Then sign up for a 50,000 free wiki blasts dripfeed here: http://www.blackhatworld.com/blackhat-seo/freebies-giveaways/507101-50-000-free-wiki-links.html Put the links in the wiki blast articles to juice them, and repeat. I only just started doing this, so I'm not sure how well it will work, but wanted to pass it along. Please add any tricks that you have to get good high page rank back links to this thread if you like. Happy New Year!
