Back links post Panda has become critical to your websites rankings. The one method that I have found that works really well is writing 100% unique content press releases and then popping them onto free pr sites with the proper tagging and a logo. Below I listed not only PR sites, but I tossed in some PR9 sites as well that you can get back links from.
Each site has their own set of rules, regulations, and ability for hyperlinks, images, logos and so much more. Take your time, set up an account on all twenty-press release sites and when you next release some PR-do it FREE! Be smart with your money and by doing this manually, you can also spin the article as many times that you need on various sites. Don't focus get back links can be organic and people love stories to follow on social media. Make sure to post on all of your networks at the same time.
Don't forget that you can also buy high-quality back links and "game the system" this is true. However, by doing so you risk being hit by Google at some point. Developing blogger relationships and outreach to high back link PR sites such as media sites is also highly suggested. At the end of the day it is all about finding your URL a good home for your content and most importantly, your anchor back link for SEO value will be higher organically in most cases.
