Some Guidelines On How to Get High PR Backlinks

You need to check all website blogs for the no-follow attribute on their comment url links, before posting your comments and links, this becauce you need to avoid wasting your time. The easiest way to check for a no-follow attribute is to view the code source of a webpage and scroll to the comments coding (make sure there’s actually a comment on the page). In the hyperlink code for the comment, if it says rel=”no follow” then the link is no-follow.
Even if the blog is on a do-follow list, it is essential you check if the blog is do-follow. The reason being these lists are often never updated and were current at the time of being posted. Webmasters can change their blog to no-follow with a simple plug in so the best is to check every website.

Google Want links, but what kind of links?

Google with a tutorial on inbound links. It says basically what SEO experts have been saying for years: content and inbound links are most important, and in that order.
Just because it’s old news doesn’t mean it’s bad news. Google’s had a real history of silence on the SEO side of things, and experts were often left to theorize and test—and worse, try to game. Google sent a pretty loud signal this time last year by hitting the PageRanks of paid directories, a move seeming to confirm basic white-hat SEO tactics. The virtues of naturally gained, editorial inbound links and directly denounces links appear “spammy,” or not “merit-based.”
One of the strongest ranking factors on a site is the site's content. Additionally, perhaps a site is also linked from three sources -- however, one inbound link is from a spammy site. As far as Google is concerned, we want only the two quality inbound links to contribute to the PageRank signal in our ranking.

Given the user's query, over 200 signals (including the analysis of the site's content and inbound links as mentioned above) are applied to return the most relevant results to the user.

Here are four bullet points on how to earn merit-based links, paraphrased below:
• Start a site-related blog, writing or video, research or entertainment.
• Be interesting. Be a teacher.
• Participate in the community surrounding your industry—social media, blog comments, user reviews.
• Provide useful products or services.

In short: content, content, content, a little participation, and the links will come.
