It is not very good.
It is VERY time consuming and the yield isn't very exciting.
1. Go to Black Hat forums find people that sell high PR backlinks. Find their website in their signature. (So far I haven't found one single website link in a signature or on a profile.)
Put their website links in notepad if you find any.
2. Go to Fiver. Find people that sell high PR banklinks. Look through their comments and find customers that left a backlink to their site. I have not found one single backlink to a customer.
If you find one add it to your list.
3. Type in Google "blog commenting service" “high PR backlinks” “buy
backlinks” “high pr blog comments” “etc.”
Usually SEO companies/providers use this links to rank their own websites.
Add their URLs to your list.
4. Download and run SEO quake. Restart your browser.
5. Look something up in Google and on the right top corner turn off Instant search. Change number of links to 100.
6. Now take the list of URLs and put them into Google one at at time like this:
link:website.com
This is supposed to show you the backlinks to the website. It isn't that simple. It will show you every single page on the website! After you go through those MAYBE you will find a site they have posted a backlink on. It takes a long time to find pages with backlinks.
7. When you find a website you think has a backlink on it, open it in a new browser window. Look in the SEO quake toolbar and it will give you the PR of the page you are on.
I spent about three hours on this and found two PR3 sites.
8. Sign up for SEOMOZ Site Explorer - You have to have a credit card. 30 days free then $99 a month for an in-depth website analysis. I chose not to sign up.
Take your list of high PR sites and post backlinks. He recommends you embed your backlink BUT a lot of blogs block those so look and see if other comments have them.
Code:
<a href="http://www.yoursite.com">YourSite</a>
That's it.
