How to find high PR do-follow blogs?

[pro.seods]

hi,

I was looking for some do-follow blogs for my site to comment on.

And I realized that it was so difficult to even find one blog with a high PR. (Eg- PR4, 5 or even 3):eek:

Most of the blogs I found were either no-follow or wanted me to register on them. So I searched up google to find why there are so many no-follow blogs. I found that the number of no-follow blogs have increased due to the increasing spamming by various link builders and people to increase their SERP.
So, I thought I would put up this question on DP and See if I can get any good and informative answers?:rolleyes:

Q1. What is the best and the fastest way to find do-follow blogs?
Q2. IF there is no fast way to do so and then tell me a long or slow but a good way?
Q.3 How can we increase the SERP on google? Can we do it by no-follow?
Q.4 What are the other ways to build link and Boost our SERP on GOOGLE?
Q.5 How can I boost my SERP?
Q.6 Are there any other ways to link building?(except blog commenting, directory submission, article submission, forum posting!);)

Please help me:o

Thank you
