I have been getting some PR6, PR5 and lots of 4's to stick in many do follow blogs. However the the blogs are not relevant to my site. Are these of any value, will they pass link juice?
When you say 'not very relevant' - to what extent? e.g. what is your website about and what's the linking high PR website about?
Yes, they are good unless they are link farms. Not as good as relevant sites of course. But you should not get too many irrelevant links, that might produce a strange link pattern.
The blogs do not have "no follow tags" I have even seen some blogs that have a " we follow" text by the comment area.
Are you being sarcastic? What I was trying to say, is that I thought blog comments do not have any effect on PR and SERP, and don't actually count as a backlink.
Sarcastic? No.. if they are do follow blogs they should count as a backlinks I do not see why they would not? I check the whole page with a tool and it shows as do follow. And the "we follow" statement is "For more background on the “I-Follow†movement, check out Randa Clay " http://randaclay.com/blog/i-follow/
