Well I share a secret here, You can do it in google. What you need to do is search when you have time. For an example try this query in Google. site:.com “Allowed HTML tags:<a>†your keyword You must get related blog comments. Good luck Blog.
You are welcome for both. Another thing is getting newest pages in the web sites or blog. Most of pages in past 3-4 months have a PR according to PR Update. There was a PR update in june 2009, so find pages in 2009 june. You will get a lot of blog pages. Alse we can make a comment in new pages rather than very old pages. This is the example for that site:.com “Allowed HTML tags:<a>†2009 june see Results 1 - 10 of about 980,000 for site:.com “Allowed HTML tags:<a>†2009 june. (0.34 seconds) in google You will find a lot of blog pages with high PR, Good luck Blog.
i have recently posted a small list of dofollow blogs on my blog. There is even one with pr6. http://www.freelancer-online.com/archives/101
It's not always like that. Try searching keyword "Enter YourName@YourKeywords in the Name field to take advantage."
i use site:.com inurl:blog "keyword" for search relevant blogs although it shows in large number of blogs but i separate that fits to my needs
Thats a great tip but I pity any site owner who blog shows up with that search term. Also check to see if the blogs are do follow or you'll be wasting your time.
