Hi, Does any one has any good keyword to search in google or yahoo to find blogs which allow us to comment them ?
Sure here is google's blog search>>http://blogsearch.google.com/ and Technorati which is the leading social blogging site which has a search also post your blog their if you have one>> http://technorati.com/ Now if your looking for do follow blogs to post on I would recommend a do follow directory such as>> http://www.dofollowblogs.com/index.php?c=0 <<now the problem with this is I have been alerted by dp members that the majority are do follow though there seems to be some that switched back to no follow so you may want to double check before commenting anyway this should give you a couple million blogs to choose from.
You can use some dofollow search engines to make it easier for you. Use this list to find the popular ones You can search for 'keywordluv', inurl:ifollow, inurl:ucomment or ifollowgreen.gif (and other colors).
You can check my signature for that. I have built a huge do-follow blog list. I got many replies back too you can try if you want to.
I found this thread very useful, as using seo quake allows you to sort by pr and NoDoFollow lets you check the comments to see if they NoFollow http://forums.digitalpoint.com/showthread.php?t=1246270
