the list of links pointing from penalized sites like you mentioned? Amazing post Navneet, This post is an effective package to learn "How to Disavow", "Why to Disavow" . You explained back links analysis tools effectively, I personally feel that Google Webmaster and Open Site Explorer are the most efficient tools to check back links and much more than that. You warned about disavow links that we must be assured that the link is bad and we need to disavow it, otherwise on some occasion we might loose good links because of bad decision making. Navneet thanks for the excellent post. I usually use http://www.link-assistant.com/ to check quality links. The software is not free of charge but doing a great job. and regardless of the program i think it is about time that Google will make a drastic change like this to eradicate the spam inexperienced webmasters. Nice post Navneet and some interesting thoughts on the redirecting routes around Penguin. Too much of the talk after the Disavow tool was launched was how it made recoveries easy, though untrained website owners may have judged that to mean they should just submit all their links to Google without contemplating the fact that they might actually still be helping them. Before they know it they've lost all that value and don't understand why. It's great that you've highlighted that even some links which appear 'disavowable' shouldn't necessarily be included. I definitely agree with you Adam about the wrong product for the wrong
