Ok so I am thinking of trying out the new Disavow tool on a couple of my penguin-affected websites. I have an enormous amount of crap backlinks that I built pre-penguin using Xrumer and scrapebox direct to my websites that need to go. I have a few questions before I start removing links though. Here are my questions: What is the best way to gather my backlinks? Should I be using webmaster tools? I unfortunately don't have a premium ahrefs or seomoz (opensiteexplorer) account. I tried using scrapebox to scrape my backlinks but I didn't have much luck. How should I determine what is a "bad" link? I will probably be using scrapebox or whatever other software you guys recommend to get this data. I assume i should look at the page's PR (not domain), number of outbound links and maybe number of inbound links? I don't think my websites got manually reviewed I was just hit by the algo. This tool isn't just for manual reviews is it? Has anyone had success using it? I just want to try it on a few of my websites and I'll happily post my results. I hear it takes about a month for big G to take the disavowed links into consideration is this true? Thank you so much for your help!
