So before I go into repeating what is already readily available online, I just wanted to say this is much more than just a blog commenting tool that most people know of it as. It also has somewhat of a reputation of being bad because of the days of penguin and panda. With that said this tool can scrape and perform tasks lots of new tools cannot and is still relevant even to completely white hat strategies such as for outreach to potential owners to sell your services etc...
Because I feel like repeating or giving information that is already been discussed in really great detail it would almost be like beating a dead dog, no I don't beat dogs! It's an old saying. So I would recommend checking out this YouTube Channel for specifics of what ScrapeBox can do!
