I have a number of websites that were struck down by the mighty penguin over the last little while. I also have a feeling that I may have accidentally built some low quality links by mistake in pursuit of building strong ones for my new websites as well. Anyways I am looking for some tips on how I can clean up these profiles. I just recently heard of "link detox" but if I have to pay $40 per website I think that is too expensive. Do you think it is enough to simply download my links from Google Webmaster Tools, run the links through scrapebox PR check, use scrapebox OBL checker and then finally disavow any domains that are lower than 1 and OBL higher than say 50? Is it enough to disavow a whole domain (does it have the same effect?) or do I have to disavow the exact URL? I unfortunately don't have ahrefs, majestic seo or open site explorer paid accounts. Webmaster tools seems to be my best option unless someone has a better suggestion. Is it worth using the disavow tool? Has anyone had a resounding success with it yet? Some of my older website have terrible xrumer spammed link profiles. I really appreciate any help - I figure I may as well get the ball rolling on removing these nasty links because I'm sure it will take a while.
