Google Disavow Tool

[EcomLkwd]

Some background:  My rankings have been wildly fluctuating for the past few months for no apparent reason. When I inquired about this, many people said that even though I haven't received any penalty notice, I was probably affected by penguin. (http://moz.com/community/q/ranking-fluctuations)

I recently did a link detox by LinkRemovalTools and it gave me a list of all my links,

2% were toxic and 51% were suspiscious.

Should I simply disavow the 2%? There are many sites where is no contact info.

I would try to get them manually removed before using the tool (Google recommends this). If you can't find any contact info, try doing a lookup on whois or try entering site:domain.com "@" for emails or site:domain.com "Ph" in Google.  Good luck!

I agree that doing all you can to find contact details is the best way to go. Another way to find people is via social media accounts.
