Hi, I'm little bit confused. I read some thing about google penguin. Is it bad to use link exchange? Because linkquidator show me that I have a 97% backlinks at critical degree.... and about 80% are backlinks from site which I exchange link. I see a lot of site with PR2+ and 200+ UV/online at the moment and all that site have many exchange link (website with adult content). So, is it good to use exchange links? and if linkquidator say that I have chance to penalty at google 97% should I disavow all backlinks? Thank you for answer
