I have a couple of links Penguin penalized. One is in a blog and the other in a news site. They have been there a couple of years and nothing has hurt it now penguin said that the site is being penalized for these links. I check the links with the disavow tool and it said they were good....did a copy duplicate to see if someone copy and this might be the problem and nothing...can someone just give me a suggestion as too why they might be doing this. The articles are good and pertain to the site they are on and only one anchor text keyword link in the article back to the original site.
