Thats a huge mistake.
If this includes some authority directories (Ezine, GoArticles) build some .edu backlinks to them. You cant spam same article anymore... New algo do not allow this.
I think you are affected by Google new algorithm.And your main and big mistake is submitting one article to 200 site.Now just try to build some very good backlink and some .edu link.I think you will recover your position.Best of luck :dog_walk1
To how many article sites should he have submitted the article?
