@cheapseoserviceJan 21.2016 — #Such a high percentage of exact match text backlinks is definitely the reason for the decrease of your rankings. Search engines may have taken your backlinks for link building abuse in terms of massive submission to content farms, or your site may have been "infected" with some low quality and irrelevant toxic links, and this caused unwelcome interest from the Google Penguin radar. Check your backlink profile for toxic links first of all.
