Are those your articles? They seem duplicates to me as there are lots of other sites with the very same articles (at least first two). If not you should use your own content, this is not only unethical also you may get penalized by Google and duplicate content won't help you in long term. Meta informations are complete. User friendly links are ok. Good luck.
