Hi I am going to outsource article writing service to my micro niche site. But I am worried my entire articles are not rewritten from scraped article. Is there any ways I can find those articles are not rewrite (other than copyspace). Also I want to know from your experience Google has the intelligence to find the rewritten article from scrapped one. Also I am looking for SEO service provider who can give guarantee 1st page ranking with money back. If you know any one pls let me know.
