Welcome to the Q&A Forum

In general, I understand that having duplicate content on your website is a bad thing. But I see a lot of small businesses (specifically dentists in this example) who hire the same company to provide content to their site. They end up with the EXACT same content as other dentists. Here is a good example: http://www.hodnettortho.com/blog/2013/02/valentine’s-day-and-your-teeth-2/ http://www.braces2000.com/blog/2013/02/valentine’s-day-and-your-teeth-2/ http://www.gentledentalak.com/blog/2013/02/valentine’s-day-and-your-teeth/ If you google the title of that blog article you find tons of the same article all over the place. So, overall, doesn't this make the content on these blogs irrelevant? Does this hurt the SEO on these sites at all? What is the value of having completely unique content on your site/blog vs having duplicate content like this?
