We have a very successful website that has been up for a number of years (www.comellaortho.com). We rank high in the natural rankings for that site.
A few months ago, we started seeing patients in another nearby city. I purchased a new domain name, www.dansvilleortho.com, and had our web company duplicate the website under the new domain name. The reality is that the content on these two sites are nearly identical. Some of the pages are different; for example, there are fewer pages on the new site. But the pages that do exist are nearly identical.
My question is: Can having similar content on my company's two sites hurt our rankings?
Based on what I've read thus far, I believe the answer is "Yes". However, I'm curious how bad this may hurt us.
I'm not as worried about the new site (dansvilleortho.com) because our competition in that city is slim to none. But I AM worried about harming the original site/business (comellaortho.com).
Which site(s) rankings may be affected by this, and if so, how bad?
Thank you.
