I run a Business Listing Directory website listing local businesses in the area. These businesses are allowed to submit their company description, contact details, URL and other links such as Fb or Twitter.
What happens is that these companies usually copy the description text posted on their own website and paste it into the description on my directory word by word. This obviously creates duplicate content on my site.
My question is then, what sort of impact does this have onto my own SEO and is there any way I could handle this?
