Does making a copy of website harm my SEO?

[AlirezaHamidian]

We have made a demo server on a different domain than our main website domain to test new features on it before updating codes on the main domain. Does it hurt our SEO activities?

Thanks Everybody

You don't want a copy of your website out there. Ask your developers to block that demo server in robots.txt, and consider putting a password on it as well just for extra security.

Hi Armin,

Let me give you an idea on what could happen, if Google finds you development/ staging site what happened in a case I saw happen is that the site lost over 40% of traffic for 2-3 months until it was fixed. Costing the site a couple of million visits, guess what that did to the revenue ;-).

Edit: a couple of million visits, not money ;-).
