We have a client who has instructed Reach Local to manage their paid SEO work etc.  RL have created a proxy version of the page at http://example-px.rtrk.co.uk which mirrors the existing site completely. Would I be correct in assuming that this would count as duplicate content and one or both of the sites would be penalized because of this?  And would the addition of a rel=canonical meta-tag on the proxy site assist with this?Many thanks in advance.
Reach Local Proxy Page - Duplicate content?
duplicate content;canonical url
Yes they would be penalized. Yes a canonical meta tag would help. However Reach Local have put a robots.txt file there to stop search engines crawling it.
