Duplicate Content within Site

[CalicoKitty2000]

I'm very new here... been reading a lot about Panda and duplicate content.  I have a main website and a mobile site (same domain - m.domain.com).  I've copied the same text over to those other web pages.  Is that okay?  Or is that considered duplicate content?

Its not okay. instead of having two sites you should have one site in responsive design, that should take care of duplicate content. https://developers.google.com/webmasters/smartphone-sites/details

If however you require to have a separate mobile site, the content should differ.

It would be best to have a responsive site in terms of SEO and for your own content management issues however if you currently have separate URLs (as you do with the m.domain) then this is useful https://developers.google.com/webmasters/smartphone-sites/details#separateurls and also this post on moz Mobile Site Audit Checklist from March 3rd, 2014 would also be a good read.

Responsive is the way to go in my opinion.

Thank you for your responses!  Looks like I have some work ahead of me.  A short term fix and a long term fix.  My site is somewhat responsive now, but not all the way down to mobile size.  I need to look at taking it further.  Thank you!
