When I search for the keywords (I am interested in) such as "English online for kids" (curently No. 10 on Google) or "Learn English for kids" (currently No. 16 on Google) or simply the website's name "Mingoville" sometimes I see www.mingoville.com other times www.mingoville.dk, www.de.mingoville.com or worst www.de.mingoville.com/content/view/13/29/lang,fi/ Do search engines see the site as three different ones? Does it have to do with incorrect redirect or what problems do you see? Any ideas from SEO experts? Thanks.
It seems you are using a url rewrite to point all 4 of those domains to this one: http://www.de.mingoville.com/content/view/13/29/lang,en/ (which is obviously delivering the "en" english page for me, and the "fi" page for you). It may be because google spidered your site before you had the url rewrites in place and still has the old domains in it's index, or it may be because you are not using a proper url rewrite rule. How are you redirecting the traffic to the canonical URL?
You have redirected all the domains to a single website...and what you said that you are seeing different pages for the same keywords,it is due to you haven't remove your old indexed pages from google...
