My site has been uploaded to 3 different domains abc.com, pqr.com and xyz.com. The contents, images and the whole domain is totally same. I have checked that abc.com has been cached in google.com. I do not know whether the other 2 sites are in sandbox or not.. How to know that the site is in sandbox or not?? Should I 301 redirect both the domains pqr.com and xyz.com to the abc.com ?? Should I continue to do the SEO for abc.com and remove the site content from other 2 domains?? Can anybody please help me by suggesting the best solution to this problem.
That is the best option, if not, then do care to explain why do you want the same content on 3 sites, rather if you wish to dominate the first 3 spots on SERP using 3 sites then go ahead and do it, but use different content.
I think redirecting is the best option. if three domains have the same contents, all three sites are considered as duplicated contents. it effect seo directly. use 301 redirect to the most appropriate domain and get focused on it.
Indeed - you will be penalized by the search engines if you have duplicate content on multiple domains. ^^This is the best solution.
