What the best way of getting out of the following problem. I have 2 different domains both with exactly the same content on each. They are both about a year old and it seems that both are not been indexed by any of the search engines. I realise now that the search engines penalise you for this. What is the best steps to take to fix this problem. Will a 301 redirect work? Will it take long for either of the sites to be unbanned? Any help is appreciated. Thanks.
Why you need 2 sites with same contents? In your case I feel 301 is not the solution as it's one year and one can not rule out the possibilities if they are in SE's index. The best option you can try is remove all the pages from one domain and leave it as it is. Update new contents on domain you like to use.
