Changing domain name of the website
 

My website lost rankings in Google after last algorithm updates. I have removed all the bad links from it but still can not see any positive results for the website. Now I am planning to redirect the old domain to the new one. Is it possible to use the same content? Will it cause problems in indexing the new website? Will the content be considered as copied from the original domain? I am going to use keyword in new domain name. Will using keyword be beneficial in new domain? Please let me know if any other option is available besides changing domain name for better SEO results.
