Welcome to the Q&A Forum

My version 1 url was 301 redirected to version 2, years ago. If the version 1 is no longer contributing any SEO juice I would like to cancel that cancel that domain. Is there a way to know if the version 1 url still has any impact on SEO?

Many years ago I created website www.original.com.  Two years ago I redirected website www.original to www.neworiginal.comusing 301 redirects. I have now created www.rebranded.com. I want to maintain all SEO value. Should I redirect both www.original.comand www.new original.com to www.rebranded.com? Or do I only need to redirect one of them and if only one which one?  If I need only to redirect one can I delete the other, why or why not. Of course the url are fictitious. I truly appreciate your help
