I am building a new website for a company. They already have a domain, on which their old website is hosted, but have asked me to purchase a slightly different domain name as well.
I'm just wondering which domain it would be best to build on and which to do a 301 redirect on.
I presume it would be best to build it on the old domain and redirect the new one, but the thing is, this would take much longer and involve much more negotiating with their old web designers.
It would be much faster for me to buy the new domain, do a fresh Wordpress install and build the site, and ask the old web designers to redirect the other domain.
Would it be very harmful to their search engine results? Or would it be a small sacrifice which would allow me to build the new site much more efficiently?
Let me know your thoughts.
