SEO gurus, what do you think the effect of a 301 redirect from an old site (about 5 years old) to a site that is about a few weeks old will be from search engine optimisation viewpoint?
Why would you do that when you can develop the old domain and redirect permanently in-domain ?
It is much more easier to get results like this, than to redirect as you exampled above.
I have done some 301 redirects in the past and theoretically the new domain should substitute the old one at every search result page after Google receive the correct 301 response. Although many people says that domain name does play only indirect role in the seo game -helps only if the domain is used as anchor text- I experienced immediatly huge improvement when redirected my site to a new keyword rich subdomain my older site. (i did nothing which may cause that ranking jump).
