Please imagine the following scenario:
abc.com → 302 (temporary) redirect to
After 6 months, we no longer use
def.com, so discard the domain and we buy a new domain
We then do a 302 redirect from
abc.com show up back on Google (temporarily, once we delete the 302 redirect)?
And secondly, would this mean
def.com would disappear and
xyz.com would appear instead of it?
