I have some domains to catch spelling mistakes, for example
http://www.mysupredomain.com
http://www.mysuperrdomain.com
http://www.msuperdomain.com
They all redirect to
http://www.mysuperdomain.com
(This is just an example)
I have noticed that these spelling-error-catching domains are not necessary, and I would like to abdandon these.
However, I think that Google might not like having domains suddenly not being reachable anymore.
Is there a way to tell Google that I will abandon these domains so that I will not get a lower page rank?
