In episode 229 of our weekly Hump Day Hangouts, one participant asked if using expiring domains with keyword-optimized URLs and redirecting them to the Google site is better than using PBNs.
The exact question was:
is it a good idea to find expiring domains with keywords in the URL and natural links going to them, and 301 these to a Google site.
or would it better just to send PBN's to the Google site instead.
assuming the PBN's will probably be more powerful but will probably be random URL's compared to relevant URLs and less power with the expiring domains.
