In episode 100 of our weekly Hump Day Hangouts, one participant asked about the SEO value of a 10-year-old parked domain with no content.
The exact question was:
I have a client with about 10 domains that are 10 years old. I've checked the waybackmachine and they were all parked or had errors. None of them ever had related content on them. Is there any SEO use in these domains and if so, what is the best use?
