Bought a domain which is forwarding to the same site, how can I monetize this?

I have buying old blog domains, "reviving" them via archive.org scrapes and monetizing them. Just started, so no results yet.

I didn't do my research and purchased a domain which is forwarding to another domain name for that blog, same exact website. Looks like they changed their domain name a few years back and I did not catch it.

So scraping and re-posting would be a bad idea.

The back-links are relevant and not spammed. What do I do to monetize this? Here are my ideas:

• Auction the domain
• Create a similar website, amazon affiliate focused ( based on the niche )
• Create a niche site and auction it on Flippa
• any ideas?

Pretty new to this so thank you BHW!
