How can I link domain to a specific page?

Where is the domain registered? Most registrars that I'm familiar with offer an option to forward a domain name to a specific URL. So visitors will type in something like www.oldurl.com, and you can have that url forward to www.newurl.com/somepage. Visitors will see that they have been forwarded to your new site, but that's probably ok. You want them to know the new URL anyway.

I've found the web forwarding option and it has worked perfectly. A massive thank you for your help @jonathangennick

Happy I could help! Glad the idea worked.

I am about to do the same thing – integrate a second site onto a page on my main site. Is this where you were able to forward your second domain to a page on your main domain?

Also, both of my domains are Squarespace domains, if that makes any difference.

Does this work to forward it to a specific page, and not just a specific homepage of another domain?  My 2nd domain is not registered with squarespace, so maybe it's only possible with ones registered with squarespace?   I've updated elbpapercutting.com to forward to birdmafia.com/elb/process, but it still just goes to birdmafia.com.  I'm going to wait a few hours to check it again, in case there's just a delay.
