The website oldtimemusic.com was bought on Flippa for $856 and content was published on it.
A 301 redirect was set up from beatcrave.com (bought for $400), which is also in the music niche.
And you can clearly see that the chart had steady growth, and after applying the redirect, it picked up significantly.
These guys clearly know what they are doing.
This is a case where the redirect worked and clearly paid off.
The site gets 86k monthly traffic according to Ahrefs.
