As we all know, copywriting is a active income business. You get a client, write for them and once your project is delivered. You will have to look for a new client to write for again.
I was wondering how can you turn the copywriting business into a residual income business model?
I know, some ways include royalties per mailing. But we aren't Gary Bencivenga. Not all of us can command such pricing.
Please share some residual income model you have or you are using here:
1) Creating copywriting systems for various niches. They will be buying license to use those systems
2) Multivariety testing(split testing)
