Visitor segment to report orders after a prior visit

Hi

I am reporting on orders generated via a blog. I can easily report on orders during a single visit, but I want to also report on orders placed up-to 12 weeks after the blog attracted a visitor.

I've created the below segment for use in an Analytics Workspace:

Segment Type: Visitor

Entry Page is a blog page,

Then within 12 weeks,

Visit Container [Orders is >= 1]

I've not much experience working with Visitor segments, so wanted to sense check what I've done with more experienced users and/or check if there's a more efficient way to do do this.

Thanks in advance.
