they end up on my store and on my store i have a link to my patron for those looking for subscription services.
you really need to start collecting emails so you can market on the backend...and more importantly you can measure how much money you make from each $100 you spend in ads.
Like...try testing something like...
FB Ad --> Landing Page offering a $5.97 ebook --> after purchase you can offer a upsell (another product that cost more)
The idea is that once someone spends a low dollar amount with you, they will feel comfortable spending more with you later.
or FB Ad --> Landing Page offering free version of a comic you have in exchange for their name and email --> then offer a upsell right away (doesnt hurt to try)...and then email market to them in the future about projects coming up in the future.
Even if they dont purchase the upsell, you have their email where you can market more to them in the future for FREE.
Check out this cats video (his youtube channel is solid as well...he also has courses for around $100 that will teach you everything):
