The Subida AI blog: selling digital products with ads you can actually measure

This is where we write about advertising you can put numbers on: where customer acquisition cost comes from, what creative really changes, how to build a funnel that pays for itself, and when to stop scaling. For mobile apps, online courses and other digital products.

There aren't many posts, because we don't publish just to fill a page. You'll find more specifics on the pages about campaigns, pricing and case studies — the links are at the bottom.

Frequently asked questions about this blog

Irregularly. A new post goes up when there's material that can't be summed up in one paragraph on a service page. We don't publish a schedule, because we don't want to keep moving it.

The economics of campaigns for digital products and mobile apps: how to measure return on ad spend, how a web2app quiz funnel works, how many creatives you need to test before a result stops being luck, and where in the funnel conversions most often leak.

On three pages: “Facebook ads for online courses”, with the break-even formula worked out; “How we bill our clients”, covering the retainer and revenue share; and “Case studies”, with four projects described in numbers.

Grzegorz Świerad, founder of Subida AI. The posts are based on projects he ran personally — Mentorist, Neurony Szaleją, Silne Dziecko and “Cisza w świecie dziecka”.

The ideas, experience and examples come from the author — usually from his notes and voice recordings. AI helps with editing: it tidies the structure and smooths the language. It doesn't invent results or stories that never happened.
