If your ROAS or MER tanks the moment you push more spend through, this episode is for you.

Carl Weische is the founder of Accelerated Agency and runs CRO for brands like AG1, Huel, Vessi, The Oodie, and 200+ more 8, 9, and 10 figure DTC companies. He joins Andrej on Ecom Growth Insider to break down the exact system he uses to turn CRO into a profit lever from the ad click all the way to the thank-you page.

If your return on ad spend is dropping every time you try to scale, Carl's decision tree is simple:

Fix AOV first.

Fix conversion rate second.

Add presell pages only when you hit a true glass ceiling.

In this episode:

- The 3-tier bundle SOP Carl uses to lift AOV 15 to 25%

- Why revenue per user is the only CRO metric that matters, and the AOV vs conversion rate trap most founders fall into

- When presell and advertorial pages actually pay off (and when they waste ad budget)

- The first things Carl audits on any store before he touches a test

- The four real reasons customers abandon checkout

- How to raise perceived value without killing margin through discounts

- Why AI is about to widen the gap between elite and average marketers

- Realistic testing cadence at scale: 5 to 30+ tests per month

- Carl's sample size rule: 20,000 users and 1,000 orders per variation before you call a winner

- The revenue threshold where it makes sense to move CRO in-house (around $50M to $100M a year)

- Rapid fire: Carl's most underrated CRO lever, most overrated tactic, and the one mistake he sees smart founders make
