In this episode of Chew on This, Ron and Ash are joined by Constantine Yurevich, Founder of SegmentStream, to discuss the challenges and future of marketing measurement and attribution. If you care about scaling profitably, avoiding wasted ad spend, and finally getting clarity on what’s actually driving results — this one’s for you.

What You’ll Learn: Why one-size-fits-all attribution models just don’t cut it

We talk about why standard setups miss the mark — and why your measurement approach needs to reflect how you actually sell and market, not someone else’s template.

When attribution becomes a make-or-break issue

If you're spending big, measurement mistakes get expensive. We get into why attribution becomes non-negotiable as budgets grow — and how smaller teams can still start smart.

How to surface conversions that don’t get credit

Some channels drive value you can’t see in your analytics dashboard. We dig into how things like geolocation and session behavior can expose what’s really moving the needle.

Why marginal ROAS tells a more honest story than averages

Looking at average ROAS is easy — but misleading. We unpack why marginal ROAS gives you the real picture, especially when scaling campaigns.

Who you can actually trust when it comes to attribution advice

Spoiler: It’s not always your media agency or the platform reps. We talk about why having someone with no skin in the game is crucial for objective decision-making.

Plus: Real-world stories of brands that got attribution wrong — and what they did to turn things around.
