The Pennock Knockdown EP 45 Jeremy Yang Founder of Digital Goliath
In this episode of The Pennock Knockdown, Nikki sits down with Jeremy Yang, Founder of Digital Goliath (digitalgoliath.com.au), to discuss the high-stakes world of paid advertising. Jeremy shares his incredible "non-traditional" journey from being a high-school dropout and tradesman to becoming a performance marketing powerhouse.
Together, they dive deep into the mechanics of Google Ads, the evolution of Meta (Facebook/Instagram), and why e-commerce brands must look beyond vanity metrics like ROAS to understand their true contribution margins and inventory health.
Jeremy’s background isn't your typical Ivy League-to-Agency path. After twelve years working as a "tradie" in Australia, he realized his income had a hard ceiling. His transition into marketing was fueled by a desire for results that were both measurable and immediate. "If you want results fast, you have to get into paid media," he was told—and he hasn't looked back since.
In the episode, Jeremy and Nikki discuss how the agency landscape has shifted since 2019. It’s no longer just about "button clicking" in the Facebook Ads Manager. Today’s successful agencies act as holistic partners, helping with creative ideation, UGC scripting, and deep financial analysis. Jeremy explains why he focuses on the $500K to $3M revenue bracket—the "sweet spot" where owner-led brands can move fast and see explosive growth when the right paid media levers are pulled.
One of the most tactical segments of the show covers the "ROAS Trap." While many YouTubers promise 8x or 10x returns, Jeremy and Nikki peel back the curtain on what actually matters for long-term survival: Contribution Margin. Jeremy explains that a brand might be profitable at a 1.5x ROAS if they have high repeat purchase rates and strong margins, while another might be failing even at a 4x ROAS. They discuss:
Inventory Cycles: Why running ads for out-of-stock products is a silent killer of brand trust.
Blended Metrics: Using Market Efficiency Ratio (MER) to see the big picture.
The "Health Score": How Pennock and Digital Goliath evaluate if a brand's problem is the ads, the website, or the product itself.
As we move further into 2026, the platforms are changing. Jeremy highlights the "black box" of Google’s Performance Max (P-Max) and how control is finally being handed back to the operators. Meanwhile, Nikki shares insights into the resurgence of Pinterest for Gen Alpha and the surprising success of Reddit ads for sensitive product categories like women’s sexual wellness.
They also tackle the "Andromeda" hype on Meta and why having "more bullets in the chamber" (creative assets) is the only way to stay ahead of algorithm shifts. Jeremy shares a brilliant "value-add" tactic he used for a beauty brand: creating a "Do's and Don'ts" Canva guide for influencers to ensure their UGC actually converts, rather than just being a vanity post.
