How to create S tier winners
To create S tier creatives, it's essential to understand your customer deeply and to analyze existing winning ads to identify effective variables that can be combined into new concepts. This iterative testing approach allows marketers to refine their creatives using insights gained from lower-tier ads.
AI is not the problem, your skillset is
The speaker emphasizes that limitations in utilizing AI stem from individuals' skillsets rather than the capabilities of AI itself. They argue that by effectively communicating and solving problems with AI, anyone can leverage its potential to build innovative solutions.
why you need to remove metadata from AI ads
The speaker argues that removing metadata from AI ads reduces CPM and alleviates concerns about performance issues related to AI. It is quick and easy to implement, making it a practical decision for advertisers.
why your facebook CPMs are so high
High Facebook CPMs are influenced by multiple variables including creatives, landing page design, geographic targeting, and account spend history. The speaker recommends a systematic testing approach to isolate which factor is the primary driver of elevated costs.
the least important part of ecom when getting started
The speaker argues that branding is overemphasized by new e-commerce entrepreneurs and should not be a priority until reaching $300K+ monthly revenue. Instead, early-stage businesses should focus exclusively on finding winning products, converting ads, and profitable funnels.
you are controlled by beliefs you didn’t choose
The speaker argues that beliefs shape who we are and how we interpret reality, and that most people never question their inherited beliefs. He contends that beliefs should be evaluated not on objective truth but on whether they move you toward your goals, making strategic 'delusion' a valid tool for success.
Why Volume Will Always Beat Research in E-Commerce
Research is important for e-commerce success, but there are diminishing returns when spending under $10K/day. The speaker argues that entrepreneurs often use research as procrastination and should prioritize volume and testing over granular avatar research until reaching significant ad spend levels.
Best ai that takes the least hand-holding for copy
The speaker argues that older Claude Sonnet models are superior for generating high-performing direct response copy, claiming newer models like Opus 5 and newer Sonnet versions have been deliberately constrained with built-in content policies that prevent effective copywriting techniques.
why your CPMs are so high
High CPMs in Facebook ads are often caused by aggressive landing page design, overly promotional copy with all caps, and negative sentiment language rather than just creative issues. Testing new landing pages and analyzing copy sentiment are critical to identifying and fixing CPM problems.
your parents taught you how to stay broke
The speaker explains how limiting beliefs about money, inherited from parents in low-income households, perpetuate financial struggle. He argues that developing a wealth mindset requires understanding the four primary ways to make money: starting a business, investing, having a job, or being self-employed.
stop running ads you can't afford
The speaker argues that if you can't afford at least $50/day in ad spend, you should focus on organic content creation instead. Success requires either capital for paid ads or significant time investment in organic content, with both approaches providing data signals to optimize future efforts.
you need to Invest in yourself if you want to grow as a person
The speaker argues that paying for coaching and education from successful people is a worthwhile investment because it allows you to avoid costly mistakes and time-consuming failures they've already experienced. He emphasizes this as a fair value exchange, noting he's personally invested six figures with one mentor alone.
what a real winning creative actually looks like
A winning creative must earn the right to scale by spending at least $500 and maintaining a cost per acquisition (CPA) below the target threshold. True winners demonstrate consistent performance across multiple scaling methods, geographies, and audiences, indicating genuine viability rather than luck.
Why You Need to Detach From Your Results
The speaker argues that attachment to outcomes in new ventures causes emotional distress and counterintuitively pushes success away. By setting low expectations, focusing only on controllable factors like effort and process, and detaching from results, you can both enjoy the journey more and paradoxically improve your chances of success.
run more ads
The speaker argues that successful advertising strategy prioritizes spending volume over metrics like ROAS, claiming that total ad spend is the ultimate indicator of brand success. The philosophy distinguishes between experienced advertisers ('savages') who focus on spending capacity and novices ('noobs') who obsess over profitability metrics.
Take bigger swings
The speaker advocates for making bold, significant changes when testing in marketing and business rather than small incremental tweaks. Big swings involve testing entirely new page structures, funnel architectures, and creative formats rather than minor optimizations like headline changes.
Intentional doom scrolling
To become a better advertiser, create burner social media accounts and intentionally doomscroll through content your target customers follow, focusing on organic posts rather than ads. When you notice organic content appearing repeatedly (at least three times), that signals it's worth testing as paid advertising creative.
Ai made your ads worthless
AI-generated creatives have become commoditized due to their accessibility and infinite availability, eliminating AI as a competitive moat. The real competitive advantage now lies in the strategic thinking and philosophy behind creatives, with quality and deep understanding of why ads work being the primary differentiators.
Your funnel is a creative multiplier
A funnel acts as a creative multiplier that can dramatically improve the performance of the same creatives. By upgrading your funnel's conversion rate, average order value, or LTV, creatives that previously underperformed can become winners, making it easier to discover high-performing creative without necessarily creating better ads.
Don't split test the first page
Facebook penalizes split testing on landing pages after ad approval because it views post-approval changes as potential cloaking or non-compliance. The speaker demonstrates this through a failed listicle test that only succeeded when retested using new post IDs instead of modifying the original approved landing page.
