Summary: In episode 201, Kevin King breaks down the AI ads playbook and the rule the episode is named after: AI wins the test, humans win the close. Plus Amazon quietly showing sellers exactly how manual PPC ends, the tariffs coming back from the dead under a brand new legal justification, and Amazon's quietest sixty billion dollar business that most sellers aren't even playing.

Key Points Discussed:

AI video for paid ads is the biggest make-money lever in AI right now, and the one with the loudest hype. Meta's AI-powered ad tools just hit a $10 billion annualized run-rate, growing roughly 3x faster than its ads business overall. RevenueCat ran an AI digital-twin avatar against a real human creator: the avatar hit 87% of the human's conversion rate at $20 per avatar versus $500 per creator, with a 31% lower cost-per-acquisition.
Read that carefully: AI got about 90% of the result at about 4% of the cost. It won on economics, not quality. The only independent academic study (Taboola with Columbia, Harvard, TUM and Carnegie Mellon) found AI ads averaged a 0.76% click-through rate versus 0.65% for human ones. The "45% higher conversion, 3.4 ROAS" stats floating around are anonymous agency blog claims with no named brand, so plan around the modest number.
In trust-dependent categories like finance, health and beauty, real people still convert better at the bottom of the funnel. One first-party $100K test had human UGC winning click-through 2.4% to 1.9%, AI winning on cost-driven ROAS, and the hybrid beating both. The loop: generate wide, test cheap on equal budgets, judge on cost-per-acquisition rather than likes, kill losers fast, scale the top two or three, and log the winning angle rather than just the clip.
Track cost per finished, usable, converting video, not cost per generation. Budget 15 to 25 percent for regenerations. That $1.50 clip everybody brags about is usually a $5 to $8 finished video once you count the misses and the assembly. Still far cheaper than a human shoot, but now you're not lying to yourself.
Interesting stats: only 2.2% of US households currently pay for AI, but the line has climbed almost straight up since the start of 2023. The paid AI habit is compounding fast and nowhere near saturated.
Amazon just showed you how manual PPC ends. A new Targeting strategy beta has landed inside manual Sponsored Products campaigns, and it's one checkbox that's easy to scroll past. Flip it on and Amazon's AI adds up to four new keywords and product targets every 12 to 24 hours, at or below your current bids. It also pauses targets using the exact rules its algorithm applies: no impressions in 3 days, no clicks in 7 days, over 15% of daily budget spent without converting, or 20 or more clicks with no conversion in 14 days.
Why Amazon is doing it: Performance Max already proved automation grows ad revenue faster than any bidding interface, every keyword the AI adds is another auction Amazon monetizes, and every campaign that opts in becomes training data. Opt-in beta, then default, then merged with ROAS bidding, until you simply hand Amazon a budget and a goal.

Software tool of the day: Amazon is cutting every product title to 75 characters, and if the keyword that gets trimmed is the one printing your sales, your ranking goes with it. Tomer Rabinovich's new skill rewrites titles into the 75-character format, keeps the highest-value keywords up front, and writes the new Item Highlights field. A title diet for your listings: same muscle, less fat.
The tariffs are dead, long live the tariffs. As the temporary 10% global tariff under Section 122 hit its 150-day limit on Friday, the US rolled out fresh tariffs on 60 trade partners citing forced labor violations under Section 301. The countries covered account for 99.4% of US imports, with duties from 10% to 12.5%. Two more waves are queued, including a USTR probe into 16 countries and a separate wave targeting the EU, so price your 2027 POs with tariffs baked in.
Amazon's quietest $60 billion business: Marketplace Pulse says Amazon Business just hit $60 billion in annualized gross sales, up from $25B in 2021, closing in on Amazon's $68.6B ad business. More than half comes from third-party sellers, so roughly $30 billion, and most sellers aren't playing. Recent investment all went to buyers while seller-side tools barely changed, and it's growth you don't have to buy at auction. It crosses $100 billion before the end of the decade.

Stump Bezos Answer: $49.2 billion. After US importers received $22 billion in tariff refunds in May, the June figure more than doubled it.
