Why Your Amazon PPC Team Needs Access to Your Stock Data

<p>Five years ago you could hire a PPC manager for bids, budgets, keywords, campaign types and structure, and that was the whole job. Today Mike argues that a good Amazon PPC marketer is just a good Amazon marketer, and the job now reaches into what used to be somebody else's problem entirely: fees, refunds, logistics, and the one he thinks is most underrated, stock.</p><p>This is the case for letting your marketing team into your inventory data, and it starts with a client who flatly did not believe it mattered. Conversion rate is a product page problem and a PPC problem, they said. So Olena on the Ad Badger team built the chart that settled it - unit session percentage plotted against warehouse balance - and the split was uncomfortable. Above one threshold the numbers held. Below it they didn't. Sales, conversion rate, Buy Box. Not out of stock. Just low.</p><p>That sent Mike into inventory distortion - the combined financial drain of overstocking and stocking out, estimated to cost global retail 10 to 30% of total sales volume, and almost never mentioned alongside ACoS. He breaks the damage into four buckets: lost revenue that doesn't happen evenly (half a million Buy Box checks found roughly one in three products has at least one location with a suppressed Buy Box), rank decay, the PPC tax you pay while competitors take cheaper clicks, and capital locked up in overstock.</p><p>Then the SOP. Three reports - advertised products, FBA inventory health, and detailed page sales and traffic by ASIN - dropped into Claude with a prompt, and you have a dashboard. Mike walks an anonymized $400K a month account where roughly 30% of the catalog was fully out of stock and a couple of SKUs sat on over 1,000 days of supply. Plus the one nobody automates: nothing tells you when a product comes back in stock, which is exactly when you want the ads switched back on.</p><p>We'll see you in The PPC Den!</p><p><br /></p><p><strong>🦡 Highlights</strong></p><p><br /></p><ul><li>00:00 - Intro</li><li>00:22 - What PPC management looked like five years ago</li><li>01:13 - Fees, refunds, logistics and stock: the new scope</li><li>01:44 - Lost revenue, rank decay, PPC tax and capital lockup</li><li>02:29 - The client who didn't believe it</li><li>03:07 - Unit session percentage vs warehouse balance</li><li>04:22 - Inventory distortion, and the 10 to 30%</li><li>05:36 - Problem 1: lost revenue, zip code by zip code</li><li>05:57 - What half a million Buy Box checks revealed</li><l
