ABOUT Malte Landwehr

Malte Landwehr spent more than two decades in search before AI rearranged it. He ran SEO as VP at Idealo, the European price-comparison giant, for five years, and product as VP at Searchmetrics for another five, the kind of in-house and platform career that usually ends in a comfortable senior role. Instead he joined Peec AI as Chief Product Officer and Chief Marketing Officer, convinced that measuring AI search was about to become a category of its own.

Peec AI runs daily prompts across ChatGPT, Perplexity, Gemini, Google AI Overviews, Claude, and Grok and reports what each engine cites. The company says it grew from roughly $500K to $5M in annual recurring revenue during Malte's first six months. His most-cited work there, run with colleague Tom Wells, found that about 83% of the products in ChatGPT's shopping carousel come from Google Shopping's top organic results, a finding he sums up as ChatGPT Shopping being scraped Google Shopping. The study put the claim on solid ground, covering thousands of carousels, tens of thousands of products, and more than a million shopping fan-out queries across ten retail categories.

Malte is a fixture on European search stages, including BrightonSEO and OMR, and writes regularly for Search Engine Journal and his own website at maltelandwehr.de. He is known for a data-first read on Generative Engine Optimization and an unfashionable bluntness about it, including the position that GEO will end up far stronger than SEO ever was. His monthly search-news roundups have made #MonthlyLandwehr a recognizable tag in the field.

227: ChatGPT Shopping Is Scraped Google Shopping with Malte Landwehr, CMO/CPO at Peec AI

Malte Landwehr says the products, prices and ratings in ChatGPT Shopping come from Google Shopping: his team decoded the data and found the top 40 Google Shopping results explain them, with some re-ranking. Malte argues that what Reddit, G2 and news websites say about a brand now matters more than technical SEO, and he calls SEO dead as a default growth channel.
