I LAUNCHED A FAKE DEODORANT BRAND TO SEE IF AI WOULD NOTICE

Summary from the TLDR Founders newsletter

Someone spent $11.25 and less than an hour making up a deodorant brand. Three weeks later, ChatGPT started mentioning it. By day 30, the fake brand ranked first in four answers and once beat MAGS Skin, a real product with clinical testing and a National Eczema Association seal. No fake reviews, Reddit posts, or press. It did not take over deodorant search. It worked for only two narrow questions about sensitive skin. Claude, Gemini, and 13 broader searches ignored it. Native still won 99 of 180 answers. The fake brand found two questions the real brands had left open.
