In this video, I’m showing you a t-shirt niche that’s quietly making Etsy sellers an insane amount of money: kids’ AI-generated birthday shirts. I literally walk you through my “under 10 minutes” challenge where I research, design, and launch a brand-new listing in one of Etsy’s top-selling categories. I use Everbee to spy on what’s already working (yes, shops doing $50K+ months), then I use ChatGPT to brainstorm winning birthday themes, and E-Rank to validate high-search, low-competition keywords like “very first birthday.” Then I design a simple, cute, on-trend retro character concept in Kittl/KD AI (because simple definitely sells on Etsy), add personalization (like a name) to boost conversion, and I show you how I increase perceived value with a back print. After that, I upload everything to Printify, keep color options curated (decision paralysis is real), and publish the listing. To make it scalable, I automate high-converting mockups with SimplyListed and share how to raise AOV by creating matching family sets (Mom/Dad/Grandma shirts). Finally, I explain how I turn one-time birthday buyers into repeat customers year after year by building an email list with Everbee Email—fully automated and Etsy-friendly.
