How I Found a Bestselling T-Shirt Design Making $500/Month in Under 30 Days

About this video

Martinez explains how he spotted a Black Cowgirl niche after seeing social-media discussion of Beyonce’s new number-one country song, reasoning that fans would want related t-shirt designs. Researching ‘Black Cowgirl Western Rodeo’ on Amazon, he found AI-style designs of three Black cowgirls whose BSR charts he reads as demand: one made its first sale at the end of January 2024 and had reached about 37K BSR, another uploaded less than 30 days earlier was at about 186K BSR after pricing low at $13.98 then raising price, and a third made its first sale on March 16, 2024. He explains his BSR method - a product only gets a BSR after a sale, and a chart that keeps stepping or nose-diving down signals repeat sales and ranking in the algorithm, potentially several sales a day. He notes the search ‘black cowgirl shirt’ returned about 6,000 results with many mid-page BSRs below 1 million, and suggests variations by state such as Texas, funny phrases, and adjacent phrases like Black Rodeo Queen and ‘Howdy.’ He stresses not copying designs pixel for pixel. In the transcript itself he claims one good design can make $100 to $500 a month, and that some designs have made over $1,000 in a day - presented as his claims, not verified figures.

Key takeaways

  • Watch social-media and music trends outside Amazon for niche ideas, then validate them with Amazon BSR data
  • A falling or nose-diving BSR chart after a recent first sale signals repeat sales and demand in Martinez’s method
  • Do not copy competitor designs pixel for pixel; create an original design once demand is confirmed
  • Expand a validated niche with state variations, funny phrases, and adjacent phrases like Black Rodeo Queen and Howdy
  • Martinez claims in the video that a single strong design can make $100-$500 a month, with some designs making over $1,000 in a day
