I got accepted almost 2 months ago now and only have 4 sales with 23 of 25 designs up. I am a designer and sell shirts on Spreadshirt without issue but mostly get traffic from social media. I however sell in a very small/targeted niche so it's not hard to rank. With Amazon I wanted to try selling shirts with funny cartoons and jokes, which is very different from what I have sold in the past. But Amazon has a more "mainstream" audience so I wanted to try comedy that appeals to a more "mainstream" crowd. My designs for this new brand get plenty of engagement/likes on social media but I am still not seeing sales. I can't find much solid info formatting descriptions so I wanted to know how you guys were doing it. If I wanted to add a list of long-tail keywords would I put it in the bullets points or in the description at the bottom? Is there any limit to how many keywords I can use?
