Thanks a lot!Can you please send me via direct message your link to your shop ?
Also another thing ,a lot of people like quotes T-shirt but honestly I don't !But you are right (I think i must make T-shirt more designs for the public )! I really like multicolor layer stencils to make and honestly one of the design was super in social media but nobody have buy it...
While I'm pretty free on here about sharing advice and knowledge, I do not share my designs
Most of my designs incorporate both text and graphics. But either way, Search is text based, so you need to be able to relate your design to some keyword search someone is likely to do. Something like "Ugly Christmas Sweater," "I Love My Pug," "Impeach Trump," whatever. More abstract ideas, or just pretty art, would be much harder to get traffic to.
You don't have to have the design that 95% of people want. If you did have such a design, Walmart and a 100 other people would be selling more of them than you within a month.
But you do need to strike a chord with at least some niche of people. Something they care about, are interested in, love, hate, want to proclaim on their chest. People search for these things, they are their passions. Many such things are bought as gifts, another cat shirt for cat-loving Aunt Martha.
My current best selling designs grew from a couple of shirts I did for a relatively small niche, which was pretty different from the general vibe of my brand. I recently spun it off as its own brand as it was outselling everything else combined--and is far enough out of the mainstream of society that mixing them with my other designs was probably hurting the sales of both. Anyway, for that little niche, I seem to be the only one doing what I am doing for them. Yes, there are other shirts out there for the niche, but they largely seem to be from people with little understanding or insight of the niche and no idea at all of how to mix humor with it.
As to colors ... my earliest best seller was 3 colors. After that it was a 2 colors. Current best sellers are all single color. In general, simple works best for a T-shirt. And black shirts; almost everyone wants black. But do what you do, as we all have our own thing to contribute.
