Two of my products was hyperponic led grow plants...google what it is. Something like that. But I found out that was a popular niche and I saw it was true from the amount of aliexpress orders(I used the oberlo app)
The third product I used was 3D pens for kids
I used Facebook ads and got traffic but not as much as I thought I would and barely anyone was clicking the ads
I had someone on fiverr design the ads for me and he did a great job so I don’t think the image was the problem...
I don’t know what was the problem
