I’m new to selling tablecloths on Amazon and struggling with my ad structure. Hoping someone can share best practices.

My listing has many size + color variants:

Colors: White, Black, Pink, Blue

Sizes: S, M, L, XL

For single-variant products, I just advertise the best ASIN.

But with variants, my top performer is Blue L. I’ve been advertising using core keywords like “tablecloth L” for a month.

Result:

All L-size variants sell really well, but S, M, XL barely move. Keywords aren’t spreading to other sizes/colors like I expected.

My questions:

  1. Should I create separate campaigns for Blue S, Blue M, Blue XL with keywords like “tablecloth S”, and so on?

  2. Was my whole approach wrong? Should I just use the core term “tablecloth” without size restrictions, add all Blue ASINs, and let the data decide?

How do you structure ads for variant listings to cover all sizes/colors and boost overall sales?

Thanks for any advice.
