I have a Shopify where I sell my books, and I've been using Facebook to advertise them.

So far, I have only been advertising one series. It's a romcom. I want to begin creating ads for my other series. However, they are all different genres. Two are cultivation/progression, another is a sci-fi, and one is standard epic fantasy.

While some of the readership will likely overlap, I am worried that using only one pixel to track all of this will make it hard for Meta to create an accurate audience to advertise my books to. I have tried creating a second pixel using Tagfly, but my sales tanked shortly after that so I removed it.

Do I need to create a second pixel? If so, how would I do that without my sales taking a nosedive?
