I've been running ads for my branded store on Taboola for a while and I wanted to expand my sales by introducing more products to my brand. So I created a new campaign for my new product under the same Taboola account, as both products are on the same website and have the same conversion goal. However, I noticed that the CPA for my old product campaign doubled and the spend decreased on the day I launched the campaign for the new product. This continued for over a week, so I contacted my manager, who told me it was due to inventory issues. He suggested creating a different website for the new product and running ads in a different Taboola account for the new product. I'm wondering if this is the correct approach or if there's a way to do this under the same account for the same website. By the way, these things are related to Taboola.
