Why can I choose only part of my products/collections on the Ad Templates Preview?
The Ad Templates preview presents only a sample of your products/collections. The idea is that the preview will show you how the ads will look like with your actual product, but not necessarily the actual advertised products.
Are the products/collections available in the Ad Template preview, are the ones that AdScale will advertise?
Not necessarily. AdScale algorithms reviews your store data & history and along with similar industry benchmarks form the optimal advertising mix for your store. That means that we advertise the products/collections that have the highest chances of getting the largest number of sales in your current advertising budget. The system might choose to advertise one product, all products or only some, and it changes constantly. The system algorithms will always review and optimize your store advertising mix.
