- Targeting at the Product ID level is the most granular but depending on how many products you have it can be unscaleable.
- The next best option is to use category combinations. For example: combine the brand target of Fender and the adwords_label you’ve made for acoustic guitars so that you can place a specific bid of Fender acoustic guitars.
- Targeting categories is like bidding on broad match keywords. The more labels you can make the better.
- All Products is your catch-all that should still stay active after any other segments have been created. It can also give you ideas on new categories to make by looking at the search query reports.
