The purchase probability

The purchase probability  is checked for  each keyword how high it is. This means that your shop story checks what Google shows here in the SERP (Search Engine Result Page). So many different metrics are considered here . 

For example, it is checked whether  Google Shopping ads are automatically displayed for a search query with the respective keyword from Google. If this is the case, this is taken into account in the purchase probability and gives the user information about it.

This is subsequently also taken into account for Shopstory's recommendations for placing  Google Ads.
