Search interest tells you how popular a product category was on a given date and is available in product category insights.
Search interest is displayed as a value out of 100, where 100 represents the peak number of searches within that period. This means that a product category may have 80/100 popularity on Monday compared to the rest of the week, but 40/100 on that same day when compared to the rest of the month.
When viewing a product category at the account level, search interest is based on your shipping countries in Merchant Center. If you’re viewing the category details page within a campaign, search interest will be based on the locations of the campaign, or if you selected “All countries and territories”, it will be based on your shipping countries in Merchant Center.
Note: Search interest is only available for periods beginning on or after February 21, 2023 and can extend up to two years into the past. It will not be available for products with no identifiable category. Search interest data is only available for a number of supported countries today: Australia, Brazil, Germany, France, Great Britain, Italy, Japan, Netherlands, Norway, Sweden, Turkey, United States.
