You’re optimizing the Shopping campaign for an online jewelry retailer promoting its new line of engagement rings. If you know that people who research engagement rings across multiple devices take longer to convert, what should you do to help this client better attribute the impact mobile has on its sales?
Set a short conversion window, such as 7 days
Set a longer conversion window, such as 30 days or 90 days
Create a separate campaign optimized for mobile and compare how it drives sales
Create a separate ad group optimized for mobile and compare how it drives sales
A conversion window is the period of time after a customer clicks your ad during which a conversion, such as a purchase, is recorded in AdWords.
The conversion window setting is ideal for businesses that want more control when measuring their conversions, particularly businesses that sell products with a buying cycle that doesn’t fit the default 30-day conversion window. If you set a longer conversion window, you’ll also be able to see keywords early in the path to a conversion in Attribution reports.
