People are now constantly connected and switching seamlessly between devices. In fact, more than 38% of our daily media interactions occur on mobile1. This presents advertisers with new opportunities to reach customers anytime, anyplace, on any device. At Google, we want to help you capitalize on these opportunities and develop new strategies for your business to win on mobile.
Mobile bid adjustments in AdWords enhanced campaigns give advertisers the power to optimize bids across devices — all from a single campaign. In today’s post, we’ll help you understand how to calculate a mobile bid adjustment that accounts for the total conversion value your mobile ads drive for your business.
Review your current desktop and mobile performance
Before calculating your mobile bid adjustment, you can run an AdWords report to review your current desktop and mobile performance. While online conversions, app downloads, and calls are easy to track in AdWords, other conversions such as in-store visits may be harder to attribute directly to your ads. For those conversions, you may need to estimate their value. The closer you can estimate the value of these conversions, the more optimized your bid will be on mobile.
Calculate your mobile bid adjustment
The key to optimizing your mobile bid adjustment is to identify the ratio of mobile vs desktop (and tablet) conversion value. This is calculated by dividing your value per click on mobile by your value per click on desktop.
With this information, the retailer calculates the value per click (for mobile and desktop) by dividing the total value (i.e., the total revenue from all conversion types) by the total number of clicks, respectively. In this case, the mobile value per click is $1.09 and the desktop value per click is $1.21.
The retailer’s mobile bid adjustment is the ratio of these two values: she divides the value per click on mobile by the value per click on desktop and then subtracts 1. In this case we have (1.09/1.21) - 1, or a -10% mobile bid adjustment that can be entered into AdWords.
Iterate and test
As with all online marketing techniques, mobile bid adjustments aren’t something you should just “set and forget.” Frequent iteration and testing will help you account for changes in seasonality or business operations. Due to varying screen sizes on mobile, we also recommend that you keep a close eye on your mobile impression share so that your ads show in the top positions.
