Cross Device Attribution Reports in Google Ads (AdWords)

 

 
By using cross device attribution reports in Google Ads (formerly Google AdWords) you can determine:

#1 How your customers who interacted with your search network ads (somewhere in their shopping journey) used different devices to convert on your website

#2 What role these devices played in their conversion paths.

For example, there is a possibility that some devices (Mobile, Tablet, Desktop) could be assisting conversions rather than directly completing conversions on your website.

This is generally the case with high priced items such as jewellery.

Often people do not feel comfortable carrying out high value transactions (like purchasing Jewellery) on mobile devices.

They may use their mobile devices for Jewellery research and then may return to your website later via desktop, to complete their purchase.

So if you are advertising on mobile devices and people are clicking on your jewellery ads but not making a purchase then it does not always mean that your mobile ads are not working.

It could be that people are using their mobile devices just for researching about your product and then later returning to your website directly, via desktop computer, to complete their purchase.

Through ‘cross device activity’ reports in Google ads, you can measure such cross device behavior of your website users.

Without the insight from cross device reports, you may never understand the role your mobile ads played in the conversion path.

You may then label your mobile ads ineffective and may even stop bidding on them.

If you are getting cross device conversions in Google Ads then you can benefit from cross device activity reports.

Note: Cross device conversions are recorded for ads on Google Search Network, Google Display Network and YouTube. They are not recorded for: mobile app install conversion actions, goals imported from Google Analytics, goals imported via Google Ads Conversion Import.

  • Last Click Conversions
  • Last Click Conversion Value
  • Click-Assisted Conversions
  • Click-Assisted Conversion Value

The ‘Assisting Devices’ report also report on following three metrics:

  1. Mobile Assist Ratio
  2. Tablet Assist Ratio
  3. Desktop Assist Ratio

Mobile Assist Ratio

This metric tells you how often your mobile ads assisted conversions that were completed on other devices.

For example, a mobile assist ratio of 2 means that for every conversion completed on a mobile device, 2 conversions on other devices were assisted by a mobile device.

Google ads calculate and report on the ‘mobile assist ratio’ based on ad clicks and ad impressions.

Mobile Assist Ratio (based on ad clicks) = Click-Assisted Conversions / Last Click Conversions

Mobile Assist Ratio (based on ad impressions) = Impression-Assisted Conversions / Last Click Conversions

Tablet Assist Ratio

This metric tells you how often your tablet ads (ads on tablet devices) assisted conversions that were completed on other devices.

For example, a tablet assist ratio of 2 means that for every conversion completed on a tablet device, 2 conversions on other devices were assisted by a tablet device.

Google ads calculate and report on the ‘tablet assist ratio’ based on ad clicks and ad impressions.

Tablet Assist Ratio (based on ad clicks) = Click-Assisted Conversions / Last Click Conversions

Tablet Assist Ratio (based on ad impressions) = Impression-Assisted Conversions / Last Click Conversions

Desktop Assist Ratio

This metric tells you how often your desktop ads (ads on desktop devices) assisted conversions that were completed on other devices.

For example, a desktop assist ratio of 2 means that for every conversion completed on a desktop device, 2 conversions on other devices were assisted by a desktop device.

Google ads calculate and report on the ‘desktop assist ratio’ based on ad clicks and ad impressions.

Desktop Assist Ratio (based on ad clicks) = Click-Assisted Conversions / Last Click Conversions

Desktop Assist Ratio (based on ad impressions) = Impression-Assisted Conversions / Last Click Conversions

The ‘Device Paths’ Report

 

device-paths-report

 

device-paths-report2

This report shows the top cross-device conversion paths and allows you to determine the order in which customers used different devices before they converted on your website.

As such, a traditional MMM model is not suitable for carrying out digital marketing mix modelling aka attribution modelling.
