About estimated conversions
These days, customers are constantly connected. They use many devices to communicate, entertain themselves and shop. For advertisers, it can be challenging to measure conversions that start on one device or browser and end on another. And it can be challenging to see how some ad clicks lead to shop visits or phone call conversions.
AdWords can give you more insight into how your ads influence new conversion types, such as phone calls, shop visits, in-app conversions and conversions that are completed after a customer uses more than one device or browser. You can do this with the Estimated Total Conversions column. This column combines the Conversions column and estimated conversion types, such as cross-device conversions or call conversions from ads shown on tablets and computers.
Bear in mind
Cross-device conversions, a part of estimated total conversions, are tracked only for AdWords ads traffic on google.co.uk and the Google Display Network, including AdMob, at this time. Cross-device estimates aren't compatible with app install ads or with imported goals from Google Analytics or AdWords Conversion Import.
Not every advertiser will have these estimated conversions because of limited data. For instance, we only show data when we are very confident that our cross-device estimates are highly accurate. In some cases, we'll show a "–" when you might have cross-device conversions, but there isn't enough data for us to make an estimate confidently.
Consumers find out about your business across multiple devices and screens, so you'll want to attribute your conversions – online, in-shop visits or over the phone – to the right campaign or ad group.
Here are some of the benefits of using estimated total conversions to make important advertising decisions:
- See how your AdWords campaigns influence your conversions across devices and browsers, in mobile apps, on the phone and in-shop visits.
- Make more informed business decisions about how you bid online.
- Make better decisions about allocating resources between your online and offline budgets more easily.
- Optimise your mobile bids. Just filter your data by device type so that you can compare estimated total conversions for each.
To start using estimated total conversions, you'll need to do the following:
- Use conversion tracking, including website, phone call or in-app conversion tracking as applicable.
- Record enough conversions in your account for us to make cross-device conversion estimates. The exact number varies for different advertisers because of how estimated conversions are calculated.
Once you've met these two requirements, you can find estimated conversions by signing into AdWords, clicking on the campaigns tab and looking for the "Estimated Total Conversions" column.
We're unable to provide cross-device conversion estimates for conversion data imported from Analytics Goals or offline conversions, at this time.
As we improve our technology, we'll be looking into covering more of your traffic. This means cross-device conversion numbers are likely to increase when we include more products.

Cross-device conversions are counted when people click on an ad on one device or browser and then convert on a different one.
Two examples of a cross-device conversion
- Maria's planning a family holiday. In the morning, while waiting for her train to work, she looks up potential destinations on her mobile phone by searching on Google.co.uk. She clicks an ad for "Honolulu hotels" and likes the website that the mobile ad introduces her to. Later that evening, when she's at home on her tablet, Maria returns to that website to book the trip for her family.
- Whilst looking at a website on his work computer, John clicks an image ad for cinema tickets. Later, he decides to see a film and uses his phone to go directly to the mobile app that the ad suggested and makes a purchase.
Example of a cross-browser conversionWhen a browser is launched in an app, it's often considered separate from the general browser on the phone. Similarly, people might use Chrome one day and another brand of browser the next.
Sometimes, a customer's path to a conversion may involve both a mobile app and an Internet browser. When people view an ad in an app and then complete a conversion in their web browser, or when they view an ad in their browser and then complete an in-app conversion, these are counted as conversions between mobile app and web and are included in your estimated total conversions. These conversions can happen on different devices or on the same device.
This type of conversion does not include app installs, only in-app actions, and is only for Display Network ads. Cross-device conversions between mobile app and web (as well as between mobile app and mobile app) are not available in countries in the European Union at the moment.
Examples of conversions between mobile app and web
- Ellen is browsing the web on her home computer and sees an ad for a sale at her favourite shoe store. She clicks on the ad but doesn't buy anything yet. Later, while riding on the bus to work, she opens the store's mobile app and buys a pair of shoes through the app.
- James is using a mobile app when he sees an in-app ad for an estate agent listing. He clicks on the ad, which sends him to a listing in the app. James remembers the estate agent, and later, on his home computer, he goes to the company's website and fills in a contact form.
- Conversions generated by calls from mobile search ads are counted in standard conversions that can be used in Conversion Optimiser.
- Calls placed after viewing ads on tablets and computers are included in the Estimated Total Conversions column.
Google forwarding numbers are currently available in these countries.
Did you know...
Phone calls are an important channel for research and purchasing, with 70% of mobile searchers reporting using click to call functionality to connect with a business directly from the search results. In fact, consumers make more than 40 million calls directly from Google ads every month.
How it works
Cross-device and cross-browser conversions are estimated using aggregate and anonymised data from people who have previously signed in to Google. Based on this aggregated data, we create an anonymous, aggregate estimate of the number of cross-device conversions attributed to AdWords campaigns.
Like all other conversions, cross-device conversions use what's called "last paid click" attribution. This means that the conversions are attributed to the ad that was last clicked before people make a purchase, submit a lead, download an app, place a call or otherwise take a valuable action.
How to use it
You can use estimated conversions to inform your bidding. There are two main ways that advertisers typically use estimated total conversions: by setting desktop bids and by setting mobile bid adjustments.
- Computer bids: you can use estimated total conversions to guide how you set your computer bids. For example, compare the "Cost/Est. Total Conv." to the "Cost/Conversion" that you see now. If the "Cost/Est. Total Conv." is 10% lower, then you can increase your computer bids for those campaigns by about 10% without adjusting your ROI targets.
- Mobile bids: you can use mobile bid adjustments in your campaigns. This lets you change your bid for mobile ads, based on the value that those ads provide. Many advertisers look at the ratio between estimated total conversions coming from mobile versus computer and tablet to get a sense of the right bid adjustment. To get the most out of your mobile advertising, here's a formula that you can use to set your campaign-level mobile bid adjustment:
Mobile bid adjustment = 100 * [(value per mobile ad click/value per desktop and tablet click) -1]
Sorting your data
The Estimated Total Conversions column can help you to understand the relative contribution to total conversions that mobile, desktop and tablet have made across your ads.
To filter your reports by the device on which an ad click happened, follow these steps:
- Sign in to your AdWords account at https://adwords.google.co.uk.
- Click on the Campaigns tab.
- Click on the Segment drop-down button and select Device.
- Call conversions on the Search Network from both desktop and tablet are included in the "Desktop" row (call conversions from tablets can't be reported separately)
- Mobile calls are included in the mobile row
- Cross-device data for call conversions is only available for Search Network campaigns
- The Estimated Total Conversions column can't be segmented by click type
