Google Ads device performance reports, explained for clients
A Google Ads device performance report breaks a campaign's results down by the device people were using when they saw or clicked the ad: mobile phone, computer (desktop and laptop), tablet, and connected TV. It answers a question every client eventually asks: "Are my ads actually working on phones, or am I paying for clicks that go nowhere?"
Most clients never open the Google Ads interface. They rely on the report you send. So the device view only helps them if you translate it into plain language, not raw rows. That is the gap this guide closes: what the device segment measures, how to read a mobile vs desktop split, how device bid adjustments show up, and how to present it so a non-marketer gets it in ten seconds.
We built ReportsMate email-first because, after years around agency reporting, the dashboards clients were handed almost never got logged into. A device breakdown that lands in the inbox, already explained, is the one that changes a conversation. Google Ads is also the most-connected advertising platform among agencies using ReportsMate, ahead of Meta Ads, so this is the report clients ask about most.

Key takeaways
- A Google Ads device performance report segments campaign results into mobile, computer, tablet and connected TV so you can see where budget converts and where it leaks.
- The metrics that matter per device are conversions, cost per conversion (CPA) and conversion rate, not clicks or impressions alone.
- Mobile vs desktop PPC results almost always differ: mobile usually wins on volume and cheaper clicks, desktop often wins on conversion rate and average order value.
- Device bid adjustments let you spend more or less on a given device; the report is how you prove an adjustment worked.
- Clients do not need the full device segment table. They need one sentence: which device is efficient, which is not, and what you changed.

What is a Google Ads device performance report? {#what-is-it}
A Google Ads device performance report is a view of your campaign data split by device category. Instead of one blended number for clicks, cost and conversions, you get a row for each device: mobile, computer, tablet, and connected TV.
The point is that a "good" blended result can hide a bad one. A campaign at a $40 CPA overall might be running $22 on desktop and $75 on mobile. The blended number looks fine; half the budget is quietly underperforming. Splitting by device, or device segment in Google Ads language, is how you spot that.
This sits alongside the other Google Ads breakdowns you already report on, like the geographic performance report and the search terms report. Device is usually the fastest to act on, because a bid adjustment can be changed in seconds. For a refresher on the underlying numbers, our guide to Google Ads metrics explained for clients covers each one in plain English.
Where to find the device segment in Google Ads {#where-to-find}
In the Google Ads interface, device data lives in two places. You can open any campaign, ad group or the Campaigns table and add a Segment > Device breakdown, which splits the current table into rows per device. Or you can open the "Devices" tab in the left menu, which shows the same split with bid-adjustment controls attached.
Both pull from the same underlying data, so the numbers match. Google's own Google Ads Help documentation walks through segmenting a table and applying device adjustments if you want the exact click path.
The catch for agencies is repetition. Pulling this segment by hand, for every client, every month, is where reporting time disappears. Connecting the account once through the Google Ads integration means the device breakdown is pulled and refreshed on a schedule instead of copied out of the interface each cycle. That is the difference between a report you dread and one that just arrives.
Which device metrics actually matter to clients {#metrics}
Not every column belongs in a client report. Impressions and clicks tell you about reach; they do not tell a business owner whether their money is working. The device metrics that earn their place are the outcome ones.
| Metric | What it tells the client | Why it matters per device |
|---|---|---|
| Conversions | How many leads or sales came from each device | Volume is meaningless if it does not convert |
| Cost per conversion (CPA) | What one result costs on that device | The clearest signal of efficiency |
| Conversion rate | Share of clicks that convert on that device | Exposes a device that clicks but never buys |
| Cost / spend | Budget going to each device | Shows where the money actually lands |
| Click-through rate (CTR) | Interest by device | Useful context, not a headline number |
Lead with conversions and CPA per device. A client understands "mobile costs us $70 per lead, desktop costs $30" instantly. They do not need CTR to two decimal places. If you want the full definition set to link out to, what is a good conversion rate for Google Ads gives benchmarks you can quote when a client asks "is that number normal?".
Reading mobile vs desktop PPC results {#mobile-vs-desktop}
Mobile vs desktop PPC results almost never look the same, and the pattern is predictable enough to plan around. Mobile usually delivers more clicks at a lower cost per click, because that is where most searches happen. Desktop often delivers a higher conversion rate and, for many businesses, a higher average order value, because bigger or considered purchases still get finished on a larger screen.
That does not make mobile "worse". It makes them different jobs. Mobile frequently starts the journey (a lunchtime search on a phone) that desktop finishes (the purchase that evening on a laptop). Judging mobile only on last-click conversions undersells it, which is why the attribution window you report against matters. A short window flatters desktop; a longer one gives mobile credit for the demand it created.
The practical read for a client is simple. If one device has a materially higher CPA and you have ruled out an attribution quirk, that device is a candidate for a bid adjustment, a better mobile landing page, or both. Present the comparison as a decision, not a data dump. This is the heart of presenting PPC results to clients well: the number is the setup, the recommendation is the point.
How device bid adjustments show up in reporting {#bid-adjustments}
A device bid adjustment tells Google Ads to bid more or less on a specific device. Set mobile to -20% and you are telling the auction you value a mobile click 20% less; set desktop to +15% and you are pushing harder for desktop. It is the main lever the device report exists to inform.
Device bid adjustments reporting is really before-and-after reporting. You spot an inefficient device, apply an adjustment, then use the next report to show the effect: did mobile CPA fall after the -20%, or did conversions just drop with it? Google's Google Ads Help on device bid adjustments explains the mechanics and the campaign types where adjustments still apply, which is worth checking because Smart Bidding and Performance Max handle device signals differently from manual campaigns.
For clients, skip the percentages. "We shifted budget away from mobile because it was costing 2x per lead, and CPA is down since" is the whole story. Record what you changed and when, so the next report has a clear reference point. A visible change log turns a bid tweak into evidence of active management, which is exactly what retains a client.
How to present device performance to clients {#present}
The best device report is the one a client actually reads, and that is rarely a login-required dashboard. The winning format is a short, branded email: the headline number, the device split, one recommendation, delivered on a schedule. The device table can sit below the fold for the clients who want detail; the sentence at the top does the work for everyone else.
This is where email-first delivery earns its keep. Competitors like AgencyAnalytics, DashThis, Whatagraph, Swydo and Looker Studio build capable dashboards, but a dashboard only helps the client who logs in, and most never do. A white-labelled email, sent from the agency's own domain and sender identity, arrives looking like your work, not a tool's. Keep a steady reporting cadence (weekly or monthly) so device trends are visible over time rather than as a one-off snapshot. See how it works for the setup.
One rule holds across every client: report the decision, not the dashboard. Device data is only valuable once it becomes "here is what we changed and why". That framing is what turns a routine report into proof you are steering the account.
FAQs {#faqs}
Q: What is a Google Ads device performance report?
A: It is a breakdown of your Google Ads results by the device someone used: mobile, computer, tablet or connected TV. Instead of one blended figure for clicks, cost and conversions, you get a row per device, so you can see where budget converts efficiently and where it leaks. It is the fastest of the Google Ads breakdowns to act on, because you can respond to it with a device bid adjustment in seconds. Most agencies report it monthly alongside the geographic and search terms reports. If you want the plain-English version of each metric inside it, our Google Ads metrics guide covers them one by one.
Q: Why do mobile and desktop results differ so much?
A: Mobile and desktop do different jobs in the buying journey. Mobile usually delivers more clicks at a lower cost per click because that is where most searches start, while desktop often converts at a higher rate and higher order value because considered purchases get finished on a bigger screen. A phone search at lunch and a laptop purchase that night can be the same person. That is why the attribution window you report against matters: a short, last-click window flatters desktop and undersells the demand mobile created. Read both devices as a pair, not a contest.
Q: What is a device bid adjustment and how do I report on it?
A: A device bid adjustment tells Google Ads to bid more or less on a given device, for example -20% on mobile or +15% on desktop. You report on it as a before-and-after: apply the adjustment, then use the next report to show whether the target device's CPA improved. Note that Smart Bidding and Performance Max weigh device signals automatically, so manual adjustments do not always apply. Record the date and the reason for every change so each report has a clear reference point, and skip the raw percentages when talking to clients.
Q: Which device metrics should I actually show a client?
A: Lead with conversions and cost per conversion (CPA) for each device, then conversion rate. These answer the only question a business owner has: is my money working on this device? Clicks, impressions and CTR are useful context but should not be the headline. A client understands "mobile leads cost us $70, desktop leads cost $30" instantly and can make a decision from it. Keep the full segment table as optional detail below the summary, not as the first thing they see.
Q: How often should I send a device performance report?
A: Match the cadence to the account's spend and pace of change. Most agencies report device performance monthly, with weekly summaries for higher-spend accounts where a bad device split burns budget quickly. The key is consistency: device trends only mean something across a run of reports, so an automated schedule beats an ad-hoc pull. Google Ads is the most-connected platform among agencies using ReportsMate, so it is usually the account clients most want a steady rhythm on.
Q: Do I need a separate tool to report device performance?
A: No, you can pull it by hand from the Google Ads Devices tab or a Segment > Device view. The reason agencies automate it is repetition: doing that pull for every client, every cycle, is where reporting hours vanish. Connecting the account once means the device breakdown refreshes on a schedule and goes out as a branded email, so you are reviewing the data and writing the recommendation instead of copying rows out of the interface.
Turn device data into a client decision
A Google Ads device performance report is only worth sending if it ends in a decision: which device is efficient, which is not, and what you changed. Get the mobile vs desktop split right, tie every bid adjustment to a before-and-after, and lead with CPA per device instead of a wall of columns. Do that consistently and the report stops being a chore and starts being proof you are managing the account.
