How do I compare mobile vs. desktop conversions in GA4?
Run a GA4 report with deviceCategory as the dimension and conversions as the metric. It's a fast way to check whether your mobile experience is converting at a materially different rate than desktop.
The report
| Field | GA4 API name(s) |
|---|---|
| Dimensions | deviceCategory |
| Metrics | conversions |
Ask it in plain English
Why it matters
A device converting at a lower rate isn't automatically worth fixing on its own - check its share of sessions alongside it. A device sending 5% of total traffic converting poorly matters far less than one sending 40%, even if the two look equally "broken" by rate alone.

Which GA4 fields does "How do I compare mobile vs. desktop conversions in GA4?" need?
Dimensions: deviceCategory. Metrics: conversions. These are the real Google Analytics Data API field names, so the same report can be built in the GA4 UI, the API, or through Caybl.ai.
Can I just ask "Compare conversions by device category this month." instead of building this report?
Yes. Once Google Analytics is connected through Caybl.ai, ask "Compare conversions by device category this month." and your agent runs the report for you - no need to know the deviceCategory or conversions field names above.
Does asking about deviceCategory change anything in my GA4 property?
No. Running this report doesn't change anything in your GA4 property. Caybl.ai's Analytics scope does allow two narrow write actions elsewhere - marking a key event and linking a Google Ads account - but a report like this one only reads data.
