What this tile shows
Traffic and sales over the same dates, in one report, which is the whole argument for reading them together.
Squizzie calls this one Sessions. It reads as a single count.
Where the number comes from
Google Analytics. Traffic, sessions and conversions from your GA4 property, read through the Google Integrations hub.
What you need for it to appear
A connected Google Analytics property. Squizzie connects through the Google Integrations hub, so it is one sign-in rather than an API key.
Charting
This one charts as well as tiles, so it can go on a report as a figure, as a graph, or as both.
The fuller picture
This is one figure out of a bigger subject. Google Analytics without the other tab covers it properly.
