Google Analytics 4 is one of the independent sources Collabre checks platform numbers against. Social and ad platforms report their own impressions, clicks and conversions, and those numbers are not always right. Collabre pulls sessions and conversions from your GA4 property, compares them with what each platform reports, and shows the difference as divergence. When the gap passes the threshold your team sets, Collabre raises a warning or a critical alert, so a Campaign report is built on numbers you can defend.
The connection also gives you a Google Analytics Hub inside Collabre. The GA4 Properties tab shows realtime active users, pageviews and events, an overview of sessions, users, pageviews and bounce rate, and your top pages, traffic sources and device breakdown. The same hub has tabs for Search Console, Tag Manager, Looker Studio and a Unified Analytics view across every property and site you add. The connection syncs on a schedule, refreshes its own credentials and reports its health.
