I Ignored Consent Mode.Then Google Cut My Data.
Six months ago I noticed my Google Analytics data looked thin. Sessions were tracked, but conversion data was spotty.
I assumed a tracking bug until I realized I hadn't set up consent mode on any client sites. Google's been quietly shifting how it collects data based on user consent, and if you're not signaling that, you're losing visibility into conversions and behavior that actually matters.
Consent mode tells Google whether a user consented to analytics or marketing cookies. When someone lands on your site without giving consent, you're still sending data, but Google can't use it the same way.
Google's consent mode documentation walks through implementation, and it's not complicated, but it does mean updating your tag setup. The real issue is most small businesses don't know this is happening, so they lose conversion attribution without realizing why.
What I found is that proper consent implementation actually improves data quality. You're not tracking phantom conversions from people who never consented.
You know what you're measuring and why. It takes about an hour to set up right, and it saves you from deciding on incomplete data.
Check whether your Google Analytics tag has consent mode enabled. If not, look at your cookie banner and privacy policy to see what you're actually asking users to consent to, then configure your GA4 tag to respect those choices. Incomplete data drives wrong decisions.
