Why do analytics or ad numbers drop after I turn on a consent banner?

When you start asking visitors for consent before loading trackers, fewer people may show up in your old reports as “full” visits than before.

What changed

• Before: analytics or ads often ran for everyone, whether they had really agreed or not.
• After: many tools only run in full mode when the visitor accepts (or when the law allows a limited, privacy-safe mode instead).

So a drop in numbers is often expected. It usually means the banner is doing its job: you are measuring people who agreed to be measured (or allowed signals), not everyone who loaded the page.

What you can do

• Compare reports before and after with that change in mind.
• Use consent-aware setups (for example Google Consent Mode for Google tags) so you still get useful, allowed signals when people opt out.
• If something looks broken (zero traffic, tags never firing after Accept), check install order and your tag manager — see Debugging and Site owner checklist.
