What is Floodlight?

The conversion-tracking backbone under Campaign Manager 360 and the wider Google stack.

Guide · last reviewed February 2026

Floodlight is Google's conversion-tracking framework inside CM360. Floodlight tags fire on your site to record conversions — purchases, sign-ups, page views — and attribute them back to the impressions and clicks CM360 served. It's the connective tissue that lets DV360, SA360, and CM360 share one view of what drove results.

What Floodlight does

Floodlight is how the Google Marketing Platform knows a campaign worked. You place Floodlight tags on key pages of your site — a purchase confirmation, a lead form thank-you, a signup complete — and each time a user reaches one after seeing or clicking an ad, Floodlight records the conversion and ties it back to the media that drove it.

Counter and sales tags

Floodlight comes in two broad flavors. Counter tags count how many times an action happens — sign-ups, page views, downloads. Sales tags capture transactions with values and quantities, for revenue and ROAS reporting. Together they let you measure both simple conversions and full purchase value.

Why it ties the stack together

Floodlight lives in CM360, but its data is shared across the platform. DV360 and SA360 can bid toward Floodlight conversions and report against them, which means all three platforms measure success the same way. That shared measurement is a big part of why partners bundle the products — the value compounds when they're connected. See CM360 vs DV360 for how the pieces fit.

Does Floodlight cost extra?

Floodlight is part of CM360, and tracking activity factors into how CM360 bills — tracking-only measurement is typically handled on its own basis within the platform's volume-based pricing. The full picture is on the CM360 pricing page.

Common questions

What's the difference between Floodlight and Google Analytics?

Floodlight is CM360's ad-conversion tracking, built to attribute conversions to specific ad impressions and clicks across the Google Marketing Platform. Google Analytics measures overall site behavior and traffic. They serve different purposes and are often used together.

What are Floodlight tags?

Snippets placed on key pages of your site that fire when a user completes an action, recording the conversion and attributing it to the media that drove it. Counter tags count actions; sales tags capture transaction values.

Does Floodlight cost extra?

Floodlight is part of CM360 rather than a separate product. Tracking activity factors into CM360's volume-based billing; see the CM360 pricing page for how tracking is handled.
