How to Link GA4 and DV360: A Self-Serve Advertiser's Guide

Why Link GA4 and DV360?

If you run a self-serve Display & Video 360 (DV360) seat, connecting it to Google Analytics 4 (GA4) is one of the highest-value integrations you can set up — and one of the most commonly misconfigured. A clean link unlocks three things that materially change how you buy and measure media:

• Audience activation. Build audiences from GA4 behaviour (purchasers, cart abandoners, high-value sessions) and target or suppress them in DV360.
• Conversion import. Bring GA4 conversions into DV360 so you can optimise bidding toward real business outcomes rather than proxy clicks.
• Cross-platform reporting. Reduce blind spots between what GA4 sees on-site and what DV360 reports on media delivery.

This guide walks through the practical setup for a self-serve advertiser, the permissions you'll need, and the mistakes that quietly break the connection.

Before You Start: Prerequisites

Linking isn't just a toggle — it depends on how your accounts are structured. Check the following before you begin.

Account and property requirements

• A GA4 property with data flowing (not a legacy Universal Analytics property).
• A DV360 self-serve advertiser inside a partner you can access.
• Both products ideally sitting within the same Google Marketing Platform (GMP) organisation. Cross-organisation links are possible but add friction.

Permission requirements

The link touches two platforms, so you typically need rights in both.

Platform	Minimum role needed	What it controls
GA4	Editor (or Administrator) on the property	Creating the link, exporting audiences, sharing conversions
DV360	Advertiser-level admin access	Accepting the link and activating audiences/conversions
GMP Organisation	Org admin (for first-time links)	Associating products across the org

If you're missing org-level access, your setup will stall at the handshake stage. This is one of the most common reasons a link appears "pending" indefinitely.

A note on consent and regional rules

Audience and conversion sharing depends on your consent configuration and the regions you operate in. Make sure Consent Mode and your GA4 data collection settings are aligned with your privacy obligations before you push audiences into media activation.

Step-by-Step: Linking GA4 to Your DV360 Advertiser

The link is initiated inside GA4, then confirmed in DV360.

Step 1 — Open the GA4 product links

1. In GA4, go to Admin.
2. Under the property column, find Product Links.
3. Select Display & Video 360 links.
4. Click Link.

Step 2 — Choose your DV360 advertiser

Select the DV360 advertiser you want to connect. If you manage multiple advertisers under a partner, make sure you pick the exact advertiser ID that will run the campaigns — linking the wrong one is a frequent and frustrating error.

Step 3 — Configure link settings

You'll be asked what to enable. The two core options are:

• Enable personalised advertising — allows GA4 audiences to be exported to the DV360 advertiser for targeting and suppression.
• Enable cost data / reporting options — brings DV360 campaign and cost data into GA4 reporting where available.

Enable both unless you have a specific reason not to. Personalised advertising is what makes audience activation work.

Step 4 — Review and submit

Confirm the settings and submit the link. Depending on account structure, the link may be active immediately or require acceptance by a DV360 admin.

Step 5 — Confirm in DV360

In DV360, open the relevant advertiser and check that the GA4 property now appears as a linked data source. Linked GA4 audiences should start to populate in your audience library (allow time for them to build — see below).

Activating GA4 Audiences in DV360

Once linked, any eligible GA4 audience can be exported for use in DV360. A few practical points:

• Audiences must be marked for export or created with advertising personalisation enabled.
• New audiences only start collecting members from the point they're created — they are not retroactive beyond GA4's lookback allowances.
• Expect a population delay. Smaller or very specific audiences can take time to reach a usable size, and some may never meet minimum thresholds for serving.

Smart ways to use GA4 audiences

• Suppression lists. Exclude recent purchasers from prospecting line items to cut wasted spend.
• Sequential retargeting. Target users who viewed key pages but didn't convert.
• Value-based segments. Build audiences around engaged sessions or high-intent events, then layer them into your DV360 targeting.

For teams building a durable first-party data strategy, GA4 audiences are a strong foundation. If you want help designing an audience architecture that scales, our DV360 managed services team does this daily.

Importing GA4 Conversions for Optimisation

Beyond audiences, you can bring GA4 conversion events into DV360 to inform automated bidding.

• In GA4, confirm the events you want are marked as conversions (key events).
• Once the link is active, these conversions become available to select within DV360.
• Choose which conversions feed your bid strategy carefully — optimising toward a noisy or low-volume conversion will produce erratic pacing.

Align your DV360 optimisation goals with the handful of conversions that genuinely represent business value. More conversion signals isn't always better.

Common Pitfalls and How to Avoid Them

Problem	Likely cause	Fix
Link stuck on "pending"	Missing org-level or advertiser admin rights	Confirm GMP org admin accepts the handshake
No audiences appearing	Personalised advertising not enabled	Re-check link settings and audience export flags
Audience too small to serve	Narrow definition or short collection time	Broaden criteria and allow more time to populate
Wrong advertiser linked	Selected incorrect advertiser ID	Remove and re-create the link to the correct ID
Conversions not importable	Events not marked as key events in GA4	Flag the correct events as conversions first

Housekeeping that saves headaches

• Document who owns the link and the permissions behind it.
• Audit linked audiences quarterly and archive segments you no longer use.
• Re-validate the connection after any major account restructure or user offboarding.

Self-Serve vs. Supported Setup

The link itself is straightforward, but getting value out of it — audience design, conversion selection, bid strategy alignment — is where experience matters. If you're running a lean in-house team, a DV360 self-serve account gives you full control while keeping overheads low. If you'd rather have specialists configure and optimise the integration alongside you, a co-managed arrangement blends your control with our platform expertise.

Not sure which model fits your team's maturity? Compare the options across our services and pick the path that matches your resourcing.

Final Checklist

Before you consider the integration complete:

• GA4 property is collecting data and uses Consent Mode appropriately
• Correct DV360 advertiser linked and confirmed in both platforms
• Personalised advertising enabled on the link
• Key audiences created, exported and populating
• The right GA4 conversions imported and mapped to bid strategies
• Ownership and permissions documented

Get these right and you'll have a measurement-and-activation loop that makes every DV360 campaign smarter over time.
