Study first
Review the ideas behind the questions
Review the setup needed for GA4 and Google Ads to share useful advertising data. Check permissions, linked accounts, key-event conversions, and audience sharing. Use those checks when Ads data is missing.
Start with the product link
A Google Ads link is created from the GA4 property. The link is the foundation for Ads data in Analytics and Analytics data in Google Ads.
- A GA4 property can be linked to individual Google Ads accounts or Google Ads manager accounts.
- The Google Ads link is created in Admin under Product Links.
- Creating the link requires sufficient access in both Analytics and Google Ads.
In Practice
Check access before the meeting
If the Ads account does not appear during linking, the first beginner check is whether the user has the required Google Ads access.
Linking is property-level work
A beginner handoff should name the GA4 property being linked, not only the Analytics account name.
Common mistakes
Trying to link Ads from a user who can only view GA4 reports.
Use a user with Editor or Administrator access in GA4 and administrative access in Google Ads.
Q&A
Where does a beginner check Google Ads links in GA4?
Open Admin, then Product Links, then Google Ads links.
Can a manager account be linked?
Yes. GA4 can link to individual Google Ads accounts and manager accounts.
Know what the link enables
The link opens data paths, but some advertising actions still need follow-up work inside Google Ads or Analytics.
- A Google Ads link can let GA4 and Google Ads share data for conversions, Ads performance, and remarketing audiences.
- After linking, Google Ads data can take up to 48 hours to appear in GA4 reports.
- A linked account is required before creating a Google Ads conversion from a GA4 key event.
In Practice
A key event is not automatically a bid conversion
If the team wants bidding in Google Ads, they need a Google Ads conversion based on the Analytics key event.
Audiences need activation steps
Linking makes Analytics data available to Google Ads, but using an audience still requires adding it to a campaign or ad group.
Common mistakes
Expecting a new link to fill GA4 Ads reports immediately.
Allow the documented reporting window and avoid calling missing same-day Ads data a setup failure too early.
Q&A
What extra step is needed for bidding on a GA4 key event?
Create a Google Ads conversion based on that Analytics key event.
Check audience and missing-data blockers
When a linked setup does not behave as expected, the beginner checks are usually the link, sharing settings, account timing, and required data collection settings.
- GA4 audiences can be used in Google Ads as remarketing lists or audience segments.
- Accounts must be linked before key events and audiences can be imported into Google Ads.
- For remarketing, Google Signals or user-provided data collection must be active for the property.
In Practice
Missing Ads data starts with the link
If Google Ads data is missing in GA4, first verify that the property is linked to the Ads account.
Audience sharing can need a few hours
A brand-new link may need time before audiences show in linked Google Ads accounts.
Common mistakes
Assuming a linked Ads account alone proves remarketing audiences are ready.
Check the link, personalized advertising or sharing settings, and required data collection settings before relying on the audience.
Q&A
What is the first check when Ads data is missing in GA4?
Verify that the GA4 property is linked to the Google Ads account.
How can Analytics audiences be used in Google Ads?
They can be used as remarketing lists or audience segments.
