Segment export: Google Analytics 4, Google Ads, Google Ad Manager and more


To export to Google Analytics 4, Google Ads, Google Ad Manager, or Google Marketing Platform, you need to have Google Analytics 4 destination set by your administrator.

After segmenting the audience, go to the Exports section, where you should be able to find to which destination is currently possible to export the segment (It is possible to set more exports, but it requires the help of the Meiro team).

Export to Google Analytics 4 and share the audience with Google Ads, Google Ad Manager, and Google Marketing Platform.

Exports setting in Meiro

1. Exportable

Exportable shows how many customer profiles will be exported to your destination.

This number is defined by the conditions you choose to segment the audience but also by mandatory attributes that have been set up by the administrator (that must be present to export to your destination).

For example, if you segment 1000 profiles, but only 10 have mandatory attributes present, only those ten will be exported to your destination.

Mandatory attributes are visible in the Data Library/ Destinations tab.

For Google exports, that would be: Google Client ID.

Google Client ID (external_id_ga cookie) should be set together with implementing Meiro Events SDK on the website.  It could be set as an attribute by an analyst that is setting up Meiro or set as a mandatory export attribute for the export. The best practice can be decided together with the Meiro administrator. 

Remember: make sure you use the Google Client ID collected for GA4, which can be found in the Headers part of the event collected or in the dev tools. It is important to note that the Google Client ID for GA4 differs from the Google Client ID collected for UA.

Exported customer profiles need to have a Google Client ID that enables matching between Meiro and Google. 


2. Parameters

Audience Name (required)

Choose Audience Name. It will be visible in Google Analytics 4.

Export your segment manually by clicking on the Export button or set up a schedule (optional), so your export will run at scheduled times.


Remember: ​​GA4 has no separate setting for bot filtering as in UA. Instead, GA4 requires a secret API key to send messages, ensuring that only authorized processes can send messages. As a result, you will see the exported audience in your main view with no additional action needed.

Follow the steps to export to Google Analytics 4, Google Ads environment

After creating a segment with Google Client ID as an attribute and inserting Audience Name in the export's parameters, follow the steps below. 


Google Analytics 4: Find your exported audience under the Realtime / Event section

All audiences will appear as meiro_segment under Reports > Realtime > Event count by Event name.


Warning: If you do not see your parameter within Google Analytics 4, contact the Meiro team.

Warning: The number of Events WILL NOT be equal to exportable customer profiles in Meiro Business Explorer. It is because "events" are not unique customer profiles as in Meiro Business Explorer.

Remember: Uncheck the “Mark as conversion” button under Configure > Events for meiro_segment events

Remember: the visibility of events in GA4 depends on the view settings. If meiro_segment events are not visible, it may be because the view is filtered to exclude those events.


4. Google Analytics 4: Create a new audience in Google Analytics 4 to keep updating it from Meiro Business Explorer

Go to Configure > Audiences > New audience > Create a custom audience

Select Events > meiro_segment


Add parameter > Other > audience name contains the CDP audience segment name





Warning: Google Analytics 4 has a hard limit of 100 audiences, archive audiences when not needed.

Warning: When you create a new audience, it can take 24-48 hours for the audience to accumulate users.

5. Google Analytics 4: Name your audience

Add in the audience name and description if needed. 

For example, in the screenshot below, the name is saved as "All website visitors with Google client ID". 


6. Google Analytics 4: Export your audience to Google Ads

Go to settings > Google Ads links > Link your Google Ads account 

Remember: Export from Meiro to Google Analytics 4 happens in real-time. The audience size in Google Analytics 4 & Google Ads take between 24-48 hours to accumulate users.

 7. Google Ads: Create a remarketing campaign  

Directly from Google Analytics create remarketing ads or log into Google Ads.

Ensure you have enabled the personalized advertising when you linked the Google Ads account


Remember: To target your customer audience, you can create display ads only.

To find your audience, you may need to insert its name in the search box.

While your audience is synchronizing, you can prepare your creatives and text.

8. View results


To check your remarketing ads, create a segment based on your UTM parameters. In the example below the UTM Campaign is google_id_test.

While reviewing the results, it's crucial to address the issue of exported data influencing reported visits in Google Analytics 4. It is recommended to set up a global filter to remove the "meiro_segment" events from the default "audience" labeled as "all users." This eliminates the need to set up the filter separately for each view and report, so the exported data will be excluded from the reported visits.

Learn more: about how to filter out data.

Remember: Please keep in mind that your database attributes can be named slightly differently (as naming is customized for each client). Therefore if in doubt, please contact the Meiro team for details. 


Look at your customer profiles to learn more about the results of your campaign.

For example, here you can see that the last campaign was sent on 07.08.2020 to this customer, and this as well that the customer re-visited the website (after days of being inactive):


This will be visible also within the attribute for that customer profile, together with other available attributes for that particular customer.



Audience duration

It is not possible to remove people from the audience. Once the audience is sent, it stays there.

Remember: The person is removed from the audience after a specified period. This can be defined while setting up the audience as "Membership duration".  Membership duration can vary from 1 day to 540 days.

If you set the value to 7 days, create a new audience, and send the events of all members, the audience will be active to target for 7 days.

If within these 7 days one sends the event of membership to the audience again, the clock resets and a new 7 days period starts running.

Once an audience is created and until events are sent with the same name from CDP to Measurement Protocol, the load is incremental. 

For example, for an audience with a membership duration of 7 days, today an audience of 10 people was exported, and tomorrow an additional audience of 30 people, so it will be considered as 40 altogether. On the 7th day after the first export, it will have a size of 30 people (as 10 people will not be included anymore, their membership was defined for 7 days), but a day after will reset to  0 again (as membership expires for all the audience).

Available destinations through Google

Through Google Analytics 4, it is possible to export to Google Ads Manager as well as other Google services.

List of Google destinations where the custom audience can be exported: 

  • Google search and display advertising (Google Ads Display, Google Ads RLSA, Display & Video 360, Google Ad Manager)
  • Services like Google Optimize

Learn more: from Google documentation here.

Can I export an audience directly to Google Ads?

However, do take note that Customer Match is not available for all Google Ads advertisers. To use Customer Match for Google Ads, your Google Ads account must have:

  • A good history of policy compliance with Google Ads
  • A good payment history in Google Ads
  • At least 90 days history in Google Ads
  • More than USD 50,000 total lifetime spend in Google Ads

If Customer Match is available for your Google Ads account, you also need to have edit rights for your Google Ads account to implement this integration.

Learn more: about the requirements here. 

Can I export to the same Universal Analytics audience on Google Ads using Google Analytics 4?

You will need to manually recreate the audiences in your Google Analytics 4 property as per the settings in your Universal Analytics property. Google Ads will then deduplicate users who are in both the Universal Analytics and Google Analytics 4 audiences.

Does it work in real-time?

Export from Meiro to Google Analytics happens in real-time. 

Export from Google Analytics 4 to Google Ads takes between 24-48 hours.

How to set up Google Ads?

Google Ads are managed through a Google Analytics 4 account, they do not have to be set within Meiro Business Explorer.

Learn more: about how to send the audience to  Google Ads, please go to this article.


There is no limit on how fast and how many events one can send to this API.

There is a limit on how many events will be processed for an account. For example, for Google Analytics it is 10M events per month.  

Learn more: about limitations in the Google documentation.

The number of exported events in Google Analytics is different to the number I see in the 'Exportable" section in Meiro Business Explorer

"Exportable" number in Meiro Business Explorer refers to a unique customer profile (stitched by Meiro's unique identity resolution algorithm) that will be exported to the destination.

At the same time, they are not counted in the same way as "events" in Google Analytics.

Therefore "exportable" and "events" numbers WILL BE different and likely not match.

You can visit the Engagement-Events tab to verify if all audience have been successfully exported.

What information will be exported (mandatory, exported attributes)?

In order to export to Google Analytics 4 destination- the value for attribute "GA ID" needs to be known. This is both mandatory (need to export) and exported attributes (the one that is exported).

The event for each member of the segment will be sent to the so-called Measurement Protocol.

Measurement Protocol is an API with no authentication that accepts all events collected by Meiro Events SDKs of Google Analytics (meaning all page views, transactions, etc.).

Why is the export counted as an event on Google Analytics 4?  

Exporting the audience to Google Analytics 4 will result in an event being sent to your property, therefore it will be seen as an event like any other event being fired.  

You can select the condition to exclude all events from meiro_segment so it does not affect your reporting. 


Why does the audience list size in Google Analytics and Google Ads not match?

It is not advisable to compare the audience list size in Google Analytics and Google Ads because each system has different cookies/identifiers. If there is a low match rate between the two platforms, Google is unable to improve the match rate because of the different cookies, policies and system set-up. 

In Google Analytics, the audience list size can be identified under the Audience Definitions section. 

For Google Ads, the list size is across different networks (Search/Display/YouTube) in Audience Manager. However, these numbers are not expected to be an exact match.

  • Advertising cookies are required for remarketing. Not all of the unique users included in the Analytics estimate will have the cookies necessary to include them in the Google Ads remarketing list. Since the remarketing feature uses both first- and third-party cookies, users who do not have both of these cookies will not be included in your remarketing list.
  • Make sure you've enabled data collection for Remarketing. You can enable data collection in Analytics Admin or by modifying the tracking code for your site or app. You can read more about it here.

Can I export to the same audience on Google Ads using Google Analytics 4?

To use the audience from Universal A, it is necessary to manually recreate the same custom dimension in the Google Analytics 4 property. 

If you need to add an audience to Google Ads, you'll first need to link your Google Ads account to Google Analytics 4 and enable personalized advertising. Only then will you see the audience in the shared library in Google Ads

In the second step, add Google Analytics 4 audiences to your campaign or ad campaigns.

  • Go to the campaign or ad group where you deployed Universal Analytics audiences.
  • Open the Audiences section.
  • Add the Google Analytics 4 audiences to the targeting options in addition to the Universal Analytics audiences.
