The Audience Sync syndication is used to keep a segment in sync with a 3rd party platform, including advertising, analytics and engagement platforms. For example, marketers can use this feature to keep any segment in sync with advertising partners like Facebook Custom Audiences, Google Ads Customer Match, and Criteo Ad Platform.

Before setting up the syndication itself, to use the Audience Sync syndication effectively, an advertising platform integration must first be set up. This settings menu can be accessed through the top right settings menu, located here:

  • Click Setup Integrations to access your integration settings.
  • You will see all currently available audience sync integrations. Currently, we support Facebook Custom Audiences, Google Ads Customer Match, and Criteo Ad Platform.
  • Select an integration and click + ADD ADDITIONAL CREDENTIALS to see options that you can use to add an audience on the Blueshift platform.

  1. After the Blueshift authorizes Google integration, click Save.

Criteo Ad Platform integration

  2. On the top right corner, click Syndication + and then click Audience. new_audience_syndication.png
  3. Specify a name for the syndication and click Create Audience Syndication.

The Audience Syndication configuration is organized in three steps: overall configuration, destination configurations and saving / launching.

The Name field is the name of this particular syndication. This is used purely for organization purposes and must be unique for this syndication.

Start Time indicates when this syndication will launch.

Execution schedule is how often this syndication will run and is further elaborated in the following:

Title Purpose
One-time This setting will export the segment on a one-time basis.
Daily This setting will export the segment daily, at the Start Time specified above.
Weekly This setting will export the segment weekly, on the Start Time and 7 days afterwards and so forth.
Continuous This setting will keep the segment in sync with the destination in as real-time as possible. Blueshift will re-evaluate the segment every 5 minutes and update the destination appropriately.


Click on a particular Destination type to add that destination to this syndication. For example, to add a Facebook Custom Audience to sync to, click on Facebook Ads.

Facebook Custom Audience

Sync with Existing


If the Facebook integration is set up correctly, you should see all of your Custom Audiences in the drop down menu. Select the Custom Audience that you desire and double check that the Custom Audience ID matches the appropriate Custom Audience. Please note that Facebook does not enforce uniqueness for Custom Audience names, so there may be some overlapping Custom Audience names.

Create new Custom Audience 

We also offer the ability to create a Custom Audience from our UI. Simply input all of the necessary fields, hit create and save after verifying the Custom Audience ID.


Similarly, selecting Google Ads as syndication destination allows to sync with existing Google user lists or create a new one through exactly the same steps.

4. Launch

After all of the appropriate settings have been filled out, save this syndication and hit launch. This will activate this syndication and users will soon be computed and sent out to all the destinations that you've entered.

For Facebook Custom Audiences, we use Multikey Matching. Instead of just sending Facebook a user's email, telephone number or mobile id, Blueshift uses all available demographical information to Facebook. This allows Facebook to find users who signed up with a different email and/or phone number and significantly increases the overall match rate.

We send the following information, if available, to Facebook:

  1. Email address
  2. Phone number
  3. Gender
  4. Birth Year
  5. Birth Month
  6. Birthday
  7. Last name
  8. First name
  9. First Initial
  10. State
  11. City
  12. Zip code / Postal code
  13. Country code
  14. Mobile advertiser id

For Google, we currently only send over emails, more attributes such as name, country code, and phone number will be supported soon.


5. Monitoring

Click on the previously created syndication in the index page to view appropriate statistics.


The detail view shows the number of users in the segment, the net users that were pushed to Facebook and the total number of Facebook Custom Audience matches.

  1. Note that the size of audiences in either Facebook, Google, or Criteo are reported based on their policy, and usually not in real time.

  2. Stats are updated in real time and will reflect the active state, refreshing the page will refresh the stats.

  3. Stats are stored per day, as per hour stats would not be accurate due to Facebook, Google, or Criteo's delay in adding users to audiences.
