Using your audiences in Microsoft Ads
Sync a ContactLevel audience to Microsoft Ads and it shows up there as a custom audience named after your ContactLevel audience. You then add it to your campaign's audience targeting like any other audience list.
Connect Microsoft Ads
Go to Integrations → Connections.
Open Microsoft Audiences (row menu → View details).
Click the connect button, log into your Microsoft Advertising account and approve access.
Select the ad account ContactLevel should sync audiences to.
The status changes to Healthy once the connection works.
Sync your audience
Open your audience and click Syncs.
Click Run next to Microsoft Ads.
The status changes to Synced. The Est. match rate updates after Microsoft processes the audience, so it can show 0% or "Not available" at first.
Use the audience in a campaign
In Microsoft Ads, open the campaign or ad group's audience targeting and add the custom audience with the same name as your ContactLevel audience. Check Microsoft's own minimum size for custom audiences before you expect it to serve.
When you add contacts in ContactLevel, open Syncs and click Run again. The audience updates in place in Microsoft Ads.
Track visits
Add your audience's cl_audience parameter to the ad's landing page URL to see which audience members visit your site. See Finding your audience's UTM parameter.
