Audience Not Appearing in LinkedIn

• Verify sync status in ContactLevel dashboard

• Wait 24–48 hours for processing

• LinkedIn requires minimum 300 matched members

• Try disconnecting and reconnecting LinkedIn in Integrations

Low Match Rates on LinkedIn

Audience Shows as "Too Small"

• Add more contacts (aim for 500–700+ to clear the 300 minimum after matching)

• Improve data quality with LinkedIn URLs and work emails

• Wait for full processing (up to 48 hours)

Sync Failures

• Most common cause: expired access token. Disconnect and reconnect LinkedIn.

• Verify account permissions

• Contact support if issue persists

Ads Not Delivering

• Check audience is in "Ready" status

• Verify bid, budget, and schedule

• Avoid over-narrowing with additional targeting filters on top of your custom audience
