Facebook Custom Audiences Get Expanded Matching Capabilities

Facebook has improved the matching capabilities of their Custom Audiences feature. Up until now, the matches could only come from a single attribute (i.e. email, phone number, first name, last name, etc.). With the new update, matches can come based on multiple attributes in order to have a higher match rate with the same level of accuracy as can be found with the single attribute matching. The new feature has been released in the Ads API.
