Lookalike audiences

Lookalike audiences allow advertisers to find more people similar to their existing customers. A lookalike audience uses an existing custom audience segment as a “seed” and expands that seed using Yahoo data.

   Data passed

              {
                  "advertiserId": 947366,
                  "name": "subscribers expanded",
                  "description": "subscribers expanded”,
                  "type": "LOOKALIKE",
                  "seedAudienceId": 20064660
              }



      Example response

      {
          "errors": null,
          "timestamp": "2015-07-01 22:03:06",
          "response": {
              “id”: 20136783
              "advertiserId": 947366,
              "name": "subscribers expanded",
              "description": "subscribers expanded",
              "type": "LOOKALIKE",
              "seedAudienceId": 20064660,
              "status": "ACTIVE"
          }
      }

Note that your lookalike audience will be available for targeting immediately, but it may take up to 6 hours for the audience to finish populating with all the relevant users. You should expect limited delivery if you target this segment during this time window.

Target a campaign to a My Audience segment

Once you have created custom audience segments, you can target Yahoo Gemini campaigns and ad groups to serve to these audiences using the TargetingAttribute service, passing in the audience id in the value field.

For example:

POST https://api.gemini.yahoo.com/v3/rest/targetingattribute
