Ad Study

Test your ads and choose the strategy that is driving the most conversions. For example, create a split test to find out which ad set performs the best:

curl \
-F 'name="new study"' \
-F 'description="test creative"' \
-F 'start_time=1435622400' \
-F 'end_time=1436918400' \
-F 'type=SPLIT_TEST' \
-F 'cells=[{name:"Group A",treatment_percentage:50,adsets:[<AD_SET_ID>]},{name:"Group B",treatment_percentage:50,adsets:[<AD_SET_ID>]}]' \
-F 'access_token=<ACCESS_TOKEN>' \

Use ad study for these experiments:

Study Type Use Case

Split Testing

Inform near-term optimization decisions. Example: Is Creative A doing better than Creative B?

Conversion Lift

Measure incremental impact of Facebook ads on business outcomes.

Multi-Cell Conversion Lift

Measure incremental impact of different Facebook ads strategies on business outcomes.

Brand Lift Results

Retrieve and analyze your brand lift study results.

See Lift Study for setting up Conversion Lift and Multi-Cell Conversion Lift.

A lift study object

Examples

To read the details for a study, make a HTTP GET to:

 https://graph.facebook.com/<API_VERSION>/<AD_STUDY_ID>

To read about the cells in a study:

curl -G \
-d 'fields="name,treatment_percentage,campaigns,adsets,adaccounts"' \
-d 'access_token=<ACCESS_TOKEN>' \
https://graph.facebook.com/<API_VERSION>/<AD_STUDY_ID>/cells

Aggiornamento

To update study fields:

curl \
-F 'name="new name"' \
-F 'end_time=1437004800' \
-F 'access_token=<ACCESS_TOKEN>' \
https://graph.facebook.com/<API_VERSION>/<AD_STUDY_ID>

Add a cell an existing study and change treatment_percentage of all the cells:

curl \
-F 'cells=[{id:<CELL_ID>,treatment_percentage:50},{id:<CELL_ID>,treatment_percentage:10},{name:"Group C",treatment_percentage:20,adsets:[<AD_SET_ID>]}]' \
-F 'access_token=<ACCESS_TOKEN>' \
https://graph.facebook.com/<API_VERSION>/<AD_STUDY_ID>

Limitations

To update treatment_percentage for a cell, do it at the study level along with other cells. You also make updates to a study to add additional cells to it. You must provide the percentage of all existing and new cells in the study update since they are correlated.

Once the study runs, you cannot update start_time, treatment_percentage for cells. You cannot remove associated objects such as adsets, adaccounts, campaigns. However, you can update end_time to the future time if the study is not yet ended and add new associated objects to the cells if needed.
