How are you currently testing new audiences on Facebook? If you're looking to rapidly and automatically build new audiences and test these in different ad sets, you're in the right place!

First, login to your account at and navigate to Optimize.

Click on "Automatic Expansion Settings".

Here, select the campaign you would like to use for automatic expansion. In order for Lightning AI to run, you'll need to setup this campaign with 1 ad set. This ad set needs any targeting settings you would like in future ad sets (e.g. demographics, geo), a few interests that are relevant for your users (e.g. my users like 'cats') and any ads you'd like to copy into future ad sets.

Then, you have two choices. Lightning AI will either build a certain number of new ad sets per day, or will determine the right number to create based upon your budget.

Click the option you'd prefer, fill in the details, and turn on automatic expansion!

Expansion runs once a day, usually in the middle of the night. If you'd like to create new ad sets at another time, just click on "Run Automatic Expansion" in Optimize.
