Let's say I have a custom audience of website viewers to my site with 3000 visitors.
I made a 1% Lookalike audience for a total of 2 million visitors.
As time goes by and with more visitors, there will be difference in the visitors for the lookalike audience.
So the question is, do I have to constantly update the lookalike audience every 1-2 weeks, or will the audience automatically update with more visitors, turning it into a self fulfilling system?
Thanks for your help!
Lookalike audiences will automatically update every 3-7 days to reflect changes to your source audience.
