Hello,
today I used my FB Pixel on a thank you page to create a custom audience. The size of that
audience is 17,000. After that I created a LAA from that CA. While creating the audience FB estimates the size of the LAA 2,140,000 people. But after creating the audience the size is less than 1,000 people.
How can that be?
I repeated the process 3 times. Always ended up the same.
Any help is welcome.
You need to give it more time, <1000 simply means it is still crunching numbers. Usually, the real size will appear within one day.
Thanks. That helped.
