Is it possible to build up your lead pixel from native and have it fire back into facebook so that you can create custom audiences off of that and LLA's?
For example, I advertise in Nativo native and have my facebook code on my site. Facebook still records the "lead" events. Then use those lead events to create a custom audience and a LLA? I have tried and I get a write error.
Any idea if you can do such a thing?
If your facebook pixel is correctly firing after the user completes all the required leadgen fields, then you're good.
You can also use this technique to create custom audiences on other native traffic sources as well.
Apparently, you have a very small audience to create a similar audience. Try to collect events (if they are properly configured) and it should work out
