How To Season A Facebook Pixel

As of: 2019

From the Facebook Blueprint training manual:

Season a new Facebook Pixel:

1. If there were less than 500 pixel events on your website in the last week, build up your online customer base before using Conversion optimization.
2. If there are more than 500 but less than 10,000 pixel events on the website in the last week, you should start in testing your conversion optimization.
3. If there are more than 10k pixel events on your website in the last week, you’re in a good position to make conversion optimization work.

At any rate, once your pixel is active, you will need at least 50 conversions (best to have 100) per week to exit the “learning phase” and achieve optimal delivery.
