Any AI system does not work automatically, it must first be trained. This training process is called machine learning (ML)

Later, the more machine learning is taught, the more advanced it will become, and at some point it will become deep learning. This process is called (DL)

When he learns enough, the artificial intelligence within him will start working automatically.

What did a user do on which page of a website, for how long? And what product did he view? The more all this data can be given to Facebook's Business Manager, the better results he can bring.

It can also be seen that a user is not always in a buying mood, but he adds a product to the cart on the website. Later, through tracking, the advertisement can be brought to him again, which increases the possibility of sales.

1. 30 to 40% of users come to the website through the campaign
2. But There is a 3% chance of a user making a purchase who comes through the campaign.
3. Average Add-to-Cart (ATC) Rate in E-commerce-6.2%
4. Global average purchase conversion rate (from ATC): ~25%-30% 

And if all these events can be tracked, the campaign can be retargeted to the user, knowing how much time they spent on the website.
