In what way does Al optimization increase attribution problems?

The ad networks are more successful at targeting people who are already likely to buy, so the ad networks can claim credit for purchases they did not cause

The Al optimization algorithms have been trained in the most efficient way to fabricate realistic$-$seeming data

Al$-$optimized ads are more likely to affect shoppers' behavior on other advertising platforms, increased cross$-$channel advertising effects

Al optimization increases the amount of random noise in the data, which makes it more difficult to measure which ads are producing conversions
