Ask How do you split test ad copy in Google Ads without messing up the data?

[Newman]

Split testing means running two versions of an ad to see which performs better. The safest way to do this in Google Ads is to change only one thing at a time, like the headline, and keep everything else the same. Running both ads in the same ad group and letting Google rotate them evenly gives cleaner results. The problem starts when you change multiple things at once because then you cannot tell what caused the difference. How long do you usually run a split test before you feel confident making a decision?
