How many ad variants should I test?
Start with three that change the angle, not three that change a single adjective. Otherwise you will not learn what the buyer responded to.
Write three testable ads from one offer, with a clear destination and no invented proof.
Illustration of one variant: headline "Reminders inside the booking tool," body "Practice managers cut the extra dialer step," call to action "Book a workflow review," destination the demo page. The ad copy generator can produce two more angles. It will not add a performance claim you did not enter.
Start with three that change the angle, not three that change a single adjective. Otherwise you will not learn what the buyer responded to.
Only when it is yours or you have permission and a source. The generator will not create one.
Treat the draft as a starting point and trim it to the placement you are buying. Do not assume a limit was applied.
