Ask What should a business do when their best performing ad suddenly stops converting for no clear reason?

[Brajet]

It happens more often than people think. An ad that was bringing in sales for weeks can suddenly go quiet without any obvious reason. Before panicking, it makes sense to check if the audience has seen the ad too many times already, since people tend to ignore ads once they get too familiar. Checking the landing page, the offer, and even the season can help too. Sometimes fresh creative brings it back to life. What usually causes a strong ad to lose its power like that?
