Context: I run a coaching offer targeted to Remote Closers using Meta Ads. I'm an intermedia media-buyer - but the challenge I'm having is knowing when to cut an ad. Currently spending ~$10k m/o on ads currently. My original strategy was to load up my creatives(usually 5-7) into a 1 campaign with 1 ad-set (using our winning audience), and let it run for 3 days @ ~$250-500/day. On the 3rd day I'd look at sales, cost per booked call, and lead cost (in that order) and anything that wasn't producing leads, calls, or sales - I'd cut and declare a loser. However... I've seen people recommend spending 2-3x your TCPA (right now is $860 for us) and then look at an ads performance. Others like to give ads a certain amount of spend. Which brings me here asking -- When do you guys typically declare an ad a loser?
