5 things I've learned after testing well over 1000 ads on Youtube. In short form. 1) Good creative makes media buying easier, When you have scalable ads, you can target completely broad with 50k/day campaigns. 2) The hook/lead is everything. The first 1-30 seconds is where you'll want to put the majority of focus on 3) Test. Test constantly. Test different angles. Test different formats. Consistently test. Those who don't are lazy. 4) Create variations for winners. When you find winning ads, create variations of that winning ad. That's easier than having to create new angles all the time. 5) Become obsessed with details. When you test this many ads, you have to become more detail-oriented for optimization. What are you testing in the ad? Why? Does your test make sense or are you just testing shit 'for the sake of testing'? Are the video edits in line with the right conversion elements?
