We split the campaign into prospecting and retargeting. For prospecting, we targeted broad audience and remarketed audience who viewed the ads, then optimized towards add to cart. For retargeting, we targeted lookalike audience as well as those who viewed and added to cart from our ads, then optimized towards purchase. Then setting the period – prospecting 1-11 Ocr, retargeting 8-11 Oct.
We also split the campaign into 3 phases – Teaser (1-11), D-day (10), and Clearance (11). Each phase had 3 creatives material that consisted promotion. We put all the creative into each campaigns and manually turning on the creatives which was on scheduled on the ads level.
We also didn’t use Campaign Budget Optimization, but set the daily budget manually and weighted more on days that resulted high number of purchase (D-2,D-1, D-day, D+1)
