E-commerce: scaling the inflatable balloon store in Google ads

I have been developing an online store for inflatable balloons in Google Ads (USA / CA) for several years — from the start without historical data to stable scaling. Currently: 4,353 purchases in 30 days with an average CPA of CA$6.03 at a budget of ~CA$1,900/day. Other sources have also been involved: Bing / META. #GoogleAds #GoogleAdwords #GoogleAnalytics
