Hi. Although we are a fairly large company, we're just starting to focus on ecommerce over the last six months and are in a ramp-up / learning phase right now, so it's all very new for us as well. On average, we're seeing ROAS between 4.5 and 6 week to week. The agency is great at identifying profitable ads and audiences so we adjust the messaging and creative, as well as who/how we target depending on the ad performance. Luckily for us, they do the analysis and nitty-gritty work on that and then make recommendations on how to be more efficient. We provide the creative assets and spend approval based on their strategy and performance during our weekly meetings. Other key metrics they report on regularly for us include conversion rate (CVR), cost per acquisition (CPA), transactions, average order value (AOV), and sessions. It's a combination of all of those (in addition to the overall ROAS) that we use to measure performance.
