We are getting 24% as total ad cost / total spend.. & We think its really worth doing external ads on Amazon. But there are times that are ads are being shut down since we run of daily budget. We set our budget limit to 10USD a day. Do you think its worth the risk to increase our daily budget to 15USD per day? I'd like to submit a report to my boss with this, but I dont know exactly what to say. Anyone can help me?
