I start my google shopping ads for 6 days and it's totally no purchase at all. I'm a small bussiness owner which sell some handmade baskets and trays. My budget is $50/day and i do maximize clicks which set limit for $1/click. I do optimaze my nagtive keywords and other optimaze for my feed and website everyday, However still no conversion. I feel disappointed at the moment. Any professional suggestion to increase my ROAS? Should i wait my ads to learn more time or should i quite?
