The market cost per click is higher than you can afford at this margin. Raise price, improve conversion, or choose narrower keywords before spending.
You need roughly 100 clicks per ad group per month to learn anything. If the budget above buys fewer than that, spend it elsewhere until margins or conversion improve.
