Managing a PPC budget starts with knowing how much can be spent without hurting the business. A daily or weekly limit is set so spending stays under control. Money is shared more on ads that bring clicks or sales and reduced on ads that perform poorly. Small tests are useful before spending more, because not every ad works the same way. Costs should be checked often to avoid waste. When results are clear, the budget can be adjusted slowly. What method do you think works best for keeping spending under control?
