Traffic is not constant from day to day. For example, fewer people search the Web on weekends than during the week. Google may allow up to 20% more clicks than your daily budget limit one day.However, under no circumstances will you pay more in one month than your daily budget limit specifies. For example, if you budget $100 per day in a 30-day month, you may receive more than $100 in clicks one day, but the maximum you would pay is $3,000 for that month.
