Last month 3 days continue earn about $25 per day. But now, zero. Try to figure out what happen and increase daily earning. How about you?
How many days has it been at zero? If it's only a couple and you didn't change anything, it's probably due to market fluctuations. People just might not be searching for the keywords as much, or might not be looking to buy on the off days.
That's more than 2 weeks. What is your budget set per day per campaign. May think to increase the spend limit.
You using adwords? If yes, how much you spend per day? I think i should ask how much you earn with CB together how much you spend
