Daily Budget
To change your daily budget, click on the current value at the upper-right of the campaign information box, enter a new one and move you cursor away from the field.
If you have a fixed budget for your campaign that you cannot modify under any circumstances (or only under extremely unique circumstances) you should keep your budget at the level. However, if you have some flexibility with your budget based on campaign performance, we advise that you make your budget about 50% higher than you normally spend on a daily basis, so that your campaign can continuously earn and grow without arbitrary constraints.
The Clickable Act Engine will also help you maintain your campaign’s budget. If your campaign is performing well but tends to use all or most of its budget on a regular basis, the Act Engine will advise you to increase your daily budget in order to remove limitations to your campaign’s growth. However, if your campaign is performing poorly, we would advise you to reduce costs by reducing keyword bids within that campaign rather than reducing your campaign’s budget.
