Any recommendations for making a daily budget last the whole day? I tend to find myself running out of my budget early in the day and either kiling my campaign or increasing the daily budget.
Go to campaign settings and make sure the budget isn't set to 'accelerated'. Each to their own, but I choose to have my budget run out as quickly as possible - it's a sure fire way of knowing whether your budget is too small, or whether you are perhaps bidding too high on some keywords.
Reduce your bids until your budget runs out just as the day ends (on average). This will maximise the number of clicks that you get for your budget. Then adjust the bids according to conversion rates to maximise the number of conversions that you get for your budget.
