One a month I do what I call deep optimization on my ZeroPark campaigns. I optimize throughout the month (day-to-day and week-to-week a lot of times) but once a month I go through and analyze/optimize based on the past 30 days. This takes awhile but it's been well worth my time in the past months. Anyway I'm going to go through tomorrow or Monday and do my deep optimization for last month. I haven't had time...
