In the Greater Seattle area, you never know what spring weather will bring -- cloudy at 8 a.m., sunny at noon, pouring down rain at 5. I always start the day with a check of the forecast, so I know what to expect.
In the same vein, anyone planning a search advertising campaign should know what the day's search "forecast" might be.
That's because search isn't a static thing. Search behavior changes each day, during the day as well as on different days of the week. Those changes can take the form of different user intent, different search volumes, different devices, or all three.
