Suppose you manage a small restaurant in mid-town Manhattan. In the morning, you run multiple ads geared toward breakfast menu items and during lunch time you run multiple ads geared toward lunch menu items.
You are wondering which of your ad copies (headlines) works the best at different times of the day. How would you determine this using AdWords reports in Google Analytics?
In the above screen shot, notice that "Learn with Webucator" is a headline that works for us during the afternoon and the headline "Try a Webucator Course" is not that effective in bringing traffic or revenue.
