Bakery demand runs on a clock unlike almost any other retail food business. The heaviest search volume lands between six and ten in the morning, on a phone, within walking or short driving distance, and the decision is made before the searcher finishes reading the second result. Photos of the case, this morning's hours, and whether the espresso bar is open decide it. Nothing about that visitor is a lead in the traditional sense, and measuring the campaign as if it were will make a healthy bakery look like it is failing.
Sitting on top of that is a completely separate, high-value demand curve: celebration and wedding cakes. Those searches carry planning language rather than proximity language, the buyer compares four or five bakeries across a weekend, asks about tiers, flavours, tastings and deposits, and books anywhere from six weeks to a year out. This is where a bakery's revenue per order stops being a few dollars of pastry. The searcher needs an order path, a price range, a lead-time policy, and evidence you have made the thing they are picturing.
Layer seasonality on top and the year has hard, predictable spikes: holiday pie and cookie preorders, Valentine's, graduation season, and the wedding calendar's spring and autumn shoulders. A campaign that goes live in November for pie season is late. Add the fastest-growing query family in the category, dietary searches for gluten-free, vegan and nut-free baking, and a corporate catering audience that searches during the work week for something entirely different from what the weekend visitor wants.
