Let us state it bluntly - the more Google searches occur for your concept or brand, the more likely you are to have higher sales.
Here is a graph showing how Google searches for the four largest pizza chains trend on a weekly basis. As you can see, there is a nice steady, consistent shape. The peak of each curve is Saturday and the lowest part of each curve is on Tuesday.
This may seem insignificant until you match it up with sales data. Across almost every restaurant concept and brand, weekends are the highest grossing days of the week and Tuesdays are the lowest.
A local small chain pizza restaurant was kind enough to share their sales data with us and here's what we discovered (note - we indexed their sales data per their request to protect their numbers):
As you can see, there is a very similar pattern to the above graph showing trends in Google searches. Clearly, there is a strong correlation between Google searches for a concept or brand and the sales that occur on that day. It shouldn't be surprising that Google searches are a direct precursor to in-store sales.
