Think of it this way: instead of handing out flyers manually, we can now show ads to specific people who are actually interested in your restaurant. It’s like being able to hand flyers only to those who are already looking for a place to eat.
In the past, the flyer technique worked because it put restaurant information in the hands of the right people. Today, digital advertising does the same but with much greater precision and efficiency. While not everyone who sees your ad will visit your restaurant, it will reach those who are most likely to do so.
