So people search for stuff online, but sometimes it's for a local product / service and sometimes it's for something purchased online. How do I figure out that percentage? For example, someone searching for a BURGER or a NAIL SALON, obviously, is looking for a local solution. But someone looking for a DIAMOND RING or an ESPRESSO MACHINE might be more likely to buy online.... TIRES .... obviously, is more of a local thing. But HOW do you estimate the % of local vs national searches for any given widget or service? Anyone know?
