NAP consistency

What NAP consistency means
Agreement of a business's name, address and phone number across its own site and every directory that lists it. The phone number does most of the work, because it is written the same way everywhere and rarely shared; a listing that prints a different name on the same number is a second entity to a retrieval system.
