Two Reasons Audits Stall
Broadly, it's unglamorous work with an unusually reliable return. In the main, local search rewards the ordinary and the verifiable more than it rewards the novel. Keep a change log; six months on, no one remembers which field was edited or why. It's one of the cheapest routes to a higher conversion rate still available across several trading areas.
The landscape shifts, but the underlying requirement; checkable, authoritative data; hasn't. Begin by pulling every existing record into one sheet before changing anything. More frequently than not, well-structured records are one of the few local levers that still work without a budget.
Where competitors are careless, complete data is sufficient to take visibility in the map pack. A business rarely disappears from local results overnight; it fades as its records go dated. Record the canonical version of the name, address and phone number somewhere the person on reception can find it.
