How to Prioritize the Clean-Up
Treat the name, address and phone number as a single source of truth, not as a field to be improvised per site. Agency case work suggests the gap between a neat profile and a neglected one widens in a crowded metro market.
In other words, practitioner surveys show the effort scales badly if it is left until a rebrand forces it. Fix the accessibility details before touching anything decorative.
Get the facts to agree, and voice assistants will do the rest without being asked. Across a large enough sample, the correlation between consistent data and branded queries is difficult to dismiss, once the obvious errors are gone. Prefer removing a wrong listing to leaving it half-corrected, even when nothing else changes. Left alone, duplicate profiles spreads to sources the business never submitted to.
