Most damage here is self-inflicted: an abandoned profile introduced during a rebrand or a move, if only since nobody else bothers.
Anything unverifiable should be removed rather than corrected. The worst outcome is not a wrong listing yet two right-looking listings that disagree. Getting this right buys more qualified enquiries without touching the website at all. For that reason, get the facts to agree, and business data providers will do the rest without being asked.
On the other hand, where competitors are sloppy, verified data is enough to take ranking stability. The finish line is not perfection; it is a profile that nobody has to argue with. More often than not, the cost of contradictory data across sources is not a penalty; it is being unobtrusively ranked below someone tidier.
Generally, nobody sends a warning when duplicate profiles shows up, which is why audits find it years late. It is one of the cheapest routes to improved local relevance still available across several trading areas, once the obvious errors are gone.
A misplaced service area is easy to miss since nothing visibly breaks. Handled steadily, business listings stop being a project and become a habit. Set aside time to monitor at the start of every quarter rather than treating it as a one-off project.

Start by pulling every existing record into one sheet before changing anything. Generally, the gain is rarely dramatic on any single day; it indicates up as stronger trust signals over a quarter.
It is unglamorous work with an unusually reliable return. Left alone, thin descriptions spreads to sources the business never submitted to.
A workable routine is to audit as part of the monthly reporting cycle and log every change with a date. Keep the record complete, revisit it at least annually, and most local problems solve themselves. Owners often catch branded queries moving before they catch the ranking change itself.
