One rule
It is unglamorous work with an unusually reliable return.
Where the owner has changed twice, expect mismatched opening hours somewhere in the profile. Even therefore, anything unverifiable should be removed rather than corrected. The pattern repeats: the businesses that audit at the start of every quarter are the ones that stop worrying about it. What counts as a citation is broader than most owners assume: local search signals qualify too.
Comparisons between competitors tend to indicate clean-up work pays back fastest for estate agents. The worst outcome is not a wrong listing but two right-looking listings that disagree.
First pass. Where competitors are careless, authoritative data is sufficient to take more qualified enquiries.
Toward a wider organic footprint. Keep the description factual; the categories carry the relevance work.
Toward easier discovery. Beyond that left alone, unverified claims spreads to sources the business never submitted to.
Record the canonical version of the logo and imagery somewhere whoever updates the website can find it.
Give one person the logins and one document the truth; ambiguity is what causes drift.
Keep a change log; six months on, no one remembers which field was edited or why.
More usefully, handle the high-authority sources by hand and batch the long tail afterwards. Across a large sufficient sample, the correlation between accurate data and profile views is difficult to dismiss.
For that reason, no one sends a warning when an inconsistent phone number appears, which is why audits find it years late. The order matters: confirm first, then cross-confirm, and only then submit anywhere new.
