01What to drop
At the same time, set aside time to cross-verify before each campaign rather than treating it as a one-off project.
02Checking the business description
Anything unverifiable should be removed rather than corrected, particularly for a newer business.
03Worth checking
In the ordinary case, give one person the logins and one document the truth; ambiguity is what causes drift.
04The short list
The order matters: map first, then prune, and only then submit anywhere new, give or take a reporting cycle.
05One rule
In other words, keep a change log; six months on, no one remembers which field was edited or why.
