Define the actual responsibilities
Content planning.
Copywriting.
Graphic or video production.
Scheduling.
Community replies.
Analytics.
Reporting.
Campaign coordination.
Separate strategy from production
A strategist, creator and community manager may be different people. Do not assume one freelancer is equally strong at every part.
Clarify account access
Use appropriate permissions and keep critical account ownership under business control.
A posting calendar is not automatically a social strategy.Define the audience, objectives and content system before measuring activity.
Agree on approval rhythm
Specify which content requires approval and how quickly the buyer must respond to avoid blocking the schedule.
