What does a social media agency do best?
A social media agency does creative direction and heavy production best: brand campaigns, video shoots, design systems, and the strategic thinking that decides what a brand should sound like this year. Those need people, equipment, and taste developed across many clients.
What an agency is rarely staffed for is the always-on feed: a native post per platform every day, replies drafted within hours, and a memory of which hooks worked last month. That cadence is expensive to staff with humans and is where most retainers quietly thin out.
What does a Social Growth FTE do best?
A Social Growth FTE does the always-on feed best: a calendar proposed weekly, every post written natively for its platform, published on your approval, replies drafted, and a per-brand memory that improves the next week. It works daily and reports on engagement-weighted reach.
What it does not do is shoot video, design a visual identity, or set the creative direction for a launch. It executes a brand's voice inside rules it was given; it does not invent the voice.
How does community management differ?
Community management is where the control model matters most. An outsourced inbox typically gives a junior team member authority to reply on the brand's behalf, with escalation depending on their judgement at the time.
The Social Growth FTE drafts routine replies for approval and escalates sensitive ones by rule: complaints, legal matters, journalists, safety concerns, and excluded topics always reach a named person and are never auto-sent. The rule holds at every autonomy level, which is a stronger guarantee than a training session.
- Cadence: campaign-based batches versus a daily native feed
- Replies: junior judgement versus rule-based escalation
- Memory: in the agency's heads versus inspectable and yours
- Cost: retainer versus metered work
- Creative production: agency strength versus not the FTE's job
Whose memory is it?
An agency's knowledge of what works for your brand lives in the heads of the people on your account, and it leaves when they rotate. The Social Growth FTE keeps that knowledge in an inspectable per-brand memory that stays with the brand.
That memory is also correctable. If the FTE has drawn a wrong conclusion about your audience, you can see it and fix it, which is not something you can do with an account team's intuition.
How should you decide?
Decide by asking where your current spend goes and where your current gaps are. If the feed is thin between campaigns and replies lag, the FTE addresses the gap. If the campaigns themselves lack direction or production quality, that is agency work.
Running both is common and honest: the agency directs and produces the campaigns, and the Social Growth FTE keeps the feed alive and the inbox handled between them, with the agency's direction encoded in the FTE's brand rules.
How do you compare them without a vanity metric?
Compare them on what each actually produces rather than on follower counts. For the agency, record over a month the posts published per platform, the replies handled, the turnaround from a brand event to a post, and the retainer. For the Social Growth FTE, over the same length of time on the same accounts, record posts proposed and approved, send-back reasons, replies drafted and escalated, turnaround from event to proposal, and tokens consumed plus your approval time.
Then look at the differences that matter more than reach. Native per-platform drafts versus cross-posts. Replies that reached a person because the remit escalated them versus replies an account manager answered on the brand's behalf. A Brand Brain you can open and correct versus a voice held in an account team's heads. Where your data allows it, engagement per post over the two periods is a fair comparison; where it does not, the honest answer is unmeasured, and the FTE's performance view will say so. The decision usually comes down to whether the daily voice should live in your workspace or in theirs.
