The short answer
Hire a social media manager when posting, replying and reporting take more time than anyone on the team has, and when social media matters enough to the business to deserve one owner. Look for someone who can plan, make, write, reply and read numbers, judge them on a paid trial task rather than their own follower count, and give them a clear goal, a brand voice guide and the authority to post.
Much of the job is now replying, and replying fast. In Sprout Social’s Q2 2026 survey of 2,250 social media users, 84% said a brand’s response speed affected how they viewed a problem, and 64% said it was important for brands to respond publicly on social media. The person you hire is the brand’s voice in public, often within the hour.
What a social media manager does
The job spans the whole loop, and the volume adds up: at the rates Buffer’s 2026 frequency guide suggests, such as 3 to 5 Instagram posts and 2 to 5 LinkedIn posts a week, one person running three platforms is publishing most days, before a single reply.
| Part | What it involves |
|---|---|
| Plan | Strategy, content pillars, the calendar, campaigns |
| Make | Photos, short videos, carousels, captions, or briefing others who make them |
| Publish | Scheduling every platform’s version, on time |
| Talk | Replying to comments, messages and reviews; handling complaints |
| Learn | Reading results against the median, reporting, adjusting the plan |
| Protect | Account security, approvals, and acting fast when something goes wrong |
In-house, freelancer or agency
An in-house hire knows the business best and can reply as part of it, but is one person with one set of skills. A freelancer is flexible and often specialised, but shares their time with other clients. An agency brings a team and a process, but costs more and knows the business less at first. Many small businesses start with a freelancer for making and keep replies in-house, because replies need knowledge of the business that is hard to hand over.
What to look for
The skills that matter most, in order:
- Judgment: knowing what to post, what not to post, and when to stop and ask.
- Writing that sounds like your brand, not like a template.
- Making short video and images on a phone, quickly and well.
- Reading numbers: comparing posts with the median, not chasing likes.
- Calm under criticism, and care in replies.
- Organisation: a calendar that runs weeks ahead.
Interview with a task
A candidate’s own account says little about what they would do for you. Instead, give a short paid task: plan a week of posts for your business across two platforms, write three captions in your voice, and answer two real comments, one happy and one angry. Judge the judgment and the voice as much as the polish, and talk through the choices afterwards.
Set them up to succeed
Give the new manager a clear goal with a number and a date, the brand voice guide, access to every account through their own login and role rather than a shared password, an approval path for sensitive posts, and the authority to reply without waiting. Agree how you will review results each month. A manager who has to ask permission for every post cannot reply within the hour.
The first 90 days
A new manager’s first month is for learning: auditing every account, reading the past six months of results, meeting the people who know customers best, and writing down the voice. The second month is for a steady calendar and fast replies. The third is for the first changes, judged against the median from month one. Agree this rhythm up front so nobody expects a transformation in week two.
How a team grows
Teams usually grow in a predictable order. One person does everything; then making is split off, to a designer, video editor or freelancer; then community management, so replies stay fast; then analytics and paid social. At each step, write down who owns which part of the loop, keep one calendar everyone sees, and keep the voice guide current so the brand still sounds like one person.
Questions
When should a small business hire a social media manager?
When posting, replying and reporting take more time than anyone has, and social media brings enough business to deserve one owner.
What does a social media manager do day to day?
Plans the calendar, makes or briefs posts, schedules them, replies to comments and messages, and reads results to adjust the plan.
Is it better to hire in-house or use an agency?
In-house knows the business and replies best; an agency brings a team and a process. Many small businesses use a freelancer for making and keep replies in-house.
How do I test a social media manager candidate?
With a short paid task: a week’s plan for your business, three captions in your voice, and replies to one happy and one angry comment.
