What Does a Social Media Agency Do?

A monthly retainer should buy a repeatable operating system, not an unexplained number of posts. This guide shows Metro Vancouver business owners what social media management can include, which responsibilities remain with the business and how to compare proposals without assuming every agency uses the same scope.

Short answer

A social media agency can handle audience research, monthly planning, content production, platform-specific writing, approvals, publishing, community management and reporting. The exact retainer should state the channels, deliverables, production time, response coverage, revision limits and separate costs so the business knows what happens every month.

01

What does a social media agency do each month?

A useful monthly scope connects planning, production, approvals, publishing, replies and review in one documented cycle.

The visible posts are only the final output. Before anything is published, someone needs to confirm business priorities, research customer questions, choose topics, gather accurate source material, schedule production and adapt each idea to the channels in scope. After publishing, the work may include comment replies, inquiry routing, performance review and the next round of decisions.

Not every social media agency includes every task. Some retainers are strategy-only, some focus on content creation and others provide full social media management. The proposal should name the owner of each task instead of using broad phrases such as ongoing support or full service without definitions.

02

Does a social media retainer include strategy?

Strategy should be visible in the audience questions, channel choices and monthly priorities that guide production.

A calendar is not automatically a strategy. The agency should be able to explain who a post serves, which question it answers and what useful next step it supports. For a Vancouver service business, that might mean improving local visibility around location, price, first visits or language support rather than filling a month with generic awareness dates.

Good planning also separates platform roles. Instagram may support visual familiarity, while RedNote (Xiaohongshu), a Chinese social-search and discovery platform, may require Chinese-language research and more detailed decision content. Copying one caption into every channel reduces the value of the retainer even when the publishing count looks high.

  • A short review of the previous month and current business priorities
  • Customer questions and search themes worth addressing
  • A defined role for every channel in scope
  • A content calendar with owners and approval dates
  • A plan for time-sensitive offers, closures or operational changes

03

What content production should be included?

The retainer should specify how original photos, video, design and writing are created, revised and delivered.

Production scope is often where two similar-looking quotes become very different. One plan may assume the business supplies every image. Another may include a monthly location shoot, short-form editing, cover graphics and bilingual writing. Ask about production hours, travel area, revision rounds, source files and whether unused assets remain available for future content.

A Richmond restaurant, Burnaby clinic and Coquitlam professional-service office will not need the same capture rhythm. The useful schedule follows real access and customer questions. More production is not automatically better if the resulting material does not help customers understand the business or move toward an inquiry.

04

Are publishing and community management included?

Publishing and community work may be included, but the agreement should define channels, hours, response boundaries and escalation rules.

Publishing includes more than pressing a schedule button. Captions, tags, links, crops, cover frames and current business details should be checked in the final channel format. If the business approves content late or changes an offer, the retainer should explain how the calendar moves and whether rush revisions cost extra.

Community management can cover routine comments and general questions, while pricing exceptions, booking availability, complaints and regulated advice should move to an authorized employee. A clear handoff protects both customer experience and the business. It also makes it easier to see whether social media marketing is producing more useful conversations rather than only passive views.

05

What should a monthly social media report show?

A useful report connects content activity with discovery, customer actions and specific changes for the next month.

Reach and follower movement can provide context, but they should not be the whole report. Review which topics led to saves, profile visits, website clicks, direction requests or qualified questions. Where the business can track it responsibly, compare those signals with calls, inquiry forms, reservation sources or recurring front-desk questions.

The agency should explain what it learned and what it recommends changing. Reporting earns its place in a retainer when it improves the next plan, not when it delivers a decorated spreadsheet without decisions. No report can prove that one post caused revenue unless the tracking and customer path genuinely support that conclusion.

06

What is usually separate from a social media retainer?

Advertising spend, creator payments, unusual production and third-party costs are often separate and should be listed before work begins.

Common separate items include platform ad spend, creator or influencer fees, product gifting, studio rental, actors, models, props, advanced animation, large event coverage, travel outside the agreed area and high-volume rush work. Website changes, email marketing and local listing management may also sit outside the social scope.

Black Mango Social currently publishes monthly plans from CA$1,200 to CA$2,480, with channels and production expanding by plan. Those are this studio's prices, not a market average. Verify the current service page and ask for a written estimate when the campaign needs creators, advertising or additional production.

07

How do you compare social media agency proposals?

Give each provider the same operating questions and compare responsibilities, limits and decision quality rather than post count alone.

A retainer is easier to manage when the business appoints one approval owner and the agency appoints one accountable lead. Clear communication does not remove the need for expertise, but it prevents good work from stalling between several inboxes.

    Review separate costs

    Identify advertising, creators, software and unusual production before comparing totals.

    Agree on learning

    Choose the signals and review cadence that will improve the next month's work.

Frequently asked questions

Direct answers, without the sales fog.

01 How many posts should a monthly retainer include?

There is no universal number. The right volume depends on channel, production depth, audience questions, approval capacity and whether the plan includes community work.

02 Does a social media agency answer customer messages?

Some do. The agreement should state coverage hours, approved response types, escalation rules and whether direct messages are included.

03 Are social media ads included in a retainer?

Strategy or management may be included, but platform ad spend is commonly separate. Confirm both the management fee and the media budget.

04 Who approves content before it is published?

The business should appoint an authorized approver who can confirm facts, offers and operational details by an agreed deadline.

05 Can an agency guarantee more customers?

No. An agency can improve consistency, local visibility and the inquiry path, but demand, offer quality, reputation, capacity and follow-up also affect results.
