Social Media Marketing
A social media marketing agency plans, produces, and posts a brand's content on platforms like Instagram, TikTok, LinkedIn, and YouTube, and manages the replies and messages that follow. Businesses hire them because staying visible on social is a daily production job most teams cannot sustain in house.
How they make money
Almost everything here is a monthly retainer scoped by platform count and posting volume, most commonly 1,500 to 8,000 dollars for small and midsize brands. The retainer usually covers strategy, a content calendar, creative production, publishing, and light community management. Paid social amplification is typically a separate fee, often 10 to 20 percent of ad spend, layered on when organic posts get boosted or full campaigns run.
Video heavy scopes cost more because shooting and editing short form video is real production work, and some agencies price it per finished video instead of inside the retainer. Influencer coordination, when included, is billed as a management fee on top of what creators are paid. Month to month terms are common, which keeps switching costs low in this category.

How the category is changing
Organic reach for brand accounts keeps shrinking on most platforms, and the agencies adapting have shifted from posting on behalf of a logo to producing content around people: founders, employees, and paid creators whose faces the algorithms favor. Short form video is now the center of nearly every scope, which pushes retainers up because editing capacity is the bottleneck.
AI has absorbed the low end. Caption writing, scheduling, and basic graphics are cheap or free now, so agencies selling only those tasks are losing accounts to software. The value has moved to what tools do not supply: creative judgment, on camera talent direction, community response, and knowing which format each platform is rewarding this quarter. Expect more agencies bundling creator sourcing and paid amplification with organic management, because the three are no longer separable in how the platforms actually distribute content.
