A paid social agency runs advertising on social platforms, mainly Meta (Facebook and Instagram), plus LinkedIn, TikTok and YouTube where they fit, to produce leads or sales at a target cost. It is often confused with a social media management agency, which posts content and grows followers. Both are legitimate. They are different jobs, judged on different numbers.
What a paid social agency actually does
Creative testing. On social platforms the creative is the targeting. The algorithm finds people based on who responds to the ad, so the agency's main job is producing a steady flow of new concepts, testing them, and scaling the winners. The creative testing framework we use describes the cycle.
Account structure and budgets. Fewer, larger campaigns that give the platform enough conversions to learn, with budgets moved towards what is working.
Conversion signals. Setting up the pixel and server-side events so the platform optimises for real outcomes, such as qualified leads or purchases, rather than clicks.
Reporting in business terms. Cost per lead, cost per customer, return on spend. Not reach and engagement.
Paid social agency vs social media management
A social media manager plans a content calendar, posts, replies to comments and grows the page. Success is measured in followers, engagement and brand presence.
A paid social agency may never post on your page. Its ads run from the ad account, often to people who have never seen your profile. Success is measured in customers and what they cost.
If your goal is enquiries or sales, you need the second, and an agency that offers "social media" without specifying which is worth questioning closely. We set the two side by side in paid media agency vs performance agency.
Which platforms a paid social agency should use
Meta for most consumer businesses and many B2B ones, because of reach and the strength of its optimisation. LinkedIn for B2B where the buyer's job title matters and deal sizes justify the higher cost; LinkedIn ads arithmetic covers when it pays. TikTok and YouTube when the audience is there and the brand can produce native video. An agency that recommends every platform for every client is spreading your budget too thin to learn anything.
How to choose one
- Ask how many new creatives they produce per month, and who makes them.
- Ask what conversion event they would optimise for in your account, and why.
- Ask for a case study with cost per customer, not just reach.
- Ask whose ad account the spend runs through. It should be yours.
- Ask what they would tell you to fix before spending: offer, landing page or follow-up.

Questions people ask before hiring
What is the difference between paid social and social media marketing?
Paid social is advertising run from an ad account to produce leads or sales, judged on cost per customer. Social media marketing usually means organic posting and community management, judged on followers and engagement.
Which platforms does a paid social agency cover?
Mainly Meta, plus LinkedIn for B2B, and TikTok or YouTube where the audience and creative capacity fit. A good agency concentrates budget on the platforms that suit your buyer.
How many ad creatives should a paid social agency produce?
Enough to keep testing new concepts every week. Creative fatigue sets in within weeks on most accounts, so an agency rotating the same few ads for months is leaving results on the table.
Should a paid social agency also manage my page?
It can, but the two are separate skills. If you need both, ask who does each and how each is measured.
