A social advertising agency buys attention on platforms where nobody arrived intending to buy anything. That is the whole difference from paid search, and it decides what good work looks like: creative volume matters more, the offer has to earn the interruption, and measurement is harder because the click and the purchase are often days and devices apart. The market is crowded and the barrier to entry is a login, so vetting matters. This page covers what the work actually consists of, the platform rules that constrain it, how agencies charge, and the questions that tell an operator from a reseller with a media buying template.
What the work actually consists of
Four things, in descending order of how much they move outcomes. Creative, because on an interruption channel the ad itself carries most of the performance and the only reliable way to find a winner is to test many. Offer and landing experience, because interrupted attention converts only when the next step is obvious and low friction. Audience and campaign structure, which matters less than it used to as platforms automate targeting, but still decides what the system is optimising toward. And measurement, which is the part most agencies are weakest at and the part you cannot outsource your judgement on. When you read a proposal, count how much of it is about creative production capacity. A social agency that cannot produce volume is buying media it has nothing good to run.
The rules the platforms actually enforce
Meta's advertising standards state that its ad review process starts automatically before ads begin running and is typically completed within twenty four hours, although it may take longer in some cases, and that ads must not promote products, services, schemes or offers using identified deceptive or misleading practices. Whole categories are restricted, including alcohol, tobacco, weapons, gambling, cryptocurrency and certain pharmaceuticals. Most consequential for planning: any United States advertiser, or advertiser targeting the United States, Canada or certain parts of Europe, running financial products and services, housing or employment ads must self identify as a Special Ad Category, which limits targeting options. If you are in housing, lending, or recruitment, that constraint shapes the entire media plan and any agency that discovers it after launch has cost you a cycle.
Endorsements, creators and who carries the liability
Creator-led advertising is where social differs most from search, and where the compliance exposure sits. The FTC's guidance is that if there is a connection between an endorser and the marketer that a significant minority of consumers would not expect, that connection should be disclosed clearly and conspicuously, and that endorsements must reflect the honest opinion of the endorser and cannot be used to make a claim the marketer could not legally make. Employees posting about their employer should disclose the relationship. The line that matters commercially is this: your company is ultimately responsible for what others do on your behalf, and you should make sure your agency has a programme in place to train and monitor the people posting. So ask to see the disclosure standard the agency uses and how it audits compliance, before a creator campaign runs rather than after a complaint.
How agencies charge, and what each model rewards
The same three models as paid search, with the same incentives. A percentage of ad spend is simple but pays more when you spend more. A flat management fee decouples the fee from the budget and rewards discipline, but can leave a large account thin on attention. Performance pricing sounds ideal and depends entirely on attribution being clean, which is exactly what is in dispute when results disappoint. Social adds a fourth variable that search does not: creative production. Ask explicitly how many new creative concepts per month the fee includes, who shoots and edits them, and what an extra batch costs. An agency whose fee covers management but not creative is selling you the cheap half of the job.
The questions that separate operators from resellers
Ask who works on the account by name and how many accounts they carry. Ask to see a real testing plan: how many concepts run at once, on what budget, and what threshold retires a loser. Ask how conversions are measured and how the agency reconciles platform-reported results with your own records, because on social those two numbers rarely agree and the explanation for the gap is the real test of competence. Ask who owns the ad account, the pixel or conversions API setup and the creative assets, and insist they sit in your name. And apply the general hiring norms Google publishes for search suppliers, which travel well: be wary of unsolicited pitches, of claimed special platform relationships, and of anyone unwilling to explain their methods clearly.
Questions people ask about social advertising agency
How is social advertising different from paid search?
Search captures existing intent; social interrupts it. That shifts the work toward creative volume and offer quality, makes measurement harder because the click and the purchase are often separated in time, and means a media plan without a creative production plan attached is only half a proposal.
Why do platform-reported conversions differ from my own numbers?
Attribution windows, cross-device journeys and modelling differ between a platform's reporting and your own records. A competent agency will tell you which numbers it is quoting, reconcile them against your source of truth, and explain the gap rather than pick whichever figure looks better.
Do we need special approval for housing, lending or job ads?
On Meta, yes. Its standards require any United States advertiser, or advertiser targeting the United States, Canada or certain parts of Europe, running financial products and services, housing or employment ads to self identify as a Special Ad Category, which restricts targeting. Plan for that before the media plan is built.
Who is responsible if a paid creator fails to disclose?
The advertiser. The FTC's guidance is that your company is ultimately responsible for what others do on your behalf and that you should ensure your firm has a programme to train and monitor its people. Ask to see the agency's disclosure standard and its audit process before a campaign runs.
Who should own the ad account and the pixel?
You should. Keep the ad account, conversion tracking and creative assets in your own name and grant the agency access, so a change of supplier is a permissions change rather than a rebuild and you keep the account history.
