Paid search reaches somebody who has just announced what they want. Paid social reaches somebody who was looking at something else, and everything that is different about buying it follows from that. The targeting matters less than most proposals suggest, the creative matters far more, the measurement is looser, and the thing that exhausts a campaign is not budget but the audience having seen the same advertisement too many times.
Creative volume is the deliverable, not an extra
On these platforms the same advertisement stops working within weeks because the audience has seen it, and the account then needs new material rather than new bids. A retainer that includes two creatives a month is buying a campaign that declines for three weeks out of four. Ask specifically how many new concepts and variants are produced monthly, who makes them, and whether that is inside the fee or billed on top; it is the most common hidden cost in this category.
Targeting has narrowed and the machine does more of it
Detailed interest targeting has been reduced across the major platforms, and the systems increasingly find the audience themselves from the creative and the conversion signal. That makes the old craft of audience building less valuable and makes the quality of your conversion data and your creative more so. A proposal built mainly around audience segments is describing a version of these platforms that has been going away for years.
Expect to be measured with less precision than search
Platform-reported conversions are generous to the platform, browser and operating-system privacy changes have removed much of the per-user tracking, and the same sale can be claimed by several channels. The honest tools here are geographic or time-based holdouts, incrementality testing and watching total revenue against total spend. An agency reporting a return that would be excellent if true, with no holdout ever run, is reporting the platform's own arithmetic.
Own the business account and the pixel
The advertising accounts, the business manager, the pixel and the audience data should exist under your ownership with the agency added as a user. The conversion history has real value and rebuilding it costs months. Agencies that run your advertising inside their own business manager are holding the asset you paid to build, and the moment that matters is the moment you want to leave.
Judge it against a channel you can already measure
The most useful benchmark is not a platform benchmark, it is your own search or email performance, because those are measured the same way by the same team. If paid social cannot beat them on cost per real customer after a fair test with enough creative behind it, it may simply not be a good fit for the product, which is a legitimate outcome and one that few agencies will volunteer.
Questions people ask about paid social media services
How is paid social different from paid search?
Nobody asked. Search captures stated demand; social interrupts, so the creative does the work that the query does in search, and the measurement is looser. Products that are hard to explain in a still image struggle here regardless of budget.
How much creative does a campaign need?
More than most retainers include. Advertisements wear out within weeks, so a steady supply of new concepts, not variants of one, is what keeps an account working. Ask how many are produced monthly and by whom.
Can we trust the platform's reported conversions?
As a directional signal, not as an accounting figure. The platform grades its own work and privacy changes have made per-user attribution partial. Run a holdout or a geographic test before drawing conclusions about incremental revenue.
Who should own the ad accounts?
You should, with the agency added as a user. The pixel history and audiences take months to rebuild, and an agency holding them inside its own business manager holds the thing you paid for.
