Media Buying
Media buying is the purchase of advertising placement: search results, social feeds, video, display, streaming TV, audio. It covers choosing channels, setting budgets, bidding in auctions, negotiating direct deals, and deciding what runs where. The craft has shifted from negotiating with sales teams to configuring platform auctions, and the platforms that run those auctions also report on how well the spend performed. That is a conflict of interest, and it affects every buying decision that follows.
How it actually works
Most buying now happens in self-serve auction platforms. You define an audience or a keyword set, upload creative, set a bid strategy and a budget, and the platform's auction decides which impressions you win and at what price. Direct deals and programmatic exchanges still carry premium inventory, but the auction model dominates search, social, and increasingly television.
The platforms keep moving buyers toward automation. Products like Google's Performance Max and Meta's Advantage+ take budget and creative, decide targeting and placement internally, and report results through their own attribution. The number that comes back counts revenue from people the platform showed an ad to, including people who were already going to buy. No platform can measure which of those purchases would have happened anyway, and each platform's incentive is a report that justifies more spend on that platform.
Buying well means allocating against what the spend caused, not what a platform credited. A buyer crosses several channels before purchasing, so channels have to be read together instead of in isolation. Holdout tests establish what happens when a campaign is off. Campaigns are judged on contribution margin and payback. Media also occupies a particular position on the P&L: for most companies it is the largest discretionary opex line, which makes it the fastest EBITDA lever a CFO has and the first line cut under pressure. The cut reads as pure savings in the quarter it lands because the demand the spend was creating decays on a lag, the same borrowing-from-future-demand mechanism our marketing insolvency entry describes. A buyer who can show which spend is incremental protects the productive share of the line when that conversation arrives.
In practice
At Potbelly, the work started at level budget: the same total spend, reallocated by what measurement outside the platforms showed was working. That made the spend five times more efficient before any budget was added. What changed was the message; the creative teams and the audiences stayed the same. Scaling came after the efficiency was proven, and the efficiency supported a 30% lift in revenue, with a further 19% the following year. The upper bound on ad efficiency is public. Tesla reached $81.4B in revenue and a trillion-dollar valuation with an ad budget of under $200k, about $0.15 per vehicle sold. As Geek Squad founder Robert Stephens put it, "Advertising is the tax you pay for being unremarkable." The less remarkable the product, the more the media buy has to carry ([once ROAS becomes the target](/insights/why-your-vendors-win#return-on-ad-spend-roas)).
Where we come in
We are platform agnostic, and we do not take a percentage of spend, because a fee tied to spend rewards spending whether or not it produces results. We design customer journeys across paid media, email, and other owned channels, and we measure the system on customers who buy, stay, and continue to buy, using measurement the platforms do not control. You can embed us with your team or run the work as fixed-scope, fixed-bid sprints.

- Google Ads
- Google's auction platform for search, YouTube, display, and shopping placements. Search captures people already looking for a solution, which makes it the clearest intent signal in paid media and also the easiest place to pay for buyers you already had.
- Meta Ads
- Advertising across Facebook and Instagram, bought through Meta's auction. It reaches people who were not searching for anything, so it creates demand rather than capturing it, and its reported results depend on Meta's own attribution.
- TikTok Ads
- Short-form video advertising in TikTok's feed. Performance depends on the creative more than the targeting, and winning ads tend to resemble the platform's native content more than traditional commercials.
- Programmatic Advertising
- Automated buying of display and video inventory across the open web through real-time exchanges. It offers reach beyond the walled-garden platforms, with a supply chain that takes fees at several steps between your budget and the publisher.
- Connected TV (CTV)
- Television inventory on streaming services, bought through auctions like other digital media. It brings TV reach with digital-style targeting and reporting, and its attribution is weaker than the reporting implies, because almost nobody clicks a TV screen.
- Retargeting
- Ads shown to people who already visited your site or engaged with your brand. It posts the best-looking returns in most accounts and the least incremental ones, because it reaches buyers who were already close to purchasing.
