What is Direct Buy?
Also known as: Direct media buy, Insertion order buying
What is a direct buy?
A direct buy is ad inventory bought straight from a publisher through a negotiated contract, not an open auction. The buyer agrees on price, placement, flight dates, impression volume, and creative specs before a single ad serves. Per the IAB Tech Lab Programmatic Supply Chain primer, direct and programmatic-guaranteed deals still represent a meaningful slice of US digital display spend in 2024.
The defining feature is the one-to-one relationship. The advertiser knows exactly which site, app, or channel will run the ad. The publisher knows exactly who is buying and at what price. There is no real-time bidding, no spray-and-pray, no anonymous supply.
A direct buy answers three questions an open auction cannot:
- Will my ad sit next to brand-safe editorial?
- Can I lock a homepage takeover for launch day?
- Will I get a custom format the DSP cannot serve?
[CITATION CAPSULE] A direct buy is the rented placement done by handshake. The advertiser and publisher sign an insertion order that locks price, dates, volume, and specs. Per the IAB Tech Lab, direct and guaranteed deals still anchor premium inventory in 2024 even as programmatic takes the bulk of paid media spend.
Direct buy vs programmatic
The two models solve different problems. Direct buys win on premium and custom. Programmatic wins on scale and targeting. Per eMarketer's 2024 programmatic forecast, 91.3 percent of US digital display ad spend ran programmatically in 2024, leaving direct deals to fight for the remaining premium tier.
| Dimension | Direct buy | Programmatic |
|---|---|---|
| Buying method | Negotiated IO | Real-time auction via DSP |
| Inventory | One publisher, named placements | Many publishers across exchanges |
| Pricing | Fixed CPM, locked upfront | Variable, second-price or first-price auction |
| Targeting | Site context, publisher first-party data | Audience signals, third-party data, retargeting |
| Setup time | Days to weeks | Minutes to hours |
| Minimum spend | Usually $5,000 to $50,000+ | None on most DSPs |
| Reporting | Publisher report plus advertiser ad server | Unified DSP dashboard |
| Best for | Brand sponsorships, premium context, custom units | Scale, performance, retargeting |
The decision is rarely either-or. Most modern plans run both. Direct for the high-impact moments. Programmatic for the always-on volume.
How direct buys work
A direct buy moves through four stages. Each one has a paper trail and a deadline.
1. RFP (request for proposal)
The buyer sends an RFP to one or more publishers. The brief lists campaign goals, target audience, flight dates, budget range, and required formats. The publisher comes back with a media plan inside three to five business days. The plan names placements, CPMs, projected impressions, and any custom unit costs.
2. Insertion order (IO)
Once the buyer picks a plan, both sides sign an insertion order. The IO is the binding contract. It specifies the price, the flight, the impression goal, the placement, the creative specs, and the cancellation window. Most US deals reference the IAB and 4As Standard Terms and Conditions for Internet Advertising, version 3.0 as the legal baseline.
3. Ad ops trafficking
The advertiser's ad ops team builds the creative tags in an ad server, usually Google Ad Manager or Flashtalking. Tags ship to the publisher with the IO reference number. The publisher loads them into their own ad server and tests rendering. Both sides sign off before the campaign goes live.
4. Reporting and reconciliation
After launch, both sides pull impression and click numbers. The publisher reports from their ad server. The advertiser reports from theirs. Discrepancies under 10 percent are common and tolerated. Bigger gaps trigger a make-good, where the publisher serves extra impressions to close the difference at no charge.
When direct buys still make sense
Direct buying did not die when programmatic took over. It moved up-market. Three use cases keep direct buys relevant in 2026.
Premium inventory. Homepage takeovers on the New York Times, masthead spots on YouTube, opening sponsorships on top podcasts. None of that inventory clears the open exchange. It sells direct or not at all. CPMs run $25 to $100 but the audience and the context come with it.
Custom integrations. A branded content series, a co-produced video, a sponsored newsletter, a custom interactive unit. These are not standard IAB sizes. They get briefed, designed, and signed off in a direct conversation. Per AdExchanger's 2024 reporting on creator deals, custom and branded content spend keeps growing even as programmatic display flattens.
Sponsorships and tentpoles. Award shows, sports broadcasts, product launches, holiday tentpoles. Buyers want guaranteed placement on a fixed date. The auction cannot promise that. A direct buy with a make-good clause can.
[UNIQUE INSIGHT] The fastest-growing direct buy category in 2026 is not display. It is podcast host reads and creator integrations. Both formats sit outside programmatic supply because the inventory is the host's voice, not a banner slot. The buying motion looks like 2008 magazine sales. Email, RFP, IO, payment, run.
Common direct buy pitfalls
Direct buys carry friction programmatic does not. Most fail in the same three places.
- Discrepancy fights. Publisher reports 1.2 million impressions. The advertiser's ad server reports 1.05 million. The 12.5 percent gap eats the make-good budget and the analyst's afternoon. Tighten by serving the same pixel from both sides and agreeing on which counter wins before the campaign launches.
- Creative misses the spec. The IO calls for a 970x250 unit at 150 KB. The agency ships a 200 KB file. The publisher rejects it 24 hours before launch. Build a spec checklist into the IO sign-off.
- No frequency cap across publishers. Buying direct on five sites without a unified frequency cap means the same user sees the ad 40 times. Run the direct buys through the same ad server with a global cap, or accept the waste.
Real-world example with numbers
A premium skincare brand wants to launch a $250,000 holiday campaign. The team splits the budget.
The plan:
- $100,000 direct buy with a beauty publisher: homepage takeover, custom video unit, two newsletter sends. Flat CPM $35.
- $80,000 direct buy across three top beauty creators: Instagram Reel plus YouTube integration. Flat fee, not CPM.
- $70,000 programmatic-guaranteed deal on CTV via a DSP: $45 CPM, beauty-content adjacency only.
The result over four weeks:
| Line | Spend | Delivered impressions | CPM | Role |
|---|---|---|---|---|
| Beauty publisher direct | $100,000 | 2.86M | $35.00 | Premium context, brand lift |
| Creator integrations | $80,000 | 4.10M (organic plus paid) | $19.50 blended | Trust, social proof |
| CTV programmatic-guaranteed | $70,000 | 1.55M | $45.00 | Reach against beauty viewers |
| Blended | $250,000 | 8.51M | $29.38 |
A holdout study run by the brand's measurement partner showed a 22 percent lift in unaided brand recall and a 9 percent lift in branded search during the flight. Click-attribution alone would have written off the direct buys as expensive. The lift study paid for them.
Direct buy in 2026 (the return-of-direct trend in CTV)
Two trends pulled direct buying back onto the media plan in 2026. Both center on connected TV.
CTV inventory shortage on the high end. Per eMarketer's 2024 CTV forecast, US CTV ad spend reached $33.35 billion in 2024 and is projected past $40 billion in 2026. Premium ad-supported tiers on Netflix, Disney+, Amazon Prime Video, and Max sell a meaningful share of inventory through direct and programmatic-guaranteed deals. The auction tier on those platforms exists, but the most desirable spots get held back for direct buyers willing to commit upfront.
Brand safety pressure. After several years of made-for-advertising sites and AI-generated junk inventory polluting open exchanges, big advertisers have moved budget back toward known publishers. AdExchanger's 2024 coverage of the made-for-advertising debate documented major brands cutting 15 to 30 percent of their open-web programmatic spend and redirecting it into direct deals and curated marketplaces.
The net effect: direct buying did not fade. It became the premium tier of a two-tier market. Programmatic carries the volume. Direct carries the brands that pay attention to where their ads land.
A modern media buyer runs both motions in the same week. RFPs in the morning. DSP optimizations in the afternoon. The IO and the bid request live side by side on the same campaign sheet.

Frequently asked questions
What is the difference between a direct buy and programmatic advertising?
A direct buy is negotiated one-to-one with a publisher and locked in writing through an insertion order. Programmatic uses automated auctions across many publishers via a DSP. Per the IAB Tech Lab, direct deals still account for roughly 20 percent of US digital display revenue in 2024, with the rest running through programmatic pipes.
Is a direct buy more expensive than programmatic?
Usually yes on a CPM basis. Direct buys on premium publishers run $15 to $40 CPM. Programmatic on the open exchange runs $1 to $8. The premium pays for guaranteed placement, fraud-free inventory, and editorial context that auction buying rarely delivers.
What is an insertion order (IO)?
An insertion order is the contract between an advertiser and a publisher for a direct buy. It locks the price, flight dates, impression volume, placement, creative specs, and cancellation terms. Most agencies still use the IAB and 4As Standard Terms and Conditions for Internet Advertising, version 3.0, as the legal baseline.
Are direct buys still relevant in 2026?
Yes, especially in connected TV. Per eMarketer, US CTV ad spend reached $33.35 billion in 2024 and a meaningful share runs as direct or programmatic-guaranteed deals. Brands also return to direct for sponsorships, podcast host reads, and brand-safe placements where auction inventory carries reputational risk.
Who handles a direct buy on the buyer side?
A media buyer or planner runs the negotiation. An ad operations team traffics the creative through an ad server like Google Ad Manager. Reporting falls to the analytics team, who reconcile publisher numbers against the advertiser's own ad server. On smaller teams one person wears all three hats.
