Quick answer: You can advertise on HBO Max through Warner Bros. Discovery ad sales, an approved agency or a programmatic deal made available in your DSP. The practical route may be a direct insertion order, programmatic guaranteed deal, preferred deal or private marketplace. Availability varies by country, campaign size, inventory package and commercial agreement. Before planning, confirm the market, device mix, content access, deal type, creative specifications, targeting options and measurement package.
Platform note: Warner Bros. Discovery changed the service name from Max back to HBO Max in July 2025. Advertisers still search for “Max advertising,” so this guide uses that phrase for search clarity and “HBO Max” for the current platform name.
What is Max advertising?
Max advertising refers to paid placements served within the ad-supported HBO Max streaming experience. The inventory sits alongside premium series, films, documentaries, reality programming and other Warner Bros. Discovery content. Depending on the market and package, a campaign may include standard streaming video, sponsorships, interactive experiences, pause ads, contextual products or shoppable formats.
The value is not simply “television on the internet.” HBO Max is a premium connected TV environment with different buying rules from open-web video. Advertisers usually need a confirmed commercial route to the inventory, creative that meets publisher requirements and a measurement plan designed for a low-click viewing experience.
That distinction matters. A buyer should not assume that selecting connected TV in a DSP automatically provides access to HBO Max. The inventory may be available only through a specific deal, package, reseller or direct agreement. The exact route should be verified before budget is committed.
How can advertisers buy HBO Max inventory?
There are 4 common paths. The right one depends on geography, scale, required control and whether the advertiser already has DSP access.
1. Direct insertion order
A direct insertion order, or IO, is arranged with Warner Bros. Discovery or its local sales representative. It can suit large campaigns, sponsorships, custom creative, premium content alignment and guaranteed delivery. Direct buying may also provide access to formats or integrations that are not offered through a standard DSP workflow.
The trade-off is flexibility. Direct campaigns often require more lead time, defined commitments and publisher-managed execution. Ask for the minimum spend, cancellation terms, creative deadlines, delivery guarantee and reporting cadence before signing.
2. Programmatic guaranteed
A programmatic guaranteed deal combines reserved inventory with automated trafficking and reporting through a DSP. The buyer and publisher agree on volume, price, flight and targeting conditions in advance. This route can provide more predictable delivery than auction buying while keeping activation inside the buyer’s programmatic workflow.
Programmatic guaranteed is useful when a brand needs premium inventory, a defined audience or a fixed event window. It still requires deal setup, creative approval and DSP compatibility.
3. Preferred deal or private marketplace
A preferred deal or private marketplace, often called a PMP, can provide invitation-based access without a guaranteed impression commitment. The advertiser bids through an approved deal ID, usually at a negotiated or floor price.
This route offers more pacing control than a direct reservation, but delivery is not automatic. Scale can change with audience filters, geography, device settings, frequency caps, competing demand and content availability.
4. Managed agency access
An agency can assess availability, request the appropriate deal, configure the DSP, manage creative QA and combine HBO Max with other premium streaming platforms. This is often the fastest route for an advertiser that does not have the required DSP seat, publisher relationship or in-house CTV operations team.
AdGeeks starts with a platform availability assessment. We check the target market, campaign objective, planned spend, preferred DSP and inventory requirements before recommending a buying route. If HBO Max cannot meet the brief in a given market, the plan can be expanded with other premium CTV supply instead of forcing a platform-first strategy.
Can you buy HBO Max through DV360?
Potentially, but never assume universal access. Display & Video 360 supports publisher packages, private deals, preferred deals and programmatic guaranteed inventory through its Marketplace and My Inventory workflows. Whether a specific HBO Max deal is visible to a given advertiser depends on market, seller configuration, account permissions and the active commercial agreement.
The correct workflow is to search the DV360 Marketplace, ask the seller or agency for the exact deal path, and validate the deal inside the intended partner account. Confirm the publisher name, exchange, geography, device eligibility, creative duration, floor or fixed CPM, forecast and reporting fields. A screenshot from another account or market is not proof that the same inventory is available to you.
If your team needs access or managed execution, review the AdGeeks DV360 service and the DV360 access guide.
What ad formats are available on HBO Max?
Format availability changes by market and sales package. Treat the following as a planning menu, then confirm what is live for your campaign.
Standard streaming video
Pre-roll and mid-roll video are the core formats for most CTV plans. These ads usually use broadcast-quality video with fixed durations such as 15 or 30 seconds. Exact duration, file type, bitrate, audio and safe-area requirements come from the publisher or deal specification.
Pause ads
Pause ads appear after the viewer pauses content. They create a non-interruptive moment for a static or enhanced brand message. Warner Bros. Discovery has also introduced shoppable pause experiences that can connect the television screen to a mobile action.
Interactive video
Interactive formats can let viewers reveal content, browse products, request information or move into a branded experience. Interaction mechanics depend on the device and product. A remote-control experience on a connected TV is not the same as a clickable mobile ad, so the creative concept must work across the eligible screen mix.
Shoppable formats
Shop with Max connects content context to product discovery. Warner Bros. Discovery has described product showcase ads that use QR codes and a mobile shopping experience. These formats can reduce the gap between viewing and action, but they require compatible product feeds, landing experiences and attribution.
Contextual Moments
Moments uses visual, audio and contextual signals to align ads with themes, sentiment and on-screen elements. WBD has expanded the product toward scene-level and emotion-based targeting. This can help brands move beyond broad genre targeting, but the available categories and eligible titles vary.
Sponsorships and reduced-ad experiences
Title sponsorships, collection partnerships, InFront and Brand Block products can give a brand greater share of voice around selected content. Some products reduce the number of interruptions or let one sponsor own a viewing experience. These are usually planned directly or through a custom agreement.
For the broader technical checklist, use the CTV ad specifications guide and confirm the final publisher spec before export.
What targeting options should you expect?
HBO Max targeting can include a mix of publisher data, deal-level controls and DSP targeting. The exact combination depends on the buying route.
Geography: country, region, city or other eligible location level.
Audience: demographic, behavioral, interest or first-party audience segments where supported.
Content: genre, title, collection, theme, contextual moment or sponsorship environment.
Device: connected TV, mobile or other supported streaming devices.
Time: daypart, flight dates and event windows.
Frequency: exposure controls within the publisher, deal or DSP environment.
More filters do not always create a better campaign. Premium streaming inventory can become too narrow when small geographies, short flights, detailed audience segments and strict frequency caps are layered together. Forecast the final combination, not each filter separately.

Creative requirements and QA
Start with the exact creative specification attached to the deal. Do not rely on a generic CTV export preset.
Confirm duration. Check whether the deal accepts 6, 15, 30 or other approved lengths.
Match the technical spec. Validate resolution, aspect ratio, codec, bitrate, frame rate, audio and file size.
Design for television. Use large type, clear branding, strong contrast and TV-safe placement.
Make the CTA screen-appropriate. Use a QR code or memorable next step when supported. Do not depend on a mouse click.
Prepare variants. Test different openings, offers or messages while keeping the brand recognizable.
Allow time for review. Publisher approval can delay launch if the file, claims or landing experience do not meet policy.
Run a device-level preview when possible. A creative that looks clean on a laptop can fail on a large television because the text is too small, the QR code is unreadable or the first seconds do not establish the brand.
How should Max advertising be measured?
Measurement should start with the business objective, not the platform dashboard. CTV produces fewer direct clicks than desktop or mobile media, so last-click attribution alone will miss much of the effect.
Delivery and quality
Impressions and completed views
Video completion rate
Reach and average frequency
On-target delivery
Invalid traffic and brand suitability signals where available
Brand outcomes
Awareness, consideration and purchase-intent lift
Branded search or direct-traffic change
Survey-based brand lift
Incremental reach beyond linear TV or other streaming platforms
Business outcomes
Site visits or engaged sessions after exposure
Qualified leads, sign-ups or purchases
Store visits or sales matchback where supported
Incremental conversions or revenue versus a control
Warner Bros. Discovery announced an Always-On Measurement & Attribution Dashboard in 2026 with in-flight visibility across streaming, digital and linear campaigns. Availability and partner integrations should still be confirmed for the specific buy. Independent measurement can also be layered in when the campaign has enough scale.
Define the source of truth before launch. Record the attribution window, identity method, deduplication rules, control design and minimum sample requirements. This prevents a post-campaign debate between publisher reporting, DSP reporting, analytics and sales data.
Use the AdGeeks reach and frequency planner to pressure-test the media plan before launch.
A practical Max advertising launch checklist
Define the job. Decide whether HBO Max is being used for awareness, incremental reach, consideration or a measurable business outcome.
Confirm the market. Check that the ad-supported service and required product are active in the target country.
Verify the buying route. Select direct IO, programmatic guaranteed, preferred deal, PMP or managed agency access.
Request a forecast. Use the real geography, dates, audience, device mix, frequency cap and creative duration.
Review the deal. Validate seller, exchange, CPM, commitment, eligible inventory and cancellation terms.
Build the media mix. Compare HBO Max with other premium streaming supply instead of planning it in isolation.
Prepare and approve creative. Export to the confirmed spec and complete publisher QA early.
Set measurement before launch. Document KPIs, attribution, lift studies, reporting cadence and data ownership.
Monitor delivery. Watch pacing, reach, frequency, completion rate, audience scale and creative performance.
Report outcomes. Connect exposure and quality metrics to brand or business results.
How AdGeeks approaches HBO Max planning
AdGeeks treats HBO Max as one part of the media plan, not as a checkbox. We first assess whether the inventory is available in the required market and buying account. Then we compare the direct and programmatic routes, model reach and frequency, check creative requirements and build an outcome-reporting plan.
The result is a clear recommendation: buy HBO Max through the verified route, combine it with other premium CTV platforms, or move budget elsewhere if the inventory cannot support the objective. That keeps the plan tied to audience and outcomes rather than platform name alone.
Frequently asked questions
Can small and mid-market brands advertise on HBO Max?
Yes, if a suitable buying route and inventory package are available. Minimums vary by market, seller, deal type and campaign design. An agency or publisher representative can confirm the current threshold and forecast before the brand commits budget.
Is HBO Max inventory available in the open auction?
Do not assume it is. Premium streaming inventory is often sold through direct agreements, programmatic guaranteed deals, preferred deals or private marketplaces. Confirm the seller, exchange and deal ID inside your DSP.
Can I target specific HBO Max shows?
Sometimes. Title sponsorships, collections, contextual products and selected packages can support content alignment. Exact title availability and targeting granularity vary, and some packages are sold only through direct or custom agreements.
What creative length should I use?
15-second and 30-second assets are common in streaming TV, but the deal specification is the authority. Confirm accepted durations and technical requirements before producing or adapting creative.
How do I measure conversions from HBO Max ads?
Use a combination of exposure reporting, site or sales outcomes, attribution partners and incrementality testing where scale allows. Avoid judging a CTV campaign only on direct clicks or last-click conversions.
Should HBO Max run as a standalone campaign?
Usually not. Most brands benefit from comparing HBO Max with other premium CTV inventory and managing reach, frequency, creative and measurement across the full streaming plan.
