Private marketplace PMP deal types refer to specific methods used by publishers and advertisers to trade ad inventory outside of the open exchange. These arrangements allow buyers to access premium digital ad space through invitation-only auctions or fixed-price preferred deals. By moving away from the crowded open marketplace, advertisers can secure consistent access to high-quality inventory. This approach helps brands align their programmatic spending with specific audience segments while maintaining control over where their ads appear.
What are the core characteristics of PMP deals?
A private marketplace is an exclusive environment where a publisher offers inventory to a select group of advertisers. Unlike the open exchange, where any buyer can bid on any available impression, PMPs restrict access. Publishers set the rules, which often include specific floor prices or audience targeting requirements. For an advertiser, this creates a more stable supply chain. You can predict the quality of the sites your brand appears on, which reduces the risk of placement on low-relevance domains. It is a common pattern in a typical account to see higher engagement rates on PMP campaigns because the inventory is curated.
How do invitation-only auctions function?
Invitation-only auctions operate much like standard real-time bidding, but with a restricted list of bidders. The publisher grants a specific Deal ID to selected demand-side platforms or individual advertisers. When an impression becomes available, the ad server checks if the incoming bid request matches the criteria defined in the Deal ID. If it does, the auction proceeds only among the invited participants. This setup ensures that your bids compete only against a small, pre-approved group of competitors rather than the entire open market.
Why choose an invitation-only auction?
- Higher transparency regarding where ad spend is allocated.
- Ability to bid on high-performing inventory without open market competition.
- Increased control over brand safety by limiting participating buyers.
- Direct communication channels between the buyer and the publisher.
What are the benefits of preferred deals?
Preferred deals offer a fixed price for specific inventory, providing a more predictable buying experience. Unlike auctions, where the clearing price changes with every impression, a preferred deal allows an advertiser to agree on a set cost per thousand impressions (CPM) with a publisher. This is useful for budget planning, as you know exactly what you will pay for the exposure. The publisher gives the buyer first-look access to their inventory before it hits the open exchange. If the buyer decides to purchase the impression at the agreed price, the transaction occurs immediately.

How Alien Road applies PMP deal types
At Alien Road, we integrate PMP deal types into client accounts by first auditing the current reach of their open exchange campaigns. We identify domains where the brand performs well but struggles with low win rates due to high competition. We then reach out to these publishers to establish either an invitation-only auction or a preferred deal. For example, if a client is spending a significant portion of their budget on news sites, we secure a direct deal to guarantee viewability and reduce waste. Our team manages the Deal IDs within the platform, ensuring that the budgets are allocated according to the specific performance targets we have agreed upon with the client.
How to select the right deal type for your goals?
Choosing between an auction and a fixed-price deal depends on your primary objective. If your goal is to acquire high-quality traffic at scale but you are unsure of the exact value, the invitation-only auction is often the better choice. It allows you to participate in a competitive environment while keeping your reach focused on premium sites. On the other hand, if you are planning a seasonal campaign for a product launch and need to ensure 100% of your targeted inventory is secured, a preferred deal is superior. This approach removes the uncertainty of the auction process entirely.
Steps to set up a new PMP campaign
- Identify high-performing publishers from your historical report data.
- Contact the publisher representative to request a Deal ID.
- Input the provided Deal ID into your demand-side platform settings.
- Set a clear budget cap to manage spending during the testing phase.
- Review performance reports weekly to adjust floor prices if necessary.
Where to start this week
Start by pulling a domain-level performance report from your current programmatic campaigns. Look for the top 10 sites that contribute to your conversion goals but have high CPM variability. Reach out to the advertising contacts for these sites and ask about their available PMP options. Even a small test with a limited budget can provide clarity on whether these deals provide the efficiency you expect compared to your current open exchange performance.
Frequently Asked Questions
Is a PMP deal the same as a programmatic direct deal?
They are related but distinct. Programmatic direct deals usually involve a guaranteed volume of impressions, meaning the inventory is reserved specifically for the buyer. PMP deals, especially invitation-only auctions, do not always guarantee that you will win every impression. A direct deal is closer to a traditional insertion order, while PMPs are more flexible and often exist within a bidding framework.
Do I need a large budget to start using PMP deals?
Not necessarily. While some publishers have minimum spend requirements, many are open to small tests. Start by contacting publishers where your brand is already a frequent advertiser. By focusing on existing relationships, you can often negotiate lower barriers to entry, allowing you to test the effectiveness of invitation-only auctions without committing your entire quarterly budget upfront.
Can I use PMP deals for mobile app advertising?
Yes, PMP deals are fully compatible with mobile app environments. Many app developers use these deals to offer premium ad placements, such as rewarded video or interstitial slots, to trusted partners. If your target audience is heavily mobile-focused, ask your publisher partners about their mobile-specific inventory availability to ensure your Deal ID is configured correctly for those formats.
How do I measure the success of a PMP deal?
Success is measured by comparing your performance against open exchange benchmarks. Look at metrics like your win rate, effective CPM, and conversion cost. A successful PMP should provide a lower cost per acquisition or higher quality traffic compared to what you were seeing in the open market. If these metrics do not show improvement after a few weeks, consider renegotiating the price or adjusting the inventory list.
