The Advantages of Preferred Deals or Private Marketplaces for Publishers: Pros

List here some of the added benefits of running preferred deal campaigns from a publisher's point of view. Your ability to charge a premium CPM often comes at a cost for the advertiser. Thus, the long-term benefits should be mutual. 

Negotiate a Fixed CPM:

One of the biggest advantages of preferred deals for publishers is that they can negotiate a fixed rate of CPM, and after a few iterations with the buyer, the deal can continue for a long period of time. The objective is to give the advertiser the required amount of time to calculate the ROAS and negotiate a CPM rate that works perfectly well for both parties in the long run. By doing so, you not only retain your buyer, and your hard work pays off; the overall auction pressure is increased as well. 

Premium Prices:

From a monetization standpoint, preferred deals are a great bet. You can easily charge your buyers almost 2.5X or even more than your average open auction price because of the first-party data insights you're providing. It can go up to 3X if the buyer is choosing a very specific inventory and if he is buying in bulk, you can negotiate the pricing to 2X. 

Total Transparency:

Working with third-party ad networks can result in minimal transparency and ruined user experience for visitors. There are many networks that run in-banner videos in open auctions at the price of display. Things like this are uncalled for and are due to lesser transparency and interaction with the advertiser. When you're working with a direct advertiser via preferred deals, you can be assured of total transparency.   


In the long run, you can pitch your buyer with ROI-driven ad formats which are website exclusive and cannot be transacted via any exchanges. These direct deals will help you upsell your inventory and alternatively make additional room for more demands. Also, you can work directly with the advertiser in the long run to minimize network commission which is around 20-25%. 

Premium Quality Ads:

Working with direct advertisers via preferred deals have some added advantages. The delivery of the ads is premium in nature, and they are usually relevant and value-driven to your website visitors as well. An ad is supposed to be premium when the creatives are neatly designed with a clear objective, the landing page ads value the user, and the overall user experience is smooth. 

Optimized Delivery:

You will have granular control over the delivery of the ad units, like displaying one specific creative to one user, interviewing them at a fixed period of time, automatically refreshing ad units to increase the inventory, and other negotiated delivery rules. 

Seasonal Changes:

Seasonal fluctuations in CPMs can negatively impact your overall ad revenue. However, if you have a pre-negotiated fixed CPM rate, then you are sure about the revenue projections, and it gives you financial peace of mind. 


In most cases, buyers will get all the creatives approved from you. Although they are hosted on DSPs, you can take a look at the creatives and ensure the brand yet. This lets you monitor the landing pages of the ads where your website visitors will be taken once they click on an ad. The user experience is crucial, and ensuring they are not trapped by malvertising ads or ad-heavy landing pages is the responsibility of the publisher. 

The Advantages of Preferred Deals or Private Marketplaces for Advertisers

Quality drives performance and not quantity. This is one of the fundamental principles as to why preferred deals are so effective for some buyers. When you're paying a few extra dollars for impressions, you're assured to harness the following benefits of preferred deals as an advertiser.  

Brand Safety:

There is a high volume of fraud that exists in open auctions mainly because of the mixed market concept. You might end up spending thousands of dollars on a number of websites without any conversion before you finally realize the sites that are converting for you. Many of these sites may not need your brand safety guidelines, but all of these get unnoticed because it is a programmatic open auction where you have very limited control over who gets to see your ads. 


Greater flexibility in terms of contact, ad delivery, scheduling, and more is achieved when you go programmatic, preferred with a publisher. Often, the ability to make such minor changes and track them in real time can provide great insights into the effectiveness of the campaign and its overall performance. Working with a direct number of selected publishers can also lead you to AB testing. 

Higher ROAS:

One of the biggest values for the advertiser, despite paying a higher price for each impression, is a higher conversion and a better ROAS compared to the open auction. Open auction is good for finding your potential audience, but retargeting them and generating conversions and sales would happen when they see your ads on niche websites that have high-quality, relevant content. 


Invalid traffic is one of the main reasons why advertisers continue to lose billions of dollars each year. The maximum number of frauds in the open exchange despite all protective measures taken by SSPs and DSPs. Buyers tend to lose almost 10% of their budget on ad fraud and are helpless. Moving to PMPs and preferred deals save you this money, and you can have exclusive premium inventory at scale.
