Marketer’s guide to Private Marketplace

PMP (private marketplace) is basically a way of buying inventory via programmatic. In other words, audience buying by an automated process where the advertiser gets value due to reachability, top-drawer service or premium placement.  Audience buying is determined by analyzing behavioral data, location data and device data which aids in targeting a specific group of audience. A private marketplace is an invite only exchange that allows publishers to whitelist specific advertisers based on mutual interests, reserve an inventory for them at relatively high valuation.

If premium is defined as well targeted, less crowded inventory, premium programmatic is a means of automating much of the ad exchange process, allowing advertisers to purchase impressions in real time (RTB, real time bidding) while maintaining the high cost and edge of premium inventory.

Factors that make PMP advatageous are

  •  PMPs can offer less competition for the advertisers as the inventory is usually open for premium clientele
  •  Helps reaching out to a targeted audience
  • Targeted ads lead to higher conversions even if the CPM is high in some cases. It is however, essential to understand the pricing models – CPC, CPA, CPL etc. that maybe more appropriate in certain cases, based on the campaign type

To establish the automated buy/sell process in real time, a unique Deal ID takes care of the required correspondence between publisher and advertiser in order to replace the traditional IO (insertion order). The deal id allows an advertiser to recognize the seller/publisher and the accompaying pre-decided agreements that come with it and vice versa, in a real time automated exchange. The moment a user visits a site,the publisher sends a bid request to the ad exchange, after having determined the user’s location, online behaviour, previous browsing history and device. The advertisers bid on impressions and the highest bidder wins the impression. The deal id is the parameter being sent into bid requests and recieved from the bidders, which is then sent ahead to the DSP (Demand side platform). Deal IDs are very important from a measurement point of view, both for publishers and advertisers to measure the effectivenesss of inventories, campaigns, impressions and conversions.

Thus, the rise of PMP has lead to the media planners taking on more of an analyst role, analyzing data to find the source of traffic, understanding the ad tech eco system and geting innovative with the latest tools and products like native advertising, content sponsorship and targeted audience buying. Ultimately private marketplaces work the same way as traditional open exchanges, both requiring to evolve with time and technology!
