An Introduction to Supply Side Platforms.

What Supply Side Platforms are, how they work and a list of the top Supply Side Platforms, with advantages and disadvantages of each solution listed.

Supply side platforms are tools that help publishers get the best prices for their inventory and, through real time bidding, enable them to have a steady supply of targeted ads on their sites. A supply side platform or SSP is one of the emerging technologies that more and more publishers are using to make the most of their advertising space.

While supply side platforms may be offered by companies specializing in this type of service, they are more often part of a wide range of inventory management related services. A good example of this is Admeld, which is part of Google’s Doubleclick Ad Exchange. Other companies that offer this type of platform include OpenX and Pubmatic. We’ll be exploring these services a little later, after talking about what supply platforms are and why they are so powerful.

How Supply Side Platforms Work
Online advertising has been getting both more popular and more technologically optimized in recent years. In particular, developments such as real time bidding and programmatic buying have largely automated the process of buying and selling ads. In some ways, these technologies have been more advantageous for advertisers and publishers alike. RTB, for example, makes it possible to place targeted ads directly in front of website visitors who match the demographics/behaviour and other patterns selected by the advertisers. This has allowed advertisers to purchase relevant impressions and get better returns on their investments. Publishers, also get paid better for such impressions as every impression is auctioned and sold to the highest bidder. Supply side platforms are tools that help them accomplish this. One way to understand how these platforms operate is to compare them to stock exchanges and other financial markets. When investors are ready to sell stocks or commodities, they use either a broker to negotiate the highest possible price for the shares or enter it on a terminal. This type of transaction, of course, is highly automated as brokers use software to keep track of prices and bring buyers and sellers together. In a similar fashion, supply side platforms help publishers get the best prices for their advertising space.

Main Benefits of using a Supply Side Platforms
In addition to helping publishers get as much revenue as possible for their available space, supply side platforms help make the process fast and efficient. Rather than having to seek out advertisers, publishers can rely on these platforms to do this for them. This helps them avoid having vacant space or unsold inventory on their sites. From the advertiser’s point of view, SSPs are also efficient and beneficial. Advertisers, through real time bidding, can choose how much they are willing to pay to get their ad in front of a highly targeted audience. Pricing is completely transparent, and they can often get better results than they could using traditional display advertising methods. Supply side platforms, like all types of technology related to online advertising, is getting more sophisticated all the time. They now provide thorough analytics regarding campaign yields and other vital metrics. Publishers can use this data to create content that allows them to increase their ad revenues in the future.

Some of the Leading Supply Side Platforms

Since Google is involved in every aspect of the online advertising business, Admeld is a natural choice for many publishers. Admeld is part of Google’s DoubleClick Ad Exchange – sometimes referred to as AdX. Making use of this platform certainly has its advantages for publishers. In addition to being able to tap into the Admeld supply side platform, publishers are able to work with all of the top ad networks, agencies and demand side platforms (DSPs). It’s also possible to negotiate exclusive deals with buyers at special rates.

In 2012, OpenX acquired the innovative LiftDNA supply side platform. It recently changed the name to Lift. OpenX had already been well known as a leading provider of online advertising technology, and with this addition it is better able to serve the needs of publishers. There are some unique benefits to OpenX Lift. It was the first yield optimization technology that operates from publishers’ own ad servers, giving them the maximum amount of control to manage campaigns.
