Key Points

  • Today, ad exchanges exist primarily within other tools rather than as a standalone entity.
  • Some of the top tools that have the functionality of ad exchanges include Google AdX, Xandr, OpenX, Magnite, PubMatic, and Index Exchange.
  • When you work with Playwire, you get all the functionality of the best ad exchanges and a litany of other tools in your ad tech stack covered.

Ad exchanges, which today are incorporated into other tools like Supply Side Platforms (SSPs) or ad servers, are a good idea for publishers who are interested in increasing their ad revenue. That's especially true when you compare them to alternatives like ad networks or simply letting bid requests go unfilled. But which exchanges are the best ad exchanges for publishers?

The answer to that question, of course, will depend heavily on your unique needs. However, we can say with relative certainty that the ad exchanges discussed below are among the best in the business for publishers. Read on to learn more.

The Most Important Features of the Best Ad Exchanges

Before we get into the list of the best ad exchanges for publishers, let's explore what makes a tool's ad exchange abilities "the best" in the first place. In general, you want to look for the following features in any tool that includes an ad exchange:

  • A large network of advertisers and agencies
  • The ability to control price floors and other aspects of programmatic auctions
  • A publisher-friendly user interface
  • Support for high-value, high-CPM ads, including custom and video ad units
  • A demonstrated history of high CPMs for publishers using the network

The 7 Best Ad Exchange Tools

These seven tools do a good job of meeting all of the criteria described above. In our view, they provide the best ad exchanges for publishers in 2022; however, it's important to keep in mind that these tools are not standalone ad exchanges. Most of them are SSPs that offer an ad exchange. In any case, these are the seven leading the pack:

1. Google's Ad Exchange

Google has its hand in everything related to the internet advertising space, and ad exchanges are no exception. Google has built an ad exchange called Google AdX, formerly known as DoubleClick Ad Exchange,  that it offers as part of its Google Ad Manager (GAM) services.

Publisher Benefits:

AdX is a Google product, so it gives publishers access to some of the broadest demand available anywhere. Think about it like this: Everyone, including advertisers and agencies, thinks of Google ads when they think of internet or digital advertising issues, so you're leaving ad revenue on the table if you're not capitalizing on Google's broad reach.

AdX Reviews:

GAM had garnered 4.1 stars on G2 and 8.7 out of 10 on TrustRadius as of the time of publication. Some of the benefits reviewers highlighted included the broad demand and intuitive features like a copy function that allows you to recreate an ad campaign quickly. On the negative side, reviewers mentioned occasional crashing and latency.

2. Xandr

Like many of the best ad exchanges that made it onto this list, Xandr is typically categorized as an SSP and is the result of several mergers and acquisitions over the years - most notably the acquisition of AppNexus. Potential ad tech monopolies notwithstanding, these types of companies tend to amass quite a bit of demand through an enormous ad network, and that is certainly true for Xandr. 

Publisher Benefits:

Xandr offers most of the expected ad exchange features and benefits, such as broad demand, customization options, and solid CPMs, but it also offers a lot more to publishers who are just starting to put their ad tech stack together. Xandr is also an ad server, a demand side platform (DSP), and more.

Xandr Reviews:

As of the time of publication, Xandr had a 7.3 on TrustRadius and 3.7 stars on G2. Many negative reviews cited a confusing and sometimes clunky user interface, while positive reviews enjoyed the tool's ability to integrate with various other tools, including DSPs.

3. OpenX

OpenX, another solution typically categorized as an SSP, is a big name in the ad exchange business, and that is a big part of the reason why this exchange has amassed more than 100,000 advertisers and processes more than 200 billion ad requests per day.

Publisher Benefits:

Demand of this magnitude is hard to come by outside of Google's sphere of influence, meaning one of the biggest publisher benefits of working with this ad exchange is access to nearly unparalleled levels of demand for your digital ad inventory. On top of that, OpenX remains fully certified by the Trustworthy Accountability Group (TAG).

OpenX Reviews:

With a 6.8 on TrustRadius and 3.2 stars on G2, OpenX is fairly middle-of-the-road in terms of the best ad exchanges. (Few ad exchanges have consistently high reviews across all popular review sites.) Happy users reported that this tool works with publishers of all sizes and maintains strong reporting functionality. Unhappy reviewers mentioned a lack of scale in the sale of video ads and lower CPMs for some publisher ad inventory types.

4. Magnite

Once known as the Rubicon Project, Magnite is a giant in most things ad tech, including ad exchanges. Magnite's ad exchange began as a supply-side platform (SSP) and followed the natural evolution of many SSPs: building a huge network of publishers and their ad impressions, realizing the potential to profit by connecting those publishers directly with buyers, and doing so.

Publisher Benefits:

Magnite has invested heavily in connected TV (CTV) and over-the-top (OTT) channels, meaning this is an ideal ad exchange for publishers who operate on these channels. This ad exchange platform also offers a readymade header bidding solution (built off of Prebid), so publishers who are open to multi-channel revenue increases may find Magnite particularly beneficial.

Magnite Reviews:

G2 reviewers gave Magnite 3.2 stars on average, while TrustRadius reviewers rated it 9.8 on average. On the plus side, reviewers liked the global presence Magnite has built, as well as the user-friendly interface. On the negative side, reviewers mentioned low fill rates.

5. PubMatic

PubMatic is a household name among ad tech professionals, and there's a reason for that. This company has innovated in all kinds of spaces for a long time, and its ad exchange perfectly reflects that. 

Publisher Benefits:

PubMatic goes heavy on ad quality and cutting-edge technologies built around real time bidding (RTB), which is the tech that powers most ad exchanges. But the platform goes a step further with well-developed private marketplaces (PMPs) that facilitate better ad quality and higher CPMs.

PubMatic Reviews:

With 3.2 stars on G2 and a 7 on TrustRadius, you might not be able to immediately tell that this is one of the best ad exchanges for publishers, but you can see the positives in the reviews. Reviewers mentioned a crystal-clear user interface and high CPMs. Some negative reviews did highlight having trouble getting in touch with customer service, though.

6. Index Exchange

Index Exchange is one of the tools that has remained most dedicated to its ad exchange offering over time. That has translated into a focused offering that works really well for publishers who already have their other ad tech bases covered.

Publisher Benefits:

This tool puts exchange quality front and center, meaning you may not have to go with a private ad exchange or preferred marketplace to ensure high quality if you choose Index Exchange. The tool has also put in the work to facilitate the buying and selling of any kind of ad format, including banner ads, video ads, connected TV (CTV) ads, native ads, and similar.

Index Exchange Reviews:

Despite being a relatively well-known ad exchange within the digital advertising space, Index Exchange had not made the rounds in the online reviews circuit as of the time of publication. Anecdotally, however, this exchange is easily among the best ad exchanges for publishers.
