How to Choose the Right Ad Server (Plus Top 10 Ad Servers Reviewed)

It’s a well-known fact that monetizing your content effectively requires more than simply running ads. Campaigns, as well as individual placements, must be managed, edited, and repeatedly tested for performance. Ad servers can help you do exactly that via a centralized platform.

An ad server is a tech platform that hosts advertisements and delivers them to publishers to be displayed across one or more formats. Many provide their users with comprehensive reporting on campaign analytics and tools to help track ad performance and better target audiences. Getting the most out of your ad server experience depends on choosing the right product or service to suit your needs. The first step is understanding what exactly is being offered, and for whom.

Welcome to the Party, Pal

Ad servers can generally be divided into two categories: first- and third-party ad servers. Ad industry professionals are likely well aware of the differences, but it’s important for those not working in ad ops to understand the breakdown.

First-Party Ad Servers Third-Party Ad Servers
Used by a publisher’s ad ops department to manage an advertiser’s campaigns on the publisher’s own website. Used by advertisers and agencies to store and manage ad codes, and to deliver, track, and interpret the results of ad campaigns shown on publishers’ websites.
Simplifies the process of managing ads and allows publishers to directly sell ad slots to advertisers. Verifies certain metrics (e.g. impressions and clicks) from campaign data provided by publishers.
Decides which creative assets (from an ad network or third-party ad server) should be displayed in an ad slot based on audience targeting data if no direct campaigns are being run. Optimizes creative by testing various ads used in a campaign. (Targeting and ad tags are still loaded by first-party ad servers.)

As the market shifts toward programmatic and real-time bidding (RTB), and the need to serve dynamic ads across multiple screens, a great deal of technology options are now available to digital publishers and advertisers. As ad-tech companies on the buy and sell side seek to broaden their ad serving capacity to encompass both sides of the digital media market, and demand-side platforms (DSPs) and supply-side platforms (SSPs) continue to expand in their delivery of real-time biddable ad impressions, it begs the question: do publishers and advertisers still benefit from separate servers? So let’s discuss it.

Do Publishers and Advertisers Need Different Ad Servers?

In short: yes. Thanks for reading our blog post!

But in all seriousness, publishers and advertisers have fundamentally different, complex ad serving needs, and that’s unlikely to change in the foreseeable future.

Publishers, for example, require advanced control over ad inventory, targeting, and campaign pacing, and they need tools to optimize creative delivery across multiple connected devices. They also need to be able to access detailed reporting information and create inventory forecasts, usually on a highly granular level.

Furthermore, with the push towards substantial automation, need the ability to divide inventory by cost, content, and audience.

Advertisers, on the other hand, face a set of challenges that are mostly centered on creative and campaign performance measurements. They rely on buy-side ad servers for efficiency in the deployment and reporting of each ad unit, as well as for attribution and performance tracking, which helps advertisers with optimizing media and creative.

At some point in the near future, different services may connect to support both buy and sell-side companies in a cross-channel RTB environment. But currently RTB is still a relatively new phenomenon and its impact on the landscape is still being felt.

Right now, SSPs and DSPs have limited functionality when compared to independent ad servers, and they don’t always meet the specific needs of their users. They offer a top-down view of data that doesn’t necessarily consider scale or prediction. Often, professionals find themselves using both an ad server and a DSP or SSP to get a full view of their campaign.

Hosted and Self-Hosted Ad Servers

Now that we’ve established why having an independent ad server is a commodity, it’s time to start getting into specifics. Beside first-and third-party platforms, ad servers further break down into hosted and self-hosted types:

A hosted ad server is one which is maintained and run by an ad server company.

A self-hosted platform is installed and maintained by the user.

There are pros and cons to both types of server that must be weighed against your own ad serving needs and the specific strengths and talents of your team. Take a look at the following chart to figure out which is right for you.

Hosted ServersSelf-Hosted Servers
  • Easy to use without advanced technical knowledge.
  • Requires no installation.
  • Provides a high level of user support.
  • Automatically updated.
  • Closely monitored by provider to ensure speed and reliability.
  • A self-hosted script can by fully customized across the front- and back-end according to your needs.
  • The script is offered at low one-time fee or in some cases, at no cost.
  • Total data control and awareness.
  • Comes with a price tag that can run high.
  • Limited customization.
  • Low data control, as your data is stored by a third party.
  • Requires technical knowledge to install.
  • Updates must be sought out.
  • You must handle your own server maintenance.

Now that we’ve reviewed all there is to know about ad servers, it’s time to delve into some of the most popular options on the market.

However, despite the technical learning curve, user reviews indicate a high degree of satisfaction with the offerings the script provides.

Cost: Along with being free to download, Revive also does not charge fees for ad delivery; a user’s only cost derives from their domain name and server hosting. That being said, it is worth noting that Revive’s script is huge and uses a great deal of server resources – users must meet certain technical requirements for it to run. Trying to use Revive’s script without dedicating enough server space to its use can result in lagging load time on sites displaying ads.

Users also get access to OIO Marketplace, an ad marketplace to sell unsold ad space.

This script allows users to run third-party ad networks alongside their own ads, and a single license covers all the user’s websites. OIO offers forum and email customer support, so users will need to be able to solve most of their issues independently.

Cost: OIO Publisher is available for $47.

Who It’s For: OIO Publisher is best for independent, technically literate users who need a basic ad server that lets them maximize their ad revenue.

In Conclusion

Choosing the right platform starts with an understanding of your business’ needs, where you sit in the market, and how an ad server can serve you (pun entirely intended). Small businesses will necessarily have different financial, service, support requirements than a large company that has access to a large pool of resources. Advertisers and publishers with a highly localized audience will not need the scalability or regulatory compliance an international business does.

Make sure you also consider others on your team and understand how their perspectives play into the tech stack you build for yourself. A highly independent and technically skilled ad ops team will have completely different priorities and need for support structure than a creatively inclined team of marketers. And of course those who work independently will need the ability to do it all, from creative to operations.
