    Pros
    OpenX
    • OpenX is a system that was designed to scale as is evident in some key design decisions found throughout the platform. The multi-server setup that was chosen at Mail.com allowed for a distributed server architecture which separated the front end web delivery nodes from the backend MySQL Database master which replicated data back to each front end delivery node mysql slave. This eased the ability to horizontally scale as needed due to the ingenious separation of the ad impressions data tables on the delivery nodes which were being collected locally on each ad impression and then processed periodically back to to the master database which replicated the aggregated statistics back to the delivery nodes. The ability to load balance across the front end web delivery nodes, add caching at many different layers, utilize a CDN for the static ad images, implement PHP accelerators, and hit memcached instead of the MySQL master made the OpenX platform a service that was very resilient to failures.
    • The ability to optimize the platform is also something that OpenX does very well. This is evident in many of the config key parameters available. In addition to OpenX specific tunable's, optimizations can be made at many different levels in which the system sits. These include hardware and operating system level optimizations, tcp and networking stack optimizations, web server/php-cgi configurations, and database (MySQL InnoDB) tunable's. There are many different optimization knobs that can be tuned to help scale the application for the best performance possible
    • The documentation was simple, to the point, and well written which led to an easy initial implementation and roll out of a multi-server setup. The installation and upgrade procedures were straight forward even for the complexities of the multi-server setup. I also found the OpenX team to be accessible and even got a chance to meet some of the team at their Up Close and Personal events at Cal Tech in Pasadena. Core developers were on hand to answer technical questions and also made themselves available to us via email and irq channels.
    • The open nature of the OpenX platform allows for flexibility in the choice of web serving platform to use (Apache, nginx, Lighttpd) and also the database management systems (MySQL, PostGreSQL)

    Cons
    OpenX
    • Propagation could be improved; ad units that need to go live immediately could take up to 45 minutes to propagate.
    • Over-complexity can be confusing. There are multiple tiers before assigning ad units per order and it seems unnecessary.
    • Real-time reporting or a status dashboard would be great.

    • Sometimes I find it takes time to find exactly where a certain analysis I had looked at previously is when I go to replicated. Website could be streamlined that way.
    • You can only compare 5 companies at a time on the website but often I'd like to compare more. You can always download the data to compare two different searches, but that adds time.

    I no longer work at the company where I was using OpenX, but if I were then I'd certainly stay aboard. Frankly, there are a lot of sunk costs involved with building all of the infrastructure we had put in place, the system was working very well even if reporting was a hassle, and our team was trained on it. Also, I'm not aware of another product that does everything else we'd need it to.

    Usability
    OpenX
    I was given the system to use as part of setting up a whole new site from scratch in less than 2 months, with a large number of specialty hub pages to run ads on and lots of content I needed to run disease specific ads on. The system was easy for me to learn on the fly in a very compressed time frame. I would have loved more chance to really dig in under the hood to see all that it could do, but given how fast I had to work, I got everything up and running and looking great. And I did it ahead of my launch deadline too. My only reservation might be for people who are not as patient as I am in picking things up, or as hands on. Customer service was great if I needed them, and a quick start guide with the essentials would be ideal for those people.

    Similarweb is a very easy to use tool and gives us data on the go. It takes only a few clicks to get the relevant data. However, I have deducted 2 points as it only allows us to add 5 websites at a time on the platform, and data availability is only for the last 37 months.

    OpenX
    They went above and beyond without ever asking for additional money and we met our launch date and immediately started to meet and even surpass our business goals. Nothing was too much trouble, which really stood out compared to other companies I had and was at that time also working with. Customer service can really make or break any business; if i expect my staff to give good customer service, I expect to get it too, and Open X gave it.

    Support is just helpful and effective when you need them; we have only needed to contact them once about a misunderstanding while setting up our Market Analysis. Since we don't really contact them too often, it's hard to offer anything but a positive rating from the single positive experience we had with tech support.

    OpenX is less focused than MoPub and it has a bigger reach as it is not limited to the mobile app. Unlike MoPub that focuses on performance, OpenX comes from the branding world and is pushing into CTV and other areas of the industry more catered to traditional media agencies and not pure ad tech players.

    Whilst data.ai has strong app competitor intelligence data, Similarweb do a better job of showing the upstream and downstair behaviour across desktop and mobile web. Additionally, Similarweb's channel marketing mix goes deeper and allows us to understand a wider set of channels and be able to get a holistic understanding of our overall marketing strategy performance

    • OpenX made it easy to manage online advertising. At the time I used the product I was the lead developer in charge of implementing the solution but quickly was put into the role of managing the traffic and training other users. It was really easy for a technical user to become a traffic manager. Getting other users trained and up to speed was very efficient.
