    I have found Google Tag Manager as the go to solution for managing all of your event and conversion tags for your website. Not only does it make it easy to manage all of your tags in the one place, it is fairly intuitive to use and there is plenty of videos and help documentation online to help set up what ever you need. No scenarios come to mind at the moment on where it is less appropriate to use.

    What are the best ways to integrate it with salesforce.com? What are the best ways to target our users with this tool? To segment the users? How can I integrate my ads with your adexchange-what sizes are you looking for in terms of banners, skyscrapers and so on. In this way I can plan my in house ad and those for the exchange to be the same size, to avoid duplication of work.

    Pros
    Google
    • Selecting elements on a site [object, class, cookie, etc] (to later fire an event, send some data, etc) is very easy with triggers. Want to add an event when someone clicks on a button? Super easy. It was many many DOM selectors and you can even add custom functions if you need to do something more specific
    • In general, firing events in different circumstances is very easy mixing triggers and tags. You can track almost any element of the DOM and do whatever you want with it.
    • Testing is a great functionality. Only you can see what's on the site and you can debug it easily by seeing which events or tags were triggered and all the DOM elements involved (and why they matched the trigger).
    • Working in environments (staging, production) and versioning is easy to do, deploying changes in 2 clicks.

    • 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
    Google
    • There are several good integrations, but there can always be more. Native tracking for call tracking solutions, analytics providers, non-Google advertisers would be top of my list.
    • Documentation is just dreadful. Luckily there are some awesome folks out there doing crowdsourced tutorials (shout out to Simo Ahava) but by and large the Google Tag Manager instructions are worth what you pay for them.

    • 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.

    I haven't found another option for us to use especially one that is free. Down the road we may go a different route but for now GTM is a good option and does what we need it to do. It'd be nice to get more support or more integrations but with the free version there's only so much one can expect to get I suppose.

    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.

    No difficult obstacle to overcome but Google Tag Manager can still be difficult for many users to deploy. Sure the basic HTML script can be deployed quite easily, but when you start to require triggers, variables, etc, it can be a little daunting.

    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.

    GTM does not provide support. This is one of GTM's biggest issues but it's due to the level of customization for each website. If your team thinks they would heavily rely on the need for a support staff it is probably better to invest in a paid service with a team that can support your needs.

    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.

    I thought there was a little bit too much emphasis on AdWords stuff, not enough on the generic application of GTM.

    Planning and communication will help greatly with an in-house implementation. If there are large teams, try to limit the number of people involved to 1-2 developers (back-end dev may be necessary depending on your platform), one analytics marketer and one project manager.

    We moved to GTM from a standard Google Analytics implementation. GTM is much more flexible and easier to make changes, especially as the changes relate to multiple sites and environments. While there is a learning curve when figuring out how to use GTM, I believe the change has been worth it because it helps us understand at a more fundamental level how our tracking works and gives us a lot more control over what we track and how.

    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.

    Return on Investment

    • GTM is very useful to determine if a particular element on the site is useful (i.e. is it being watched, is it being clicked, does it help customers navigate through more pages). As an SEO person, I can use this information to decide what to optimize for but also to track progress and see improvements in engagement.
    • With the use of Google Tag Manager, I was able to easily inject an A/B testing tool which lead to several improvements in lead generation.

    • 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.
