Ad Reporting & Analytics
Comparison of Ad Reporting & Analytics features of Product A and Product B
I use Google Tag Manager (GTM) daily and create tags/triggers for all of our client's websites. It is easy to set up but for some of my tasks, the process does get repetitive so it'd be nice to have a default setting I can use when I have to create accounts, and then tweak/add things to them as needed. It is a great way to collect data and have code on the site without having to log into the site builder all the time. It makes it convenient to make edits or add code after our client's sites go live with us.
I've use Sizmek as media analytics and reporting tool. Unless a site doesn't work properly with Google DoubleClick, I rarely recommend Sizmek over DoubleClick. It can do everything DoubleClick does, but with almost twice the hassle. One Area that makes it easier to track is that ads are given individual tracking ID's that creative can look up and search by when indexing and testing to make sure all ads are working and input.
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.
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.
Google Tag Manager makes tracking traffic to our websites effortless, which enables our developers to focus on other tasks. Setting up a new instance takes only minutes and additional scripts can be added/modified without touching the source code of a site in production. This enables our marketing directors to coordinate tests and experiments with minimal effort.
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.
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.
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.
For me the main point here is the support, all the adservers offer more or less the same functionality and capabilities. The real advantage you will gain using Sizmek will be their customer support team and their open approach with other vendors.
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.
