    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.

    I think One Signal is very well suited for mobile app owners who want to be in touch with their user base more easily by sending push notifications and in-app messages. I'm not sure how well that works for SMS messaging as I haven't yet tried it. I wouldn't necessarily recommend it if your in-apps are very rare.

    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.

    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.

    • Is still in development: we know OneSignal is still in development and sometimes it takes longer to create or fulfill certain features.
    • Payment: payment menu is not at the glance, [and] is just difficult sometimes to find -it is a minor issue.
    • Send to certain custom segments through specific OneSignal IDs; you can do it though API doing a GET call with tools like Postman. If this can be done from OneSignal it 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.

    Usability
    Google
    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 give an 8 in this question mainly for 2 reasons: the products even if they look like complete and are highly customizable and usable, they are still missing some logical features. For example, send messages to a list of users - now days you can do it with postman and get calls. A second example is App messaging that is still in development and has many opportunities.

    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.

    Their customer support has been top-notch. They are able to assist you in getting through any problems that you may have and respond in a very timely manner. I've dealt with them on 4-5 instances over the years and my issues were always resolved within a matter of a few business days.

    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.

    In my opinion, OneSignal documentation / API is more friendly [than] Firebase. Maybe because Firebase is already "too big," but OneSignal is focused on one solution that giving our notification through to our customer. In that case, OneSignal is chosen by our company. Several years after that, Firebase announced it supported [the] iOs platform too but our company already using OneSignal to our notification provider.

    Return on Investment
    Google
    • 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.
