Contentful vs Google Tag Manager

• Contentful provides organized, flexible data models with support for a variety of data types and content editors (e.g. WYSIWYGs, form fields, raw text areas).
• Contentful has great built-in versioning features with history and draft states so it's easy to make updates and revert when needed.
• Contentful has an intuitive user interface and good support for multiple spaces (which can be helpful for companies that need separate projects for dev/staging/production).

• Code injection is simplified with Tag Manager. Facebook Pixel, Google Analytics, Marketo Munchkin, HubSpot tracking, Hotjar, CallRail, the list goes on. One stop, no constantly bugging the devs to install new code.
• Need to track onsite events? Build a single listener or trigger, and apply that trigger to countless different applications. A user form fill can trigger an AdWords and Facebook conversion, tag a Hotjar recording, signal deployment of a pop-up or just about anything else javascript-driven.
• GTM is basically coding light. For non-developers who might be terrified of GitHub, it makes features like version control, forking/branches and draft / deploy mode approachable.

• There is no real tutorial for GTM, and the one that exists in google analytics academy is very basic. Google should create a library or a document that specifies how to use each of the elements available in GTM. Earlier today I was trying to use a feature for a GA tag that I've never used before, but couldn't find any information about it.
• They are not great at integrating with Facebook. FB is one of the most popular platforms for advertising, they should have created a specific Facebook tag by now to help marketer with their tracking.
• It's hard to connect several actions taken by the same person in 1 tag. For example, there is no easy way of tagging a multiple step action. Each tag will fire individually on each action instead of firing on conditions.

• The google tag manager certainly generated an increase in the ROI of our clients, because, with the agility in the management of tags, it was possible to reduce the IT queue, and now the management of the tags happens to be done by the Marketing and media area itself.
• Reduction of an IT staff
• Saving time in organizing hundreds of tags in the backend and starting to use the GTM, everything was centralized in one place
