If you have a marketing department that wants to be agile and measure valuable goals for your company, then GTM is the way to go.
You will be able to track almost any event of value that you want on the site (without adding any extra code, thanks to auto-event listener), add new marketing tools if needed in minutes and send events to multiple platforms.
This has huge value for your company if you think about it: measuring your efforts quickly and changing course if it is not working can save tons of money. I believe almost anyone who has a site on the internet can benefit from it because of how much time it saves (considering it's even free!).

Just beware: GTM opens the door so you can add any piece of code you want. Someone without much experience can overload the site or affect site speed.

Tag Manager is great for any website, especially if you are integrating a variety of different services into your website. When using tag Manager you don't have to dig through code to figure out where a snippet of code is hiding. It is all organized and labeled.

Google Tag Manager is well suited for service and e-commerce businesses scenarios like tracking specific data especially for specific products tracking click-through rates as well as sales. I will say is less appropriate if you don't have a large number of things to track or a much smaller business is starting off you might want to try and outside tracking system because it is extremely complicated.

Google Tag Manager removes the need for deprecated documentation or anything complicated that your company would lose track of. It replaces a lot of unnecessary back-and-forth between different teams within a business. It lets marketing work more independently of the rest of the company and allows for quick iterations and quick fixes. It also is really helpful if you have clients that use it because permission sharing is great.

GTM is an easy solution for tracking users and measuring digital advertising.

I would really recommend GTM. It's an easy-to-learn tool that can achieve great things.
I think every marketer should know how to use GTM, at least the basic concept of creating tags and triggers. There are many non-Google online tutorials and scripts that other people have already written, which makes it even easier to achieve your goal.

Google Tag Manager is an excellent tool for adding third-party scripts. When something goes wrong with them or when they need a quick change - you don't need to wait for your next release date. Just get the fix done, check that it's working correctly with the preview mode, and publish.

Any scenario in which you want to do any level of analytics on web traffic is very well suited for GTM. It can trigger third-party pixel events with custom HTML tags as well as any of the native tags that are built into the system, so it can help the less technically savvy marketer implement the solutions they historically would have to ask a webmaster or developer for help with.

In general Google Tag Manager is well suited to help marketing professionals manager their tracking pixels for Adwords, Analytics, Remarketing, and other tracking pixels, easily and in one place. It lets you get the tags/pixels created and deployed live onto the websites without having a lot of time taken up by any coding or development professionals.

Google Tag Manager is an ideal solution for teams who would like to get new javascript tags loaded on to their website, or edit existing tags without having to wait for a dev cycle. In some dev sprints, it could take weeks just to make a small change to a tag. Google Tag Manager would probably not be needed for a small personal website or blog in which it was managed by one person.

For our social media data tracking, it's perfect when clients have website business objectives other than those that can easily be tracked by Facebook's pixel. Facebook is ideal for simpler cases of tracking (ex: page loads) but GTM is better suited when there are other actions on site that are helpful to track (video views, clicks on buttons, email sign ups, facility finder submissions, etc.)

I think GTM is particularly well-suited for organizations that run multiple sites and have an interest in managing to track across and between those properties. It makes tracking across domains much simpler than the standard Google Analytics setup. It might not be worthwhile to switch to GTM if you run a single site or don't have plans to implement detailed user engagement that requires a lot of custom code.

Google Tag Manager is great for increasing agility in publishing, changing, and managing marketing tags and other tools. For an online business, that makes all the difference. It is free and has a friendly interface, and we can say that it does not take a programmer to start using it.

Google Tag Manager is perfect for organizing tracking scripts for your sites. If you have multiple tracking scripts that you implement on your site(s), then Google Tag Manager is a great tool that'll make your life easier when managing your scripts. If you have many rules or want different tracking scripts to fire on certain pages or certain events, GTM is a big help that can manage this for you.

For most websites that desire tracking, Google Tag Manager is the way to go. Apparently, there is even GTM for mobile application, although I haven't looked at this part of it. The only time I would consider not looking into GTM is for websites that need to be overly quick in loading, and cannot afford to have the little bit of overhead that GTM adds to a page load.

Google Tag Manager is best suited for managing several tracking scripts in one place. You can give each tracking pixel a unique name and add it to any site you manage. Google has made adding/removing and testing tracking pixels simple and require configuration. .

Google Tag Manager is great if you have limited IT help, or don't want to bother your IT manager, and need a relatively easy way to tag and track your website users' actions. I don't think it is suited for websites that lack content, or that don't have a significant amount of lead generation integrations. For example, an information-based website with a blog theme would not need Google Tag Manager.

GTM is really good for monitoring usage of the entire website to see what parts perhaps need testing or to understand visitor behaviours.

Great first tag management solution, also great for smaller organizations and those with limited budget.

GTM is useful when you are planning to install multiple types of tracking, such as Google Analytics and Facebook Pixel to your website.

You should use Google tag manager if you have someone on your staff who has analytics and development chops, and you are interested in measuring interactions that go beyond simply what page was viewed or what button was clicked. If you need to handle retargeting ads specific to a particular interaction, or you want to measure interactions in a particular sequence over the course of a session, google tag manager is great.

If your organization lacks someone with these skills, look into a solution like Heap if you are small enough.

- Deploying simple tags which don't need additional data from the webmasters is very easy (e.g. live chat, Hotjar, Google Analytics Pageview, basic Adwords remarketing)
- Deploying complex tracking like Enhanced Ecommerce or Dynamic Remarketing is best done with a well planned and deployed Data Layer

GTM is really good at making the basic tags easy, if you're going to use Google Analytics, Google Adwords or DoubleClick. You don´t need to look for another tool. If you have some stuff like Criteo or Crazy Egg this is your tool. But if you have to get some interactions without help of IT it is difficult sometimes to get the data.

I would recommend it, as the insights are extremely valuable when connected with Google Analytics. If you want to know the age, gender, nationality of your users this is the tool for you. If you want to know what users click on, what pages they land/exit on, or see their journey through your website, then this is the tool for you. However, it is quite technical and can be hard to use unless you have a step-by-step guide. This tool does not show you videos of your users on your website, or heatmaps, or provide reasons behind their behaviour. Nor have I found a way to get notifications.
