Google Tag Manager vs. Hotjar

Google Tag Manager is well suited when the marketer or marketing team does not work closely with the developers. In this scenario, it means that the marketer can deploy 3rd party tools such as live chat widgets, advertising pixels, and much more themselves in a timely manner. Google Tag Manager may be less relevant in an organization where the marketer is also the developer or has a strong development background, where they can implement the 3rd party tags directly on the site when they need. But even in this instance, there's still great benefit in using Google Tag Manager.

Hotjar is well suite for organizations that want to get a good glimpse into user behavior on their websites. The tool is easily installed through Google Tag Manager, and then users simply select which pages or paths they want the tool to analyze. After a few days, users can start seeing patterns develop, helping them understand what areas of the user journey flow they need to test out and improve. Hotjar is primarily for web-based experiences, not for mobile applications and other non-web digital applications.

• 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.

• Heat mapping is great on Hotjar. It is a good place to start when you are looking at the UX & CRO on your website. You can see the % of people clicking on elements on a page, how far they scroll, and mouse movements.
• Hotjar is great for session recordings. These record the mouse movements, clicks, pages and scrolls of a user in video format. You can watch these to investigate what works well on a site and identify potential roadblocks and bugs.
• Hotjar is great as it ensures that users details are anonymous; for instance, if you are watching a session recording, you cannot see what a user types in a form field, as Hotjar blanks this out.
• Hotjar has a poll function, so you can have polls on your website.

• 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.

• The video recording feature is very slow to use. I know there is a very powerful process going on (saving your CSS and the DOM movements you make) but anyway it's slow to use.
• Hotjar itself is heavy and has effects on your load times. This is a very important issue and I hope they're working on that.
• Adding more segmentation would be nice. For example, being able to connect your API or more information to show relevant polls or feedback buttons to certain users. Aggregated info is hard to process.

Until a strong case or need arises for enterprise tag management, I cannot see any reason why we would discontinue using Google Tag Manager. Even if we were to switch to a different vendor, we would still likely use Google Tag Manager to manage Google Analytics code and Google AdWords conversion and remarketing pixels

Even though the heat maps and user recordings were useful, our website was significantly slowed down after we installed Hotjar, so much so, that it took over a minute for our blog to load. The data that we gathered was not worth the length that it took our website to load.

Google Tag Manager is the best tool to centralize everything in one place including marketing, analytics, integration with third party tools for AB testing, cookie management, etc. it includes user's management, debugging features, tag approval process, etc. it also saves time and resources by not relying on developers.

So easy and simple to use! Straightforward anyone in the team is able to easily go in and set up anything in Hotjar. The UI is really simple. Whenever you give feedback to Hotjar they continously take on board the feedback and improve the tool.

It depends wether you are seeking official support from Google itself, in which case it would be rated very low because it's not their business model, they would rather have you work with one of their Google Analytics Certified Partner (GACP). In terms of self-served support, Google offer extensive documentation at https://developers.google.com/tag-manager/, recently revamped training (https://analyticsacademy.withgoogle.com/course05/preview), has active forums and user community (https://plus.google.com/u/0/communities/104865292981489764063) which can typically answer even the most advanced questions.

Hotjar is a SaaS-based company, and as such has a good support service. Users can quickly submit support tickets through Hotjar's online portal. Enterprise customers get access to additional support members and have SLAs to support their larger, more complex needs. Overall, Hotjar is extremely reliable and I've never had to reach out to customer support.

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.

With GTM we are able to integrate GA4 with other platforms we use. We can then send data to GA4 and AdWords and relay that info to our customers. They all work well together and give us a good opportunity to report back to our clients. We haven't used a ton of other products that do what GTM does, so I guess it has a leg up there

Compared to Sprig and Usabilla, Hotjar has robust functionality. Again, as stated earlier, the ability to summarize rage clicks, trigger recordings for a/b experiments, and run intercept surveys on mobile is very useful. Hotjar is also noticeably more intuitive to use than Usabilla, with a cleaner interface and navigation.

• GTM has allowed us to show positive ROI for multiple clients via connecting their two websites so that they could see the amount of money advertising generates.
• GTM has also shown a positive ROI from an internal perspective as we can use templates to immediately upload our standard, customized event tracking which saves hours of testing and configuration.
• GTM's lack of error catching features has caused more time and individual testing but the improved preview feature has helped save time.

• Our UX team can now use hard data to back up and validate design decisions that we make. Our role as usability experts is becoming more respected and integral to business objectives because we now have data that can back up our field of study and prove that our roles are demonstrably useful and necessary.
• HotJar allows our small team of 3 UX designers to get research data as if we were a much larger team. Instead of painstakingly using our time to do guerrilla research, endless user observations, and other types of manual testing, we can now get a significant portion of our data from HotJar.
• Using HotJar is actually giving our team a sense of excitement and enjoyment in our day-to-day usability work. Instead of seeing UX as a chore, HotJar is making data gathering and analyzing more fun, because we can see tangible results from a much larger pool of user/user-data than we could in the past.
