Do I need Google Tag Manager?
Deciding if you need Google Tag Manager depends on your business and your goals. It would be best to discuss your needs with an expert before making a decision. Be aware that GTM can be difficult to set up if you don’t have adequate technical knowledge.
What are the advantages of using Google Tag Manager?
Google Tag Manager allows you to customise the data that is sent to Google Analytics. Multiple users can be given access to the account (with user-specific permissions) allowing you and your team to collaborate easily.
GTM allows you to update your tag across your site quickly and easily. Managing your tags in one place makes it easier to keep track of the code on your site and makes it less likely that you will have old forgotten (possibly broken) code buried in your website.
If GTM is set up correctly it feeds into your Google Analytics account, giving you access to more specific data on your website visitors.
What are the disadvantages of using Google Tag Manager?
Google Tag Manager is not easy to set up or use if you don’t have adequate technical skills. To get the most out of it, it should be set up by someone with developer knowledge. If GTM is set up incorrectly it can affect your website page structure and your page load performance. There are no reports or analysis tools in GTM, it compliments Google Analytics but is not a standalone tool.
