Fire GTM tag only if on homepage of the site

Question

The homepage can also have extra GET params (e.g. utm tags and similar marketing variables). How can I make it work? Simple "end with http://example.com or http://example.com/" doesn't work cause the url might be http://example.com/?utm_campaign=text&...

Thanks!

Answer 1

The best practice is always install the GTM along you domain and execute it whenever you need. To launch a tag only in the home you need to use the following trigger. Add this on you custom HTML tag, take care of the equals.

Answer 2

I know this is an old thread; but I found it after I solved this myself. I created a trigger for Page Path matches RegEx and used:

^\/(\?(.*))?$

What that does is matches for ONLY the hostname with no path (www.domain.com/) OR matches if a ? follows the /.

Might be another way to do this. Completed trigger:

Answer 3

I've achieved the same using Page Path matches RegEx

^\/$|^\/\?

This means: match a string that begins (^) and ends ($) with / OR (|) that begins with /?

\ precedes special characters to denote that they should be treated as text and are not part of the expression.
