Appending UTMs to the buttons using class name attributes
<a href="https://www.someoutgoinglink.com/" class="utm-out">
HandL UTM Grabber automatically scan all the links and buttons having utm-out
class and append all the UTMs automatically so your final URL will be like this.
<a href="https://www.someoutgoinglink.com/?utm_source=google&utm_medium=cpc&utm_campaign=spring_sale&utm_term=term&utm_content=content" class="utm-out">
utm-out
also works if it is at the parent level. For example
<div class="parent-div utm-out">
<a href="https://www.someoutgoinglink.com/">
</div>
This will also populate all the UTMs like this
<div class="parent-div utm-out">
<a href="https://www.someoutgoinglink.com/?utm_source=google&utm_medium=cpc&utm_campaign=spring_sale&utm_term=term&utm_content=content">
</div>
