So - for my blog pages - I have a sidebar CTA that is the same on all blog pages - and it links to another page on my site. I want to take the URL of the blog page that someone is on when they click the link to add that pages URL slug as a UTM on the click.
So - they land on www.mysite.com/blog-page-1
then they click my CTA - and they go to www.mysite.com/registrationpage
but I want them to go to www/mysite.com/registrationpage?utm_source=blog-page-1
Here is my site Read-Only: LINK
