Hey Roman! I simply read the article. I got two questions if you allow me:

1 - In what situations this will occur or is prone to occur?

2 - Do you know if, after a login on a website from a user who landed on a page via a ppc campaign, the GCLID/UTM parameters get lost? Thanks

Hi, it happens because passing the GCLID parameter through URLs is disabled e.g. in conversion linker in GTM / SGTM. Sometimes this option in conversion linker is causing problems for the websites functionality and it needs to be disabled.

Yes, if the GCLID parameter, or any other parameter in the URL (utm) is available only on the landing page and then after clicking on another page, this parameter is lost.

However, this behavior may vary from site to site.

Situation can be solved either by what I write in the article. Or in BigQuery retrospectively, but I have no experience with that.

Hi Roman! But isn’t suppose the use of conversion linker to track conversions in GAds, be more precise instead of importing them from GA4? Which leads to another question, so importing events from GA4 to GAds doesn’t cause that “issue”? Thank you
