What is the standard for processing the ‘click_id’ portion of a page url?
I see in on the canonical events page that the click_id is tracked as ‘mkt_clickid’ - does this extend to all kinds of click_id values?
I am sure Google is there, but are click_ids from, say, Facebook and Marketo covered as well? And if so, is there a conditional ‘source’-type column available, so I can see something like the source for each clickid? (These would be in cases where a utm_source parameter may not be included in the URL, so I’m wondering if the click_id source could at least be inferred.)
In my situation I am extracting this information (for testing) from referring links, so I’ve been writing my own SQL for it, but I wanted to make sure I am matching what is done to define the mkt_* columns.
