Add cookie for maintaining UTM parameters after navigating from landing page
Open issue originally logged here: https://github.com/sourcegraph/sourcegraph/issues/10639 Background We can't report the effectiveness of digital campaigns unless UTM parameters are maintained once the browser navigates from a landing page. Results right now are showing close to 0 MQLs for all marketing campaigns through the utm_source parameter, which I don't think is true.

This is automatically set by HubSpot for each contact." I attached a spreadsheet of all MQLs from 2020 having the 'First page seen' that contains 'utm_source'. I highlighted the MQLs that originated from google ads. It shows 2 additional google MQLs contact records:
@aileenrose FYI I haven't looked at your comment in detail yet but there was PII in your comment that I removed (this repo is public)
@ebrodymoore you can delete comment history as well. Otherwise this is visible to everyone.

In the future if you ever see this feel free to tag a GitHub admin to do so!
And @aileenrose the xls you uploaded contains a LOT of private data. I've deleted the link and the comment history, and reached out to GitHub to delete the file from their cloud.
