How Can I Get The Correct Referer Via Javascript If The Referrer Uses Https?

I use document.referrer to read the referrer url via JavaScript e.g. if a user clicked a google search result link and lands on my website: http://www.google.com -> Click on sea

Solution 1:

When you search from https://www.google.com, websites you visit from our organic search listings will still know that you came from Google, but won't receive information about each individual query.
