The referral source condition will not work when referring from Https protocol to Http protocol. If your website is on Http protocol, and the referrer is an Https website you can use the dynamic link condition instead.

The following table presents operators and actual referrals. It illustrates whether dynamic content will be displayed or not displayed if your website is on Http protocol

Operator	Domain/ URL/ Term set by the admin	Visitor’s actual Referrer	Result (Will dynamic content be displayed?)
URL is	shoes.com	http://shoes.com	Yes
		http://www.shoes.com	Yes – The condition is met whether you write www or not
		https://www.shoes.com	Yes – If your site uses an HTTPS protocol No – If your site uses an HTTP protocol
		https://shoes.com	Yes – If your site uses an HTTPS protocol No – If your site uses an HTTP protocol
URL contains	shoes	http://shoes.com	Yes
	sh	http://shoes.com	Yes – It doesn’t matter where in the URL your letters appear
	red	http://shoes.com/red	Yes – It doesn’t matter where in the URL your term appears
