During reading a SEO blog, I found a term “Meta Referrer” Can anybody explain what the mean of it? When should we use this tag? After a deep study I get an answer that – the process of referrer data stop when we shift server from http:// to https:// to identify referrer URLs after shift in Https we use Meta Referrer. But I need a detail explanation? Can anybody help me to find the solution?

Referrer tag tells the search engine and affiliate marketing programs from where the traffic is coming. Refer tag is very useful for affiliate marketers.
