All SEO Factors Affecting Page Ranking in Search Results (part 3)

3. Meta tags

3.1

Value types can be as follows:

1. None : Never sends referral data:

2. None When Downgrade : Transfers referral data to sites on HTTPS, while data is not transferred to sites on HTTP.

3. Origin Only : Transmits data about hosts and subdomains. In this case, the URL, as a rule, has the following form: https://moz.com/example.html would simply send https://moz.com (example).

4. Origin When Cross-Origin : Transmits complete URL information in cases where configuration is done according to Scheme 3, regardless of which protocol uses an HTTP or HTTPS site.

5. Unsafe UR L: Always transmits the full URL of the referrer. It is important to understand that this setting is the least secure. A portion of unencrypted data can be transmitted. By default, URL fragments, usernames and passwords are automatically excluded from the URL.
