How to pass the Robot Meta Tag test?
This document details how the page- and text-level settings can be used to adjust how Google presents your content in search results. You can specify page-level settings by including a meta tag on HTML pages or in an HTTP header. You can specify text-level settings with the data-nosnippet attribute on HTML elements within a page. Keep in mind that these settings can be read and followed only if crawlers are allowed to access the pages that include these settings.
