Google is rolling out a new robots tag that gives sites more control over content that gets indexed in search results.
A new robots tag, called indexifembedded, lets websites give Google more direction over which content to index in search results.
With this tag you can tell Google to only index content on a page if it’s embedded through iframes and similar HTML tags.
The indexifembedded tag overrides the noindex tag.
That means you can use noindex to keep a whole URL out of search results, and apply the indexifembedded tag to make a specific piece of content indexable when it’s embedded on another webpage.
