Google updated snippet documentation with a new section about "read more" deep links and how to boost your odds of getting them to show up in Search results for your content. Here it is:

> To increase the likelihood that "read more" deep links appear for your site in Google Search, follow these best practices:

> • Make sure content is immediately visible on the page to a human (and not hidden behind an expandable section or tabbed interface, for example).

> • Avoid using JavaScript to control the user's scroll position on page load (for example, don't force the user's scroll position to the top of the page).

> • If you make history API calls or window.location.hash modifications on page load, make sure you don't remove the hash fragment from the URL, as this breaks deep linking behavior.
