Google search starts highlighting results directly on webpages

This worried me at first. Either Google has found a way to inject their content on to pages you visit via search results OR they're taking their position as your analytics or ad tool and repurposing it to deliver functionality you haven't opted in to... but looks like this is a feature in Chrome, so it's not so bad.

These kinds of features are really useful for users and if it's a part of the Chrome product, great.

If you see this working in Safari or other browsers, then it's most likely an AMP page that someone has asked Google to deliver on their behalf.
